Summary

Vattenfall is planning to build a new nuclear power plant on the Värö peninsula in

the Varberg local authority area. The nature of the planned operations is such

that, under the Espoo Convention, they require consultation with the neighbouring

countries concerned. This report provides Vattenfall with a basis for assessing

which countries could be affected and should therefore be notified. Vattenfall

takes the view that only a hypothetical accident involving a core meltdown could

give rise to consequences outside Sweden’s borders. The report is therefore

based on such a hypothetical accident, allowing an assessment of the

consultation group to be made on the basis of a hypothetical worst-case scenario.

The results of the calculations show that radiation doses are high in the

immediate area but decrease rapidly with increasing distance. The lifetime dose

for a one-year-old child and adult on Läsö, which is the nearest foreign landmass

located some 50 km west of the Värö Peninsula, is below 10 mSv. At distances

greater than 250 km from the Värö Peninsula, no lifetime doses in any age group

will exceed 1 mSv. By comparison, natural background radiation, according to the

Swedish Radiation Safety Authority, gives residents in Sweden a dose of 1–2

mSv annually.

In neighbouring countries, only people living in Denmark and the coastal areas of

southern Norway receive lifetime doses above the natural annual background

radiation as a result of the radiological accident.

1. Introduction

Vattenfall is planning to build a new nuclear power plant on the Värö peninsula in

the Varberg local authority area. The nature of the planned operations is such

that, under the Convention on Environmental Impact Assessment in a

Transboundary Context (Espoo Convention), they require consultation with the

neighbouring countries concerned. The Swedish Environmental Protection

Agency is coordinating the Espoo consultation and, with this report, Vattenfall has

provided a basis to enable an assessment of which countries could be affected

and should therefore be notified. Vattenfall takes the view that only a hypothetical

accident involving a core meltdown could give rise to consequences outside

Sweden’s borders. The report is therefore based on such a hypothetical accident,

allowing an assessment of the consultation group to be made on the basis of a

hypothetical worst-case scenario.

The land area considered is within a radius of up to 800 km from the site in

question on the Värö Peninsula, please see Figure 1.

Figure 1. The land area around the site in question on the Värö Peninsula out to a radius of 800 km.

The nearest foreign land area is the Danish island of Läsö, located about 50 km

west of the Värö Peninsula, please see Figure 2. Since the concentration of

airborne and ground-based activities will be lower further away from the release

point of a nuclear accident, other parts of Denmark and other neighbouring

countries will be less affected than Läsö.

Figure 2. The map shows the distance, as the crow flies, between the Värö Peninsula and the Danish island of Läsö,

taken from Google Maps. The distance between Värö Peninsula and Läsö is approximately 50 km.

The design of the proposed nuclear power plant has not been fully defined, so the

calculations in this report are based on a conservative, generic source term1.

Dispersion conditions and exposure data have been selected as far as possible in

relation to the Nordic circumstances. The radiation dose caused by a radioactive

release is different for children and adults because the exposure pathways are

different for different age categories. For example, food intake differs between

these groups. To cover the variations, this report presents results for one-year-old

children and adults.

2. Evaluation criteria

Transboundary consequences of a radiological accident have not been assessed

against any dose constraints or dose limits. Instead, this report makes a

comparison with natural background radiation which, according to the Swedish

Radiation Safety Authority, gives residents in Sweden an annual dose of 1–2

mSv. The Danish Health Authority and the Norwegian Directorate For Radiation

Protection and Nuclear Safety set values for natural background radiation at the

same level as the Swedish Radiation Safety Authority.

3. Method

The source term assumed to be dispersed in the surroundings as a result of the

accident is presented in Table 1. It has been selected to cover emissions from a

hypothetical accident involving a core meltdown in a light-water nuclear reactor. In

practice, such a release means that the reactor cooling system is not working and

all the cooling water has boiled away, causing the core to be exposed and melt.

The source term is based on a release of 100 TBq Cs-137, which currently

applies as a release requirement for existing nuclear power in Sweden in the

event of highly unlikely events and situations. Emission requirements for new

nuclear reactors are likely to be more stringent than this, so this should be

regarded as a conservative source term covering both large and small new

reactors. Other nuclides in the source term are related to the release of caesium.

1 Source term is an accepted concept in the nuclear industry and refers to the size and composition of the release in

a nuclear accident.

6 (9)

The release time is 24 hours and the release height is 20 metres. The analysis

assumes that the release can occur on any day of the year, taking into account

the weather situation on that day, i.e. 365 different weather situations are

considered.

Radiation doses have been calculated for people at a distance of 1–800 km from

the point of release.

core meltdown in a nuclear power reactor on the Värö Peninsula.

The dose calculations have been carried out using the JRODOS tool, developed

by the Karlsruhe Institute of Technology. In the dispersion calculation, the

radioactive substances are assumed to be released as sequential puffs and, for

each time step, the transport, diffusion and deposition of radionuclides on the

ground has been modelled taking into account local meteorological and

topographical data.

The following exposure routes have been included:

- The short-term perspective

o External dose when the radioactive plume passes (cloud dose)

o External dose from radioactive substances deposited on the

ground (ground dose)

o Internal dose from inhalation of radioactive substances in the

plume (inhalation dose)

o External dose due to skin contamination

7 (9)

- The long-term perspective

o External dose from radioactive substances deposited on the

ground (ground dose)

o Internal dose from inhalation of radioactive material swirled up

from the ground (inhalation dose)

o Internal dose from consumption of contaminated food

JRODOS can define how much the population in different geographical areas

consumes different foods. As assumptions on land use and intake affect

calculation results, the modelled area has been divided into different areas with

varying food intake based on what is grown and what is statistically consumed in

these areas. Depending on the area over which the radioactive plume travels,

there will be different consequences via the exposure route of food intake, even if

these areas are the same distance from the release point and the weather

conditions in the areas would be similar. The results presented in Chapter 4 are

based on the maximum dose at each distance for each of the 365 weather

situations.

4. The results

The impact of the radiological release in neighbouring countries has been

described in terms of effective dose to an individual. The effective dose for one-

year-old children and adults is presented in Figure 3 and Figure 4. The doses are

high in the immediate area but decrease rapidly with increasing distance. At Läsö,

about 50 km west of the Värö Peninsula, the lifetime dose2 for a one-year-old

child and adult is less than 10 mSv. The dose after seven days’ exposure is less

than 1 mSv for an adult and less than 3 mSv for a one-year-old child at Läsö.

At distances further than 250 km from the Värö Peninsula, lifetime doses will be

less than 1 mSv, i.e. less than the approximate level of annual dose from natural

background radiation. As can be seen from the distances shown in Figure 1, only

residents of Denmark and the outer part of the south-east coast of Norway may

receive lifetime doses above the annual natural background radiation following

the hypothetical meltdown accident described in this report.

2 The lifetime dose describes the radiological impact on an individual from the time of the accident and for the rest of

their life. For a one-year-old child, this period is 70 years after the accident and for an adult, it is 50 years after the

accident.

5. Discussion

The results presented in this report show that after a hypothetical nuclear

accident with a core meltdown on the Värö Peninsula, the doses to people in

neighbouring countries are relatively low. Compared to the dose from natural

background radiation of 1–2 mSv that a person living in Sweden receives each

year, the impact of the radiological accident is small. The calculations have

consistently been made using conservative approaches, and it is reasonable to

believe that the impacts in reality would be even lower. Some of the assumptions

that drive the results in a conservative direction are presented below:

• For each distance evaluated, the geographical point giving the highest

dose has always been selected. This means that, although this point is in

the centre of the North Sea, it has been included in the evaluation.

• No crediting of protective measures3 has been done, meaning that people

evaluated have been assumed to be outdoors every second for a whole

year. The considerations of sheltering for parts of the day and restrictions

on food intake would further reduce the consequences.

• It has been assumed that all food eaten comes from the place where the

evaluated people live. Importing food from non-contaminated sites would

further reduce the impact.

6. Conclusion

The radiological impact on residents in neighbouring countries in the event of a

release from a hypothetical accident involving a core meltdown at a proposed

nuclear power plant on the Värö Peninsula has been evaluated. Radiation doses

to a one-year-old and an adult have been calculated for distances out to 800 km

from the release point. Calculated lifetime doses at 50 km, a distance

corresponding to the nearest inhabited foreign landmass (Danish Läsö), are less

than 10 mSv for both a one-year-old and an adult. At distances greater than 250

km from the release point, lifetime doses are less than 1 mSv, which is

approximately equivalent to the normal annual background dose to the general

public in Sweden.

3 Protective measures include sheltering, taking iodine tablets, food restrictions, etc.

1. Introduction

1.1. Background

Sweden has set itself the target of achieving zero net greenhouse gas emissions

by 2045. Sweden imports 130 TWh of fossil fuels annually, with oil accounting for

more than 100 TWh. Oil is supplemented by coal, coke and natural gas.1

Sweden needs to achieve our climate targets while strengthening our

competitiveness through extensive electrification of industry and the transport

sector. In addition, the Swedish Parliament has adopted a target that electricity

production in Sweden should be completely fossil-free by 2040.2 To meet the

increased demand for electricity, Vattenfall believes that all available sources of

fossil-free power need to be expanded. Nuclear power can produce large

amounts of electricity using minimal amounts of fuel over a minimal surface area

and will constitute an important part of the fossil-free electricity system in meeting

Sweden’s increasing electricity needs.

1.2. Purpose of operation

The purpose of the planned operations is to produce fossil-free and plannable

electricity using a new source of nuclear power on the Värö Peninsula in the

Varberg Local Authority Area. Production should be in place by the mid-2030s.

Predictable production will help stabilise the electricity grid, and for the electricity

system to function, there must be balance. This means that the generation of

electricity at any given time needs to be equal to its consumption.

There are two types of electricity generation: plannable and non-plannable.

Nuclear power and hydropower are both plannable forms of energy, in the sense

that electricity generation is predictable and can be planned in advance, which

helps to strengthen the power system’s security of supply. Wind power and solar

power are weather-dependent and therefore non-plannable forms of power, as

generation depends on the weather and cannot be planned in advance.

The site on the Värö Peninsula, see Figure 1, has been designated as being of

national interest for thermal power-based energy generation and is adjacent to

the existing Ringhals Nuclear Power Plant. It is strategically located on Sweden’s

west coast, between the metropolitan regions of Gothenburg and Malmö, whose

demand for electricity is not only high, but is expected to increase because of

planned industrial investments linked to the green transition. As a result of the

existing operations at the Ringhals Nuclear Power Plant, there is already

infrastructure at the site that can be jointly utilised for new nuclear power

operations.

Vattenfall also believes that the closure of Ringhals 1 and 2 has made it possible

to connect new power generation without major investments in the national grid.

Moreover, Vattenfall has had and maintains a successful collaboration with

Varberg Local Authority. Indeed, the region has developed expertise among

subcontractors and authorities regarding nuclear power operations. This makes

the Värö Peninsula a suitable choice for the first site in Sweden to establish new

nuclear power to meet the country’s demand described above.

1.3. Purpose of document

The planned operations are subject to a permit under Chapters 9 and 11 of the

Environmental Code (1998:808) and are assumed to have a significant

environmental impact under Article 6 of the Environmental Assessment

Regulations (2017:966). For operations that can be assumed to have significant

environmental impact, no investigation consultation is required, and no such

consultation has been carried out for the planned operation.This document

provides the basis for the scoping consultation to be carried out pursuant to

Chapter 6 of the Environmental Code.

The main purpose of the consultation is to exchange information with and provide

local residents, the public, authorities, organisations and other stakeholders with

the opportunity to submit comments on the content of the upcoming application

for permit, the environmental impact assessment and related documentation, as

well as to consult on the location, scope and design of the operations and the

environmental effects it is likely to have.

A preliminary assessment shows that the planned operations are covered by the

Act (1999:381) on Measures to be Taken to Prevent and Limit the Consequences

of Major Chemical Accidents (Seveso Act). This means that the consultation

must, in accordance with Chapter 6, Article 29 of the Environmental Code, also

cover the prevention and containment of major chemical accidents resulting from

the operations. The consultation also concerns factors in the environment that

may affect the safety of the operations, in accordance with Article 13 of the

7 (62)

Seveso Act, with particular focus on the distances to other operations covered by

the Seveso legislation.

As the operations may have a significant impact on a nearby Natura 2000 site,

the consultation also includes examining the possible need for a so-called Natura

2000 permit (Chapter 7, Article 28 a of the Environmental Code) The forthcoming

environmental impact assessment will provide the basis for assessing the need

for and, where applicable, the granting of such a permit.

The planned operations are of such a nature that, under the Espoo Convention

(Convention on Environmental Impact Assessment in a Transboundary Context),

they entail an obligation to also consult with the neighbouring countries

concerned. Consultations under the Espoo Convention are planned to take place

both on the planned applications for permit for the development and operation of

the nuclear power plant and on the planning procedure under the Planning and

Building Act (2010:900). The Swedish Environmental Protection Agency (EPA) is

coordinating the Espoo Consultation, and Vattenfall will have an ongoing dialogue

with the Swedish EPA regarding the design and implementation of the Espoo

Consultation.

2. The permitting process

2.1. The boundary between the permit processes.

New nuclear facilities must be authorised under both the Nuclear Activities Act

(1984:3) and the Environmental Code. Under the current system, a permit

application for a new nuclear facility must be submitted to the Swedish Radiation

Safety Authority, which prepares the case under the Nuclear Activities Act, and to

the Land and Environment Court which prepares the case under the

Environmental Code. The cases are then forwarded to the government, which

decides on the issue of permissibility under the Environmental Code and issues

permission under the Nuclear Activities Act. If the government decides to grant a

permit, the matter will return to the Land and Environment Court, which will decide

on the permit in accordance with the Environmental Code and any terms and

conditions of the permit. Both the application under the Nuclear Activities Act and

the application under the Environmental Code must include an environmental

impact assessment and must be preceded by a consultation pursuant to Chapter

6 of the Environmental Code. Figure 2 below illustrates an example of the issues

to be examined as part the Environmental Code review and the Nuclear Activities

Act review, as well as any issues overlapping between the two reviews.

8 (62)

Figure 2. Differences and overlaps between parallel review procedures under the Environmental Code and the

Nuclear Activities Act (Vattenfall).

2.2. Scope and definition of permit applications

Vattenfall intends to apply for a permit under Chapter 9 of the Environmental

Code for the development and operation of a new nuclear power plant with two or

more nuclear reactors with a combined electrical output of up to 2,800 MWe The

permit application will cover only the development and operation of the facility, not

the future decommissioning of the new nuclear power reactors.

The operation of a nuclear power plant generates conventional waste (non-

hazardous and hazardous waste) and nuclear waste, see also Section 3.3.4.

Nuclear waste will be managed and temporarily stored within the operational area

in preparation for, or pending, continued management and final disposal

elsewhere. The final disposal of such nuclear waste is not covered by the planned

operations.

Spent nuclear fuel will be managed and stored in fuel ponds within the operational

area before being transported to a dedicated interim storage site. Such interim

storage of nuclear fuel, as well as the final disposal thereof, is not covered by the

planned operations.

The planned operations are considered to be mainly covered by the following

provisions in the Environmental Assessment Regulations (2013:251):

• Chapter 21 Article 7 Permit requirement A and activity code 40.30 apply

to nuclear power reactors or other nuclear reactors.

• Chapter 21 Article 9 Permit requirement B and activity code 40.50-i

apply to combustion plants with a total rated heat input of 50 megawatts

or more but not more than 300 megawatts.

• Chapter 12 Article 32, Permit requirement B and activity code 24.32-i

apply to facilities for the production of non-metals, metal oxides or other

inorganic compounds by chemical or biological reaction on an industrial

scale up to 20 000 tonnes per calendar year.

9 (62)

• Chapter 29 Article 58 Permit requirement A and activity code 90.460

apply to the treatment of high-level radioactive waste, final disposal of

radioactive waste or storage of radioactive waste.

• Chapter 29 Article 59 Permit requirement A and activity code 90.470

apply to the processing, storage, final disposal or any other management

of spent nuclear fuel, nuclear waste or other radioactive waste in

accordance with the Act (1984:3) on Nuclear Activities (Nuclear Activities

Act) or the Radiation Protection Act (2018:396), if the management is not

subject to permit under Article 58.

Vattenfall also plans to apply for a permit under Chapter 11 of the Environmental

Code for the water operations that will be required for the development and

operation of the facility, including seawater abstraction for cooling water

purposes, the construction of facilities in water areas, groundwater abstraction,

the filling of ponds and water bodies in the area, re-infiltration and more.

This activity may require a permit under Chapter 7. Article 28 a of the

Environmental Code (referred to as “Natura 2000 permit”). Such a permit will be

granted provided that the activity is deemed to have a significant impact on the

nearby Natura 2000 site. Vattenfall will investigate the impact of the operations on

the nearby Natura 2000 site and the need for a Natura 2000 permit as part of the

application process. An application for a permit under the Cultural Environment

Act (1988:950) and an exemption from the Species Protection Regulations

(2007:845) are also expected to be required.

The Nuclear Activities Act requires a permit for the development, possession and

operation of a nuclear facility and for the management of nuclear material and

nuclear waste. A separate permit application under the Nuclear Activities Act will

be submitted to the Swedish Radiation Safety Authority and processed alongside

the Environmental Code review. The Nuclear Activities Act also lays down

requirements for the performance of a specific environmental assessment under

Chapter 6 of the Environmental Code. Vattenfall plans to produce a joint

environmental impact assessment for the reviews under both the Environmental

Code and the Nuclear Activities Act. This scoping consultation is a combined

consultation for the two reviews.

2.3. Related questions

A preliminary assessment shows that the planned operations are covered by the

Act (1999:381) on Measures to Prevent and Limit the Consequences of Major

Chemical Accidents and related delegated legislation (the Seveso legislation) in

view of the chemicals planned to be managed in the operations, see also Chapter

7.13.

The total rated output of the planned auxiliary power units means that the

operations are deemed to be subject to a permit requirement under Chapter 21,

Article 9 of the Environmental Assessment Regulations (activity code 40.50-i).

Planned production of sodium hypochlorite is also subject to a permit according to

Chapter 12, Section 32 of the Environmental Assessment Ordinance (activity

code 24.32-i). This also means that the operations constitute an industrial

emissions activity under Chapter 1, Article 2 of the Industrial Emissions

Regulations (2013:250), and that they are covered by said Regulations. Since the

10 (62)

operations are covered by the Industrial Emissions Directive, a status report must

be prepared and included in the application.

The planned auxiliary power units will each have an installed output of less than

15 MW, which means that the activity is not covered by the Large Combustion

Plants Regulations (2013:252) (cf. Articles 6 and 36 of the Regulations, stating

that installations below 15 MW should not be aggregated). Instead, in view of the

planned auxiliary power units, the activity is covered by the Medium Combustion

Plants Regulations (2018:471)

The operations will also be subject to the Radiation Protection Act (2018:396) and

the Accident Prevention Act (2003:778) and related regulations.

Large sections of the planned operational area are subject to zoning. As a result

of the planned operations, existing zoning plans will need to be revised and/or

replaced by one or more new zoning plans. The process of revising and/or

replacing existing zoning plans will take place separately and alongside the

forthcoming permitting process. In addition, a building permit is required for the

development of the operations under the Planning and Building Act (2010:900).

Areas in the Biskopshagen Nature Reserve will also be utilised for the operations

and will therefore need to be occupied.

3. Planned operations

This section provides preliminary and summary information on the planned

operations. Work is currently underway to investigate the technical and financial

conditions for the planned operations, which will form the basis for the detailed

design of the operations. Vattenfall intends to report further information about the

design of the operations, and prepare preliminary assessments of the impact of

the operations on human health and the environment, at a later stage of the

permit process.

The following section describes initially the development and erection phase,

followed by the characteristics of the nuclear reactors, how cooling water will be

supplied, the need for backup power, and the management of waste and spent

fuel. It also describes how control, monitoring and supervision of the planned

operations will be carried out.

3.1. Development

The development of the planned operations will start with ground preparation

measures to create a level and stable foundation with the correct height. This

work is estimated to take approximately two years and will involve blasting the

bedrock, building cooling water structures, filling and levelling the area, etc. The

ground level varies relatively widely across the area, from approximately 4–30

metres above sea level. The levelled ground level on which the plant will be

situated takes into account normal water level variations resulting from prevailing

weather patterns and expected sea level rises caused by climate change. It is

likely that the ground level for the plant will be somewhere between four and six

metres above sea level.

11 (62)

The soil and rock masses generated during the construction phase will primarily

be utilised within the project, or transported to nearby reception facilities where

the masses will primarily be reused, then recycled and, as a last resort, disposed

of. Rock crushing may take place on site. After ground preparation, connections

to water and electricity will be provided in the construction area.

Construction work, consisting of laying the foundations and erecting buildings

such as reactor buildings and turbine buildings will then begin. Finally, system

components will be supplied. The erection and installation work for each nuclear

reactor is estimated to take approximately four to six years. The small modular

reactors, described in section 3.2, each take a shorter time to build and

commission than the large reactors.

Vattenfall will also build its own workshops for maintenance and servicing, new

storage and warehouse buildings, and premises for other support activities that

may be needed, such as emergency services and security. Coordination with

Ringhals AB regarding emergency preparedness may take place in cases where

it is possible and considered appropriate.

Construction materials and components will be transported to the site by lorry or

by ship. During the construction period, temporary storage and assembly areas

will be needed within and adjacent to the construction site. The exact location of

the temporary storage and assembly areas has not yet been decided, but these

areas may need to be located in neighbouring local authority areas. Roads and

storage areas will be paved or otherwise hardened.

Additional space in the immediate area is needed for, for example, parking

spaces, crew sheds and temporary accommodation for the contractors hired

during construction. Up to 10,000–12,000 people may be employed during the

construction phase if large reactors are built.

Intake and discharge of cooling water will take place via existing or newly

constructed infrastructure. Work in and adjacent to the water will, depending on

needs and conditions, be carried out through blasting, excavation, dredging, filling

and/or casting or similar measures.

Construction work will continue every day, around the clock. The construction site

will be fenced and floodlit.

The construction, installation and commissioning of the planned operations are

estimated to take approximately 10 years. Construction for ground preparation

work is expected to begin in the second half of the 2020s, provided that the

necessary permits have been issued and investment decisions made.

Construction work will be carried out in accordance with current legislation, and

Vattenfall will work to minimise disruption.

3.2. Nuclear reactors

Nuclear reactors constitute the central part of the planned operations. Vattenfall

plans to build and operate two large nuclear reactors, or three to five small

modular nuclear reactors, with a combined electrical output of up to 2,800 MWe

(equivalent to no more than 8,400 MW heat output).

12 (62)

Each nuclear reactor will consist of a reactor and a turbine section. The nuclear

reactors will also be independent of each other, but will share services such as

seawater intake, maintenance workshops, waste management, etc. The operation

of the nuclear reactors will be managed by an on-site operating organisation.

Operation includes recurring fuel replacement. .

3.2.1. Evaluated reactor types

The nuclear reactors will be based on proven light water technology and will incorporate the latest developments in terms of safety and performance. Light water technology is available today as large reactors and small modular reactors. Vattenfall has evaluated both of these designs and is continuing to investigate which type of reactor and how many reactors will be built as part of the planned operations. The suppliers of light water technology that Vattenfall has deemed suitable for the planned operations offer large reactors, in the form of pressurised water reactors, with an approximate electrical output of 1,200–1,400 MWe and small modular reactors, in the form of boiling and pressurised water reactors, with an approximate output of 300–500 MWe. Unlike small modular reactors, large reactors are in operation around the world today, and there is experience of how these are designed and built. In addition to the lower power, small modular reactors are characterised by being designed with a focus on modularity, scalability and simplicity, which allows them to be mass-produced and be more cost-effective than traditional large reactors. What the evaluated reactor types have in common is that they, regardless of size, are based on reliable, proven technology but with further modernisations. Modern reactors feature simplified but robust and reliable design solutions and utilise standardised components to a greater extent compared to existing nuclear power reactors. Operating characteristics have also been improved through, in particular, longer estimated operating time, higher availability and the possibility of flexible operating cycles. Further innovations that occur among the evaluated reactor types include, for example, the possibility of placing reactor buildings partially underground, which increases resistance to natural phenomena. The evaluated reactor types also use passive safety systems, to varying degrees, for emergency cooling of the reactor and containment, reducing the need for separate motive power, such as electricity, to operate.

3.2.2. Function and technical characteristics

The nuclear reactors considered for the planned operations will be based on light water technology, meaning that enriched uranium is used as fuel and that normal water is used as coolant and moderator. Light water technology comes in two designs: boiling water or pressurised water reactors. The basic principle is the same for both. Nuclear fission takes place in the reactor. A neutron is sent towards a uranium atom whose nucleus splits and new neutrons are released. These can in turn split more uranium nuclei and a chain reaction occurs. Nuclear fission releases energy that is used to evaporate water. The steam generated can be used in a turbine plant to generate electricity. In a boiling water reactor (BWR), the uranium fuel is split in the reactor vessel, which generates heat. The control rods regulate the power depending on the position and water flow. The heat generated from nuclear fission causes water to

13 (62)

boil and steam to form. The steam is directed to the turbine plant, which causes the turbine to rotate. A generator is connected to the turbine shaft and electrical energy is generated during rotation. Using cooling water from the sea, the steam is cooled down and converted into water in the condenser. The water is pumped back into the reactor to cool the fuel. Cooling water from the sea is released via a tunnel back into the sea. The process is illustrated in Figure 3.

Figure 3. Schematic diagram of a boiling water reactor. (Ringhals AB).

Reaktortank – Reactor tank

Turbin – Turbine

Generator – Generator

Havsvatten – Seawater

Kondensor – Condenser

In a pressurised water reactor (PWR) there are two cooling water circuits; a primary circuit and a secondary circuit. The control rods regulate the power depending on the position and water flow. The water in the primary circuit is heated by nuclear fission in the reactor vessel but is prevented from boiling by keeping the pressure high. The water from the primary circuit heats the water in the secondary circuit in a heat exchanger, also called a steam generator. The water in the secondary circuit boils and the steam formed is directed to one or more turbines. Low-pressure steam from the turbine is then fed to the condenser for cooling using cooling water from the sea, after which the condensate formed is pumped back to the steam generator. The water in the primary circuit is pumped back to cool the core. Cooling water from the sea is released via a discharge tunnel back into the sea. The process is illustrated in Figure 4.

14 (62)

Figure 4. Schematic diagram of a pressurised water reactor. (Ringhals AB).

Vattenfall is investigating possible reactor types, i.e. both large reactors and small modular ones. Table 1 shows the overall technical characteristics of the planned operations based on the reactor types being investigated.

3.2.3. Nuclear safety and radiation protection

Regardless of which type of nuclear power reactor Vattenfall chooses, the planned operations will be conducted in such a way as to ensure a high level of safety and compliance with legal requirements. The safety of a nuclear reactor is based on what is known as the defence-in- depth principle, which aims to eliminate the harmful effects of ionising radiation. These issues are governed by the Nuclear Activities Act and the Radiation Protection Act, as well as regulations issued by the Swedish Radiation Safety Authority. The defence-in-depth principle applies several successive technical, organisational and manual measures to minimise the discharge of radioactive effluents into the environment and the harmful effects of radiation. Defence in depth, as defined by the Swedish Radiation Safety Authority (SSM), is divided into five levels for the purposes of:

• Preventing operational disruptions and other errors through quality design, stable operation and adapted maintenance.

• Detecting and monitoring operational disturbances to ensure they do not result in accidents and that the nuclear reactor can be restored to normal operation.

• Minimising the effects of accidents and preventing extensive fuel damage.

• Ensuring that radioactive releases caused by accidents involving extensive fuel damage are as low as reasonably achievable.

• Mitigating the effects of radioactive discharges. The design of the nuclear reactor and the organisation of its operations help to build defence-in-depth and combine to maintain radiological safety and radiation protection. The nuclear reactor is designed with several physical barriers, which are included as part of defence in depth to prevent or delay the discharge of radioactive effluents into the environment. The multi-barrier principle means that if one barrier fails, the next one will come into play. There are four physical barriers around the nuclear fuel in the core:

• The fuel (which binds most of the radioactive effluents).

• The fuel cladding tube.

• The reactor vessel with associated piping system.

16 (62)

• The reactor containment The effectiveness of the physical barriers is ensured by the safety features of the nuclear reactor, which include : reactivity checks (e.g., the ability to quickly shut down the reactor), removal of heat from the reactor and fuel storage, and containment of radioactive material (checks of planned radioactive discharges and limitations of accidental radioactive releases). The safety features are present to varying degrees in the defence-in-depth level They are ensured, in particular, by systems and components manufactured and tested against strict quality standards. The capacity of the nuclear reactor’s barriers and safety features is verified by means of a safety analysis and is reported by the permit holder in a radiation safety report. Said report also details effects in the form of discharges into the environment during normal operation, operational disruptions and accidents. In addition to the barriers above, there are other design safeguards that prevent and limit exposure to ionising radiation. This is achieved by the building being equipped with thick radiation shields made of concrete or lead. In addition, physical protection is installed to protect against theft and other unauthorised handling of nuclear material and other radioactive effluents. The physical protection also prevents access to the facility by unauthorised persons. The operations will be designed based on current requirements. Any effects regarding ionising radiation during normal operation and unexpected events will be described and assessed in a future environmental impact assessment.

3.3. Support activities

3.3.1. Water activities

The plant will require a cooling water intake of no more than 120 m3 of seawater

per second. Plans are to deploy the intake in the northern section of the planned

operational area.

Cooling water intake will be made possible through surface water intake, deep

water intake or a combination of surface and deep water intake. To prevent large

objects such as driftwood and ice from being brought in from the sea through

surface water intake, a foam barrier extending a little below the surface of the

water or another solution with the same function will be built at the intake point. At

a surface water intake, the water temperature varies over the year from

approximately 0ºC to 25ºC, which affects the efficiency of the plant. At a deep

water intake, the water temperature is relatively stable throughout the year. For a

deep water intake, either a blasted/drilled tunnel or bottom-laid pipes are required.

The intake will be supported by equipment that allows water to be supplied from

the bottom via an intake caisson.

Regardless of the type of water intake, the cooling water will be channelled into a

basin and then filtered in several stages to separate unwanted material such as

seaweed, fish, jellyfish, etc. Large material will be separated using a cleaning

screen or similar, while smaller particles will be separated using a fine screen

followed by a screening machine. The water will then be channelled via an

underground tunnel or via an open cooling water channel to the turbine building

17 (62)

used to condense steam. The waste that accumulates in grids and screening

machines will be collected in chutes and flushed out with seawater. As far as

possible, the flushing water will be returned to the sea. However, large amounts

of sewage tend to accumulate periodically, mainly during summer/autumn or

during storms. To prevent it from reinfiltrating the intake building, it may be

necessary to drain the sewage into special basins. Chlorine or an equivalent

agent will also be added to reduce the growth of marine organisms in the cooling

water.

Used cooling water will be returned to the recipient using existing infrastructure in

the area or newly built tunnels. Cooling water can be distributed via open

channels or blasted tunnels. The exact location and design of the discharge

system is currently being investigated.

Groundwater will be drained during the construction and operational phases. The

extent to which groundwater will be diverted is currently being investigated. Small

areas of water within the operational area will be filled in. Work in water areas will

also be required for the development of the operations, including for any new

plant components required for water extraction and discharge. Groundwater and

stormwater, for example, will be reinfiltrated.

3.3.2. Backup power

To ensure electrical power to the reactors and other prioritised systems if the

power supply is cut off, backup power systems in the form of, for example,

batteries, diesel/gasoline/HVO generators or gas turbines will be installed. The

backup power systems will be tested regularly. They will have an output of up to

approximately 10 MWe each and a total rated input power of approximately 20–

110 MW.

3.3.3. Sodium hypochlorite production

Hypochlorite is a possible operating chemical that could be produced at the plant

through seawater electrolysis.

Hypochlorite can be used to reduce the growth of marine organisms in cooling

water systems to ensure a continuous and adequate supply of cooling water and

thereby prevent disruptions to the process.

3.3.4. Waste management

Waste management in planned operations will be based on the EU’s waste

hierarchy, which has been transposed mainly through Chapter 15 of the

Environmental Code. In line with the order of priority laid down by EU waste

legislation, waste should initially be prevented, secondly reused, thirdly recycled,

fourthly used to recover energy and finally landfilled. Any waste that continues to

be generated by the operations after preventive measures have been put in place

will be managed and classified based on established procedures.

Construction is expected to generate large quantities of packaging waste, etc.,

which will be sorted for further processing by authorised recipients. For

18 (62)

management of soil and rock masses, see chapter 3.1. A mass management plan

will be developed.

Both hazardous and non-hazardous waste that is not radioactive will be managed

and temporarily stored in buildings or on adapted areas within the operational

area. Waste will then be disposed of by an approved transporter and recipient.

During the operation of the nuclear power plant, radioactive waste will be

generated in addition to conventional waste. A nuclear power plant is divided into

different zones based on the risk of ionising radiation. Areas where there is a risk

of ionising radiation are called controlled areas. Any waste that is generated

outside a controlled area constitutes conventional waste. Conventional waste may

be both non-hazardous and hazardous waste and will be managed in accordance

with current regulations and delivered to transporters and recipients who hold the

necessary permits.

All waste generated within a controlled area is classified as radioactive waste and

is managed as if it were contaminated. Measurements are made of the waste’s

radioactivity, which forms the basis for its classification. Radioactive waste is

classified based on two criteria: dose rate and half-life. Waste that is deemed to

be reclassifiable is sorted out, decontaminated, if necessary, and measured for

inspection purposes. Clearance means that the rules stemming from the

Radiation Protection Act do not need to be applied, since the risks of radioactive

contamination are so small that they can be considered negligible. If the

contamination level post-measurement is below the limit values defined by the

Swedish Radiation Safety Authority, the material may be cleared and then

managed as conventional waste. For cleared conventional waste from operations,

the focus is on waste being primarily prevented, secondarily reused, thirdly

recycled, fourthly used for energy recovery and finally landfilled.

Radioactive waste is categorised based on its activity content and can be roughly

divided into four groups: very low-level short-lived waste, short-lived low- and

intermediate-level waste, long-lived low- and intermediate-level waste and high-

level waste. High-level waste consists of spent nuclear fuel only when it has been

placed in a repository.3 why this is not covered by planned operations.

3.3.4.1. Very low-level short-lived waste

The radiation intensity in this waste is so low that after sorting it can be deposited

in an external landfill, or alternatively managed by, for example, melting or

combustion at another facility. The waste in this group consists, for example, of

compactable waste (paper, wood, plastic, fabric, etc.) , non-compactable waste

(concrete, construction waste, pipes, sheet metal, scrap iron, cables, etc.) and ion

exchange resins and sludge.

3.3.4.2. Short-lived low- and intermediate-level waste

Short-lived low- and intermediate-level solid waste consists primarily of waste

from maintenance work and replaced components as well as rags, gloves,

protective equipment and disposable items. These types of waste are currently

handled at existing nuclear power plants primarily through compaction or

3 see Article 2, point 3 of the Nuclear Engineering Act

19 (62)

segmentation to reduce volume and then packaged in approved packaging. A

certain portion of the short-lived low-level waste can also be handled by melting

or combustion at another facility before being packed in suitable packaging. For

short-lived intermediate-level waste, there are requirements that the waste must

be encapsulated.

The waste is temporarily stored after being packed in suitable packaging for a

period of time before being sent in special transport canisters to a repository for

short-lived radioactive waste.

Liquid-borne short-lived low- and intermediate-level waste that may result from

the purification of process water consists primarily of ion-exchange resins,

evaporator concentrates and sludge. Ion-exchange resins and sludge are

pumped into tanks where they are stored pending further processing. Wastewater

is evaporated and the concentrate collected in tanks pending further processing,

but other alternative methods of concentrating liquid waste may also become

relevant. The waste is then stabilised in designated packaging to enable final

disposal at another facility.

3.3.4.3. Long-lived low- and intermediate-level waste

Some long-lived low- and intermediate-level waste is generated, mainly during

decommissioning, but components close to the reactor may also become

neutron-induced and need to be managed as long-lived waste during a

replacement, for example.

The waste will temporarily be stored within the operational area pending further

processing and final disposal.

3.4. Checks and monitoring

3.4.1. Checks pursuant to the Environmental Code and Seveso

legislation

Under the Environmental Code, the responsibility for protecting human health and

the environment from damage and inconvenience caused by an environmentally

hazardous activity lies with the party conducting the activity. This means that the

operator must carry out specified checks and that a regulatory authority must

supervise such checks. In addition, an activity that is subject to a permit under

Chapter 9 or Chapter 11 of the Environmental Code is covered by the Operators

(Self-Monitoring) Regulations (1998:901).

Activities covered by the Seveso legislation must, in accordance with Article 10 of

the Seveso Act, prepare a safety report with related documents in accordance

with Article 9 of the Seveso Regulations.

The County Administrative Board will be the regulatory authority for

environmentally hazardous activities, Seveso activities and water activities.

Vattenfall will draw up a proposal for a self-monitoring programme for the external

environment. The programme will describe how the environmental impact of the

20 (62)

activity, and the conditions imposed by the Property and Environmental Affairs

Chamber (PEAC), will be monitored. Checks cover both the construction period

and the operational period and must be communicated to the regulatory authority

(the County Administrative Board of Halland) before they are performed.

3.4.2. Checks pursuant to the Nuclear Activities Act and the

Radiation Protection Act

Anyone who conducts nuclear activities is responsible for safety and radiation

protection and must carry out specified checks. The Swedish Radiation Safety

Authority monitors this process.

Vattenfall will draw up a programme for local environmental monitoring that will

include, in particular, procedures for monitoring discharges of radioactive effluents

into air and water and the monitoring of radioactive effluents in the environment.

Radiological consequences for the environment and people in the vicinity of the

nuclear power plant as a result of these discharges will be evaluated.

Sub-programmes that concern monitoring of radioactive effluents in the

environment must be approved by the Swedish Radiation Safety Authority before

being applied. The Swedish Radiation Safety Authority also conducts its own

random sample examinations and monitors the results.

4. Related activities

The following section describes activities that relate to the planned operations, but

are not covered by it.

4.1. Electrical system

The planned operations will produce electricity for the Swedish national grid. The

connection points to the existing 400 kV switchyard are located approximately 1.5

km east of the planned operational area.

Additional switchgear will be required to connect the operations to the national

grid. Switchgear will be built near the plant and connected to outgoing lines that in

turn connect to the main grid at the existing 400 kV switchgear facility east of the

Ringhals Nuclear Power Plant. The facility is connected to the main grid through

underground cables, overhead lines or a combination of these.

In addition to connection to the 400 kV grid for the output of electrical power, the

facility may require connection to the 132 kV grid for independent input. The line

will be laid underground or via overhead lines from nearby 132 kV switchyards.

Switchgear and connecting lines are facilities subject to a concession under the

Electricity Act (1997:857).

21 (62)

4.2. External management of spent nuclear fuel and

nuclear waste

Spent nuclear fuel will temporarily be stored in the facility’s fuel pools, while low-

and intermediate-level nuclear waste will be stored in planned operations on an

interim basis, in accordance with the criteria set out in section 3.3.4. Subsequent

management of nuclear waste and spent nuclear fuel, such as interim storage by

an external party and final disposal, is not covered by the planned operations and

will therefore not be subject to impact assessment as part of the permit

applications. However, the principles for interim storage and final disposal will be

described in brief in the application documents.

Under the Nuclear Activities Act and the Radiation Protection Act, Swedish

nuclear power companies are required to manage their radioactive waste. Today,

this is done by Svensk Kärnbränslehantering AB (SKB), a company owned by

Sweden’s nuclear power companies. Vattenfall will follow the rules in place to

ensure that resources are allocated for the disposal of radioactive waste

generated. Holders of permits for nuclear reactors are required to pay a fee to the

Nuclear Waste Fund, which is managed by the Swedish National Debt Office. The

funds in this fund will cover the cost of nuclear waste disposal, among other

costs. In addition, companies provide financial collateral to manage a possible

situation where the fund’s funds are not sufficient. In the autumn of 2023, the

government appointed an inquiry group to analyse, in particular, the need for any

changes to the system used to manage nuclear waste and spent nuclear fuel

from new nuclear power (Dir. 2023:155). The inquiry group will present proposals

in that regard on August 29, 2025. The government has also commissioned the

Swedish National Debt Office in the spring of 2024 to investigate the need for any

changes to regulations governing the financing of the disposal of nuclear waste

when new nuclear reactors are being developed. Particular importance should be

placed on ensuring that the regulations do not prevent reactors on new sites, new

actors or actors with waste from new reactor types from establishing themselves.

The group has been tasked with preparing a report and submitting it by 31 August

2025 at the latest. Vattenfall will follow the inquiry group’s work.

Currently, the existing system for the disposal of radioactive waste and spent

nuclear fuel consists of the Central Interim Storage Facility for Spent Nuclear Fuel

(Clab) in Oskarshamn, the Repository for Short-Lived Radioactive Waste (SFR) in

Forsmark and related transport systems. There are plans to add more facilities to

the current system, including a facility for final repository of spent nuclear fuel and

a repository for long-lived waste (SFL). In addition, a new encapsulation facility

will be built in the vicinity of Clab. Clab, along with the encapsulation facility, will

constitute Clink. The existing system for managing radioactive waste and spent

nuclear fuel, as well as planned facilities, is shown in Figure 5.

22 (62)

Figure 5. The existing system for managing radioactive waste and spent nuclear fuel. The blue rock chambers in

SFR, the encapsulation facility adjacent to Clab and SFL, and the final repository for spent nuclear fuel are facilities

that have yet to be built (Svensk Kärnbränslehantering AB).

The planned operations will be aligned with the existing system for managing

radioactive waste and spent nuclear fuel, but new facilities with their own permits

will need to be established. However, this is not included in the planned

operations.

4.3. Decommissioning

The lifespan of planned reactors is estimated at 60–80 years. When electricity

generation ceases, decommissioning work begins. Decommissioning refers to

everything from permanently shutting down the reactor, removal of spent fuel,

phased demolition, cleaning, storage and removal of demolition materials and

radioactive waste to restoration of the area. The operator is required to have a

preliminary plan for decommissioning, and such a plan will be developed by

Vattenfall. The purpose of the plan is to ensure that radiation protection aspects

such as radiation doses, discharges of radioactive effluents and waste quantities

are taken into account during decommissioning.

Decommissioning a nuclear reactor is an activity that in itself requires a permit

under the Environmental Code. This means that the operations sought do not

include future decommisioningclosure. When relevant, this matter will be

managed separately. Decommissioning will therefore not be included in impact

assessments for the planned operations, but will be described in brief in the

application documents.

5. Alternative

5.1. Zero alternative

An environmental impact assessment must, among other things, include a

description of how the current state of the environment is expected to change in

the future if the intended activity does not take place, a so-called zero alternative.

The purpose of reporting the zero alternative is to provide a basis for evaluating

what change the activity or measure entails from an environmental point of view.

23 (62)

The zero alternative in this case consists of the planned operations not being

established at the site.

One consequence of the operation not coming to fruition is that the planned

addition of predictable and fossil-free electricity production from the operation in

the mid-2030s will not occur. This means an increased risk that the production of

electricity in Sweden will not be sufficient to meet the increased demand that is

expected to occur in the coming decades as a result of, among other things,

electrification and the green transition of industry.

5.2. Alternative localisation

Under the Environmental Code's localisation principle (Chapter 2) Article 6 states

that for an activity or measure that uses a land or water area, a location must be

chosen that is suitable with a view to achieving the purpose with the least

interference and inconvenience to human health and the environment. Under

Article 17 of the Environmental Assessment Regulations, the environmental

impact assessment must, among other things, contain information about possible

alternative locations and the reasons why the selected location has been chosen

over other alternatives.

A location investigation has been carried out at an early stage to identify a

suitable location for the facility, taking into account that the purpose of the

operation can be achieved with the least interference and inconvenience to

human health and the environment, in accordance with the general rules of

consideration in the Environmental Code. Balances have also been made

between conflicting interests in accordance with the Planning and Building Act

(2010:900).

The location study investigated possible locations for the planned operations

based on several criteria, including space requirements, access to infrastructure

and electricity grids, and proximity to the coast. The location alternatives that met

the basic criteria were further evaluated in an in-depth investigation.

In the in-depth investigation, the location alternatives were evaluated based on,

among other things, how much untouched land would need to be used by the

operation, the impact on national interests and other protected natural areas,

distance to housing, and more. Based on a balanced assessment of all relevant

aspects, a location on the Värö Peninsula, directly west and southwest of the

Ringhals Nuclear Power Plant, was deemed to be the most suitable, taking into

account that the purpose should be achieved with the least interference and

inconvenience to human health and the environment.

The completed location investigation will be described in more detail in the

upcoming environmental impact assessment.

5.3. Alternative design

Under Chapter 2, Article 3 of the Environmental Code, the best possible

technology must be used to prevent an activity from causing damage or

inconvenience to human health and the environment. Evaluation of various

suppliers for the nuclear facility is underway and the upcoming environmental

24 (62)

impact assessment will contain a report on alternative technologies for and

designs of the planned operations. The presentation of alternative technologies

will focus on the design of necessary facilities and measures that are relevant

based on environmental impact.

The planned operations are considered to be covered by Chapter 21, Article 9 of

the Environmental Assessment Regulations (activity code 40.50-i). The operation

is therefore also considered to be covered by the Industrial Emissions

Regulations (2013:250). For combustion plants to be covered by the conclusions

on best available techniques for large combustion plants (BAT-LCP), the criterion

stated is that the total rated input power must be at least 50 MW. When assessing

the total power, a total of installed input power shall be calculated for all

combustion units that have an installed input power of at least 15 MW. Planned

reserve power units will each have an installed input power of less than 15 MW,

which means that the operation is not considered to be covered by BAT-LCP .

Instead, the planned operations are covered by the Regulations (2018:471) on

Medium Combustion Plants (FMF), which implement Directive 2015/2193/EU on

the limitation of emissions of certain pollutants into the air from medium

combustion plants (MCP Directive).

The activity is also considered to be covered by BREF4 -documents Energy

Efficiency and Industrial Cooling Systems. The BREF document Energy Efficiency

was adopted by the European Commission in February 2009. The document is a

cross-cutting document that covers energy efficiency in several different industrial

sectors. The aim is to provide general indications on energy efficiency

technologies that can be considered as a suitable reference point. The BREF

document Industrial Cooling Systems was adopted by the European Commission

in December 2001. The document is a cross-cutting document that covers the

use of cooling systems in several different industrial sectors. The document only

covers cooling systems that use air and/or water for heat exchange.

Any applicable and relevant parts of the conclusions on best available techniques

under the Industrial Emissions Directive (2010/75/EU) will be reported in the

upcoming application and environmental impact assessment.

6. Environmental conditions

6.1. Environment

The operations are planned to be located within about ten properties, directly west and southwest of the Ringhals Nuclear Power Plant, on the Värö Peninsula in the Varberg Local Authority Area. The properties currently include permanent residences, holiday homes and agricultural properties. The majority of the properties are owned by Vattenfall and are rented or leased to private individuals and the Swedish University of Agricultural Sciences (SLU). The planned operational area and its surroundings are shown in Figure 6. The operational area is assessed to be larger than the area required for future operation of nuclear activities. In addition, temporary storage and assembly sites outside the operating area may be needed during the construction period.

25 (62)

Bua and Väröbacka are the closest urban areas located just over 1 km and

approximately 4.5 km from the planned location, respectively. The towns of

Skällåkra and Gloppe are located approximately 1-1.5 km from the planned

location.

On the other side of Båtafjorden in Bua, about 2 km south, there is a preschool

and school. There is also a landscaped playground and sports field. In

Limabacka, about 5 km to the southeast, there is a retirement home.

In Båtafjorden is Videbergshamn, which consists of a recreational harbour and a

harbour belonging to Ringhals AB. The part of the port that belongs to Ringhals

AB is used primarily for the importation of fuel and the exportation of radioactive

waste, but is also used for other types of goods and by other companies. There is

a public road between the Ringhals Nuclear Power Plant and the harbour.

Traffic in the local area consists mostly of transport to and from the Ringhals

Nuclear Power Plant and the neighbouring community of Bua. The nearest major

road is the E6 between Malmö and Gothenburg, located approximately 6 km east

of the planned operation. Road 848, as well as road 850 and road 847, run from

road E6 to the planned operational area.

6.2. Planning document

6.2.1. Comprehensive plan

The planned area of operation is located within an area that in the

Comprehensive Plan for the Varberg Local Authority (adopted on 15.06.2010), is

designated as “Ringhals Nuclear Power Plant and Its Surroundings”5 . According

to the master plan, in the surrounding areas of Lingome, western Båtafjorden and

northern Biskopshagen, very strict restrictions must be observed when examining

buildings and other measures with regard to the nearby nuclear power plant. The

County Administrative Board shall therefore, taking into account the protection

area around the Ringhals Nuclear Power Plant and the health and safety of the

residents, specifically examine issues regarding building permits and prior

approvals in these areas. Figure 7 shows part of the land and water use map for

the current comprehensive plan.

Varberg Local Authority adopted an in-depth master plan for the Northern Coast

on 14.02..6 which covers the area of the planned operations. The goal of the

detailed master plan is long-term sustainable development and to enable a good

living environment, a good business environment, and to protect and make

accessible natural and recreational areas. The detailed master plan includes a

plan proposal with specifically identified development areas. The closest

designated development area from the planned area of operation is Bua.

Work is underway to develop a new master plan for Varberg Local Authority that

will extend until 2050.

6.2.2. Zoning plans

Large parts of the planned operational area are covered by the current zoning

plan for Ringhals (VÄ56). Parts of the coastal area covered by VÄ56 were

updated with a new zoning plan in 2010 to enable the establishment of wind

power (VÄ94). The zoning plans are presented in Figure 8 below.

adopted by the City Council on 14.02.2017.

28 (62)

Figure 8. Existing zoned areas (Varberg Local Authority Area).

A detailed planning process has been initiated in parallel with the environmental

assessment process to amend existing zoning plans and/or prepare one or more

new detailed plans to enable the planned operations.

6.3. National interests

The Environmental Code contains provisions on how land and water should be protected and used. Certain areas are classified as being of national interest, either to protect the areas from exploitation or to ensure that they can be used for a specific, important purpose. Within and in the immediate area surrounding the planned area of operation, there are national interests covered by Chapters 3 and 4 of the Environmental Code, see Figure 9 and Table 2.

29 (62)

Figure 9. Identified national interests within and in the immediate area surrounding planned operations. National

interests covering the entire area shown have been excluded from the map. National interest in active outdoor

recreation and highly exploited coasts is therefore not visible in the figure. Areas of national interest for energy

production and energy distribution are classified and the extent of these areas is therefore not shown in the figure.

6.4. Geology and soil conditions

The bedrock in and around the planned operational area consists mainly of

gneisses with a dominant granitic to granodiorite composition. The rock quality is

classified as consistently good.7 . The soil depth within the area varies between

0–15 metres with the deepest soil depths in the southern part of the area. The

soils consist of both clay and organic soils as well as friction soils of sand and

moraine.

The planned area of operation is not located within any designated risk area for

landslides, rock falls or erosion.8 . A number of minor landslide caution areas

along certain stretches of coast in the immediate vicinity of the planned

operational area are identified in the Geological Survey of Sweden (SGU) map

service. A smaller such area also fits on the coast within the northern part of the

planned operational area. These are areas where there may be conditions for

landslides in clay and silt soil.9 . The stability of the soil will be further investigated

as part of the process of preparing application documents and any risks

associated with this will be managed during construction of the facility.

Historical photographs show that agricultural activities have primarily been carried

out within the planned area of operation. The County Administrative Board's map

of suspected and confirmed contaminated areas (EBH map) shows that in

connection with the planned operational area there are two areas classified in risk

class 3 (moderate risk), see Figure 10. These areas are called “Industrial landfills”

and “Harbours – recreational marinas, boat parking areas”, respectively. In

addition, there is an unexplored area called "Wastewater Treatment Plant"10 .

6.5. Hydrology

The Värö Peninsula borders two surface water bodies, the Vändelsö Archipelago

(SE571720-120640) and the North Central Halland Coastal Waters (SE570000-

120701). Both water bodies are classified as having a moderate ecological status,

33 (62)

and they do not have a good chemical status. The impact on relevant quality

factors for the status classification will be reported in the application.

Within the planned operational area there are a number of smaller water bodies

and wetlands. In Varberg Local Authority’s Nature Conservation Programme,

which is used as a basis for community planning and nature conservation work, a

wetland area situated northeast of Biskopshagen Nature Reserve is mentioned.11

The wetland area overlaps the planned operational area.

There is no identified groundwater body within the planned operational area.

According to SGU's mapping service, the nearest reported well/individual water

source in Skällåkra is approximately 1 km from the planned operational area.12 .

6.6. Natural values

There are a number of designated areas of nature worthy of protection in the

vicinity of the planned operational area, see Figure 11 and Table 3.

6.7. Protected species

On the Värö Peninsula, species that are protected under the Species Protection

Regulations have been observed. Including vascular plants, amphibians,

mammals, reptiles, birds and insects.

Vattenfall will conduct a number of species inventories and carry out in-depth

investigations, see section 8.3, to assess the potential impact of operations on

these (and other) species and whether the operations require an exemption from

the Species Protection Regulations. The investigations will be included in the

application documents.

6.8. Cultural heritage

Within the planned area of operation, a number of ancient ruins and other cultural

artefacts, including stone settings and settlements, that may be affected have

been identified, see Figure 12. There are also several ancient ruins and other

cultural artefacts within the Biskopshagen Nature Reserve.13 .

Ancient ruins are traces of abandoned human activity that occurred before the

year 1850. All ancient ruins, even those that are not known, are protected under

the Cultural Environment Act. Cultural historical artefacts also include traces of

human activity that occurred during and after 1850. Other cultural and historical

artefacts do not have the same protection as an ancient monument, but

consideration and care must be shown.

Varberg Local Authority’s Cultural Environment Programme from 2016 identifies

important cultural environments within the local authority’s area. The cultural

environment programme shows that the Ringhals area has cultural and historical

values from a social, industrial and architectural historical perspective, among

other things. Bua village and the Vendel Islands are also designated as important

cultural environments.14 .

14 Cultural Environment Programme for Varberg Local Authority (2017).

37 (62)

There is no national interest in cultural environment protection in the vicinity of the

planned operations. The nearest, Nidingens Fyrplats, is over a mile north of the

business.

6.9. Landscape, outdoor life and recreation

The planned operations will use land areas that were previously partially

undeveloped. The area for planned operations consists of open land, with

mountains in the northern part of the area and a more open agricultural landscape

with housing in the southern part. There are also areas of deciduous and pine

forests, often in mountainous terrain, in the landscape. The height above sea

level varies greatly within the area. The areas with agricultural land are located at

approximately 2–20 meters above sea level, while the mountain peaks reach 30

metres above sea level in some places.

West of the planned operational area lies Biskopshagen Nature Reserve. The

nature reserve has natural pastures in the southern part and drier and nutrient-

poor rocky areas (heather landscapes) in the northern parts. In the depressions,

there are wetlands, and in areas close to the shore, there are shingle fields, rocky

outcrops of shale gneiss and various smaller water-filled depressions, so-called

rock pools.

Directly east of the planned operational area has been the Ringhals Nuclear

Power Plant since the 1970s. The power plant area is around 100 hectares in size

with buildings of varying heights.

The coastal area of North Halland is a recreational area for residents and tourists.

There are good opportunities for swimming, fishing, outdoor activities and nature

experiences. The entire area of operation is within the National Interest for

Outdoor Recreation. The national interest extends from the border with Skåne in

the south to Gothenburg in the north.

7. Expected environmental impacts

Chapter 6 of the Environmental Code states that environmental impacts mean

direct or indirect effects that are positive or negative, temporary or permanent,

cumulative or non-cumulative and that arise in the short, medium or long term on

the environment or human health. Environmental impacts are not limited

geographically; they can occur both in the immediate area and far away, and

within and outside Sweden's borders.

The following chapter presents preliminary environmental impacts resulting from

the construction and operation of the planned operations. The descriptions are

based on the different alternatives being considered and preliminary

environmental effects are described for the alternative that generates the greatest

need for space or the greatest environmental impact. Estimates for transports

given in section 7.6 below are based on rough estimates and may be adjusted

when more information is obtained.

38 (62)

7.1. Land use

7.1.1. During construction

Planned operations require a larger land area during construction than the land

area required for the operation of the facility. In addition, temporary storage and

assembly sites outside the operational area may be utilised during the

construction period. These may be located in the immediate area or in

neighbouring local authorities. Most of the temporary storage and assembly areas

will be restored after the construction period.

During all earthworks, special precautions will be taken in the event that

contaminated materials are encountered. Contaminated materials will be handled

appropriately in collaboration with the regulatory authority in accordance with the

Environmental Code.

7.1.2. During operation

The operation is estimated to have a lifespan of 60–80 years. Neither during this

time nor during the subsequent decommissioning will the land be able to be used

for other purposes.

7.2. Natural and cultural environment

7.2.1. During construction

The planned operations will take place in part of the Biskopshagen Nature

Reserve. A natural value inventory covering the current land area will be carried

out, and the issue of utilising the nature reserve will be investigated further. A

process to revoke the nature reserve has been initiated at the County

Administrative Board. Vattenfall will strive to minimise the impact on biodiversity

and is investigating the possibility of compensation.

Possible disturbances during the construction period include noise, dust,

vibrations and light. If the activity is assessed to have a significant impact on the

environment in the nearby Natura 2000 site Båtafjorden, a permit is required in

accordance with Chapter 7. Article 28 a of the Environmental Code. This will be

investigated further and if it is assessed that there is a risk of significant impact, a

Natura 2000 permit will be sought.

Several inventories, including bird inventories and bat inventories, will be carried

out and the results will be attached to the upcoming application.

The marine environment will also be affected in connection with the construction

of a new cooling water intake and the possible construction of a new discharge

tunnel, for which reason marine inventories will be carried out.

There are known ancient ruins and other cultural and historical artefacts in the

area that may be affected by the establishment. The presence of ancient

monuments and any impact on them will be investigated further as part of the

process of preparing application documents. Vattenfall will seek the permits

39 (62)

required under the Cultural Environment Act in cases where the ruins are at risk

of being affected by the construction. If additional ancient ruins are found during

excavation, this will be handled in accordance with the provisions of the Cultural

Environment Act.

7.2.2. During operation

It will be investigated whether operating the planned operations may have a

significant impact on the environment in the Natura 2000 area Båtafjorden and

how the Biskopshagen Nature Reserve will be affected by the activity, as well as

species worthy of protection in the surrounding area. How intake and discharge of

cooling water, among other things, may affect the marine environment will also be

investigated as part of the application.

After the facility is built, no further impact on the cultural environment is expected.

7.3. Outdoor life, recreation and landscape

7.3.1. During construction

During construction, the landscape will gradually be transformed through

earthworks and civil engineering works. The project will take place in a landscape

that is currently home to large and tall buildings and power lines at the Ringhals

Nuclear Power Plant.

Accessibility to the Värö Peninsula will be limited and possibly cease during the

construction period, which may affect the possibility of outdoor activities in the

area for certain periods.

7.3.2. During operation

The visual impact of the completed facility on the landscape depends on the

supplier and technology choice. Some designs involve the reactors being blasted

into the rock while others involve placement above ground. The maximum height

of the facility may be on par with the Ringhals Nuclear Power Plant’s existing

installations/buildings. A landscape image analysis will be produced as part of the

application.

While the operation is ongoing and under closure, the land within the operation

area will not be able to be used for outdoor activities and recreation. Accessibility

to unoccupied parts of the Värö Peninsula may become more difficult or cease

during the operation of the facility. In the parts of the nature reserve that will need

to be used for the operation, it will not be possible to practice outdoor activities.

40 (62)

7.4. Resource usage

7.4.1. During construction

Resource use during construction will be based on circular principles, which aim

to reduce resource use and utilise resources in a sustainable manner.

During construction of the facility, large amounts of building materials such as

steel, concrete, cement, aggregates/sand/gravel and certain metals such as

copper and aluminium will be used. The use of primary raw materials and

resources will be minimised and, where possible, supplemented with reused or

recycled resources.

During construction, a large number of chemical products will also be used. In

addition to pure building materials, there will be explosives, paints, welding gases

and maintenance chemicals, for example. Routines for storage, handling of

chemicals and disposal of chemical residues will be developed and will be in

effect during the construction and operation phases.

Fuels, mainly in the form of diesel, for work vehicles will be available. The

possibility of using electric transport and more sustainable fuels, with the aim of

minimising greenhouse gas emissions, will be investigated.

Electricity will be consumed for lighting, among other things. Parts of the

electricity requirement may be produced with electricity generators if it is not

possible to ensure electricity supply in another way.

Municipal water will be used for work such as concrete pouring, flushing, cleaning

and the like. Furthermore, municipal water will be used for sanitary purposes in

construction sheds, offices and residences.

7.4.2. During operation

Uranium dioxide is used as fuel in reactor tank(s). Fuel consumption is estimated

to be a maximum of 70 tonnes of uranium dioxide per year for the entire

operation.

Operation and maintenance of the facility will require several different chemical

products, but which products these will be has not yet been studied in detail.

When it comes to operating chemicals, these depend partly on the choice of

reactor technology and supplier. Examples of operating chemicals that may be

relevant are boric acid, hydrazine, hydrogen gas and lithium hydroxide. To

regenerate the filters used to completely desalinate process water, sodium

hydroxide and sulfuric acid are also required. Chlorine or hypochlorite, which may

be added to the cooling water to reduce the growth of marine organisms, are

further examples of possible operating chemicals. The maintenance chemicals

will include various lubricating oils, greases, solvents, cleaning agents and the

like. Vehicle service and fuel management will take place. All handling of

chemical products will comply with applicable legal requirements and all liquid

chemicals will be stored safely using embankments or equivalent. Collection

materials will be available for handling spills. Substitution of chemical products to

41 (62)

chemicals that are less environmentally and health hazardous will be

implemented whenever possible.

Internal and external transport will consume fossil fuels or biofuels. The possibility

of using electric transport or a larger proportion of sustainable fuels, with the aim

of minimising emissions, will be investigated.

The operation of the facility will use electricity to operate pumps, ventilation, some

heating, lighting, instrumentation and the like. Maximum electricity consumption

for operating reactors with an output of 2,800 MWe is estimated at approximately

170 MW in installed power.

Municipal water will be used in the process to cool the core and allow continued

nuclear reaction, as well as to produce steam for turbine operation. This takes

place in a closed process where the water is circulated. An alternative to using

municipal water is to use seawater for the process. Regardless of the origin of the

water, it will need to be desalinated, via ion exchange and osmosis treatment,

before it is used in the process. To reduce consumption, a large portion of the

process water will be purified and reused during the operational phase. Municipal

water will also be used for sanitary purposes.

Seawater will be used to cool the nuclear facility. Cooling water consumption, in

the form of seawater, is estimated to amount to approximately 120 m 3 per

second.

7.5. Waste

7.5.1. During construction

Waste management during construction will be based on circular principles, which

aim to reduce resource use and waste, and promote the reuse and recycling of

materials in a sustainable manner. Excavated materials that arise in the area will

be utilised in the project to the extent possible. Construction waste will be

managed with a focus on recycling and reuse, and in accordance with applicable

regulations to minimise the impact on human health and the environment.

7.5.2. During operation

Waste generated outside the controlled area is conventional waste such as

packaging materials, office supplies, plastic, wood, metal and household waste.

The conventional waste can be both non-hazardous and hazardous waste and

will be handled in accordance with the Waste Regulations (2020:614) and

delivered to transporters and recipients who hold the necessary permits.

The waste that is expected to arise in the operation, after preventive measures,

will be handled and classified based on established routines depending on the

type of material and the amount of radioactivity. Radioactive waste will be

managed with safety as the highest priority and in accordance with laws and

regulations. The waste that will arise during operation is assessed to be of the

same nature as the waste that arises at other nuclear power reactors in Sweden.

42 (62)

7.6. Transportation

7.6.1. During construction

During construction, transportation of, among other things, soil and rock

materials, building materials and construction components to and from the

operational area will be carried out. There are existing roads to and within the

area, however, some roads may need to be strengthened to handle road

transport to and from the area during construction. The main transport route is

road 848 from Väröbacka, via exit 56 to road E6, see Figure 13. In addition,

routes 850 and 847 can also be used. It should be taken into account that route

847 passes through the Natura 2000 area Båtafjorden.

Figure 13. Overview map of possible transportation routes (Lantmäteriet, Vattenfall).

Transporter Transport

Verksamhetsområde Area of activity

Huvudsaklig transportväg Main transport route

Alternativ transportvåg Alternative transport route

The proximity to suitable ports, such as Videbergshamn, the ports of Halland or

the Port of Gothenburg, enables sea transport of bulky equipment and more.

Videbergshamn has a permit for handling raw materials and materials connected

to nuclear facilities. Other ports have permits for handling, among other things,

containers, bulk, RoRo, steel and sheet metal products and liquid bulk.

The foundation and ground preparation phase is estimated to generate

approximately 250–300 truck transports (500–600 vehicle movements) daily for

43 (62)

the transport of excavated materials and rock material. This is provided that all

rock material that is brought up is transported away from the facility. However,

some of the rock material will likely be used for backfilling and ground levelling at

the construction site. During the subsequent construction phase of approximately

eight years, approximately 60,000–120,000 truck transports are estimated to

occur, which corresponds to 120,000–240,000 vehicle movements or

approximately 40–80 vehicle movements per day. To keep the number of

transports down, Vattenfall will, among other things, plan to ensure that the

vehicles do not travel empty on any route and work towards a high fill rate in the

vehicles.

In addition to truck transport, approximately one hundred sea transports are

estimated for the transport of heavy components. Depending on the distribution

between the respective modes of transport, the stated number of transports may

vary. An increased number of sea transports reduces the need for truck transport

and vice versa. Transportation to and from the facility for personnel is not

included in the figures given above.

7.6.2. During operation

During the operational phase, goods transport will mainly take place via truck.

Exceptionally, sea transport will take place. Transport will consist of internal

transport, external freight transport and staff travel to and from work. The number

of vehicle movements per day is estimated to be approximately 2,300, of which

approximately 150 vehicle movements will consist of heavy transport. The main

transportation route will be the same as during the construction phase.

7.7. Noise, light and vibrations

7.7.1. During construction

Noise disturbances will occur in the immediate vicinity during the construction

period. Work at the beginning of the construction phase will, among other things,

give rise to vibrations and a higher noise level, especially during blasting and

handling of explosives. Crushing of materials may also occur. Increased

transportation in the area will generate noise.

A noise investigation will be prepared as a basis for assessing the noise levels

caused by the operation and any need for measures to ensure that the Swedish

Environmental Protection Agency's current guideline values for noise from

construction sites are met. Noise from traffic to and from the construction site will

be assessed based on the guideline values that apply to traffic noise.

Other possible disturbances during the construction period include vibrations and

light, as the construction area will be illuminated in the evening and at night.

7.7.2. During operation

Noise sources in the form of transportation, ventilation systems, testing of safety

valves and similar activities will give rise to some noise in the surrounding area.

The noise investigation to be carried out will assess how the planned operations

44 (62)

relates to the guideline values stated in the Swedish Environmental Protection

Agency's guidance for industrial noise and the possible need for protective

measures.

7.8. Groundwater

7.8.1. During construction

In connection with the construction of the facility and associated infrastructure, it

will likely be necessary to drain groundwater through pumping. Vattenfall will carry

out additional surveys and investigations regarding groundwater and geotechnical

engineering. The results of the investigations will, among other things, report the

area of impact from the groundwater diversion and whether protective measures

will be needed, in the form of, for example, retaining walls or foundation walls to

ensure that ground levels and groundwater levels on surrounding land are not

negatively affected.

Vibrations from blasting work can also activate cracks with the risk of surface

water moving downwards and with the risk of affecting the groundwater level. If

there are remaining wells in the area, a well inventory may be necessary, which

includes level measurement and water quality control in nearby wells to determine

the current situation for future checks.

7.8.2. During operation

As the facility may be lowered into the bedrock, below the groundwater level,

groundwater infiltration cannot be ruled out. The amount of groundwater leaking

in depends on the presence of cracks in the rock and the degree of sealing. The

penetrating water must be removed to avoid compromising the safety of the

facility. This will be done with pumps and the water will be led up to ground level

and then diverted via the storm water system. Regular monitoring of groundwater

levels will be included as part of the future environmental monitoring program.

7.9. Emissions into water

7.9.1. During construction

The seawater in the immediate area will be turbid during blasting, dredging and

construction of a new cooling water intake and a possible new cooling water

outlet. The impact and the need for any measures to minimise the impact on

benthic flora and fauna and the marine environment will be investigated as part of

the application.

7.9.2. During operation

Seawater for cooling will be filtered from fish, clams, jellyfish and seaweed. Water

containing separated cleaning material will be removed using flushing pumps.

The water will contain varying amounts of cleaning agent. During periods of low

sewage levels, this water is returned directly to the sea. In the case of large

45 (62)

amounts of cleaning, the cleaning water will instead be drained. This is done to

avoid large amounts of cleaning agent being returned to the cooling water which

is then reinfiltrated into the plant. After dewatering, the sludge can be used as a

resource, depending on its content. To reduce fouling in the cooling water system,

chlorination of the cooling water tunnels may be carried out through

environmentally adapted dosing of hypochlorite, which is included with the cooling

water. The concentration that comes with the cooling water should be kept as low

as possible. Alternatively, mechanical cleaning of the tunnels will be carried out.

Mechanical cleaning is carried out by adding so-called cleaning balls to the

cooling water.

The cooling water circulating within the plant will, when released back into the

sea, have a temperature of around 10 degrees warmer than when the water was

taken in. In the sea, the heated cooling water will be mixed with the surrounding

seawater, which means that the heat output of the discharge will decrease.

When the plant is in operation, process water also occurs in the form of leakage

water, drainage water, flushing water when replacing ion exchangers and in

connection with cleaning. The process water is purified through filtration and ion

exchange, and most of the water can be reused in the process. However, smaller

amounts of purified process water need to be discharged from the plant via the

cooling water outlet. Small amounts of radioactive effluents will accompany the

purified process water into the sea. These substances can give rise to a limited

concentration of radioactive effluents in water recipients and in sediments and a

limited radiation dose to humans via the ingestion of fish and shellfish. For

nuclear activities, strict requirements apply to limiting radiation doses to the public

and discharge of radioactive effluents into the environment, including through

regulations on so-called dose restrictions and radiological acceptance criteria.

Current and possible future regulations in the area will be taken into account. An

assessment of exposure in the environment, including calculation of dose rates in

biota and radiation dose to humans, will be carried out, see also section 7.13.2.

Small amounts of process and maintenance chemicals such as boric acid, lye and

sulfuric acid may also be carried with the process water/cooling water into the

sea.

Storm water from paved surfaces will be diverted to the recipient at the inlet and

outlet channels. Storm water that is at risk of being contaminated by oil must pass

through oil separators before being discharged. The need for retention dams is

being investigated. A storm water investigation will be carried out as part of the

application.

The discharge of water from the operation will either take place to the Vändelsö

Archipelago water body (SE571720-120640) or to the coastal waters of North

Central Halland (SE570000-120701). Both water bodies have moderate

ecological status and they do not have good chemical status. The impact on

relevant quality factors for the status classification will be reported in the

application.

46 (62)

7.10. Emissions to air

7.10.1. During construction

During construction, work machinery and transport will cause emissions of,

particles, carbon dioxide, nitrogen oxides, sulphur dioxide and particles into the

air during construction. The possibility of using electric transport and more

sustainable fuels, with the aim of minimising emissions, will be investigated.

Smaller amounts of solvents will be released from building materials, degreasing,

paints and more.

Construction-related dust can periodically cause disturbances in the immediate

surroundings. Dust generation is expected primarily during the initial construction

work, for example during blasting and handling of rock masses. Construction-

related dust may have negative effects on the area's flora but is primarily a work

environment issue. To reduce dust, several different protective measures can be

taken if necessary. Examples of measures include watering or salting gravel

roads and areas, watering storage areas, vehicle beds, and connecting water to

nozzles on crushing machines and conveyor belts if these are used.

7.10.2. During operation

The operation of the reactors will result in small amounts of radioactive

substances being discharged into the atmosphere. These substances are diluted

in the air and only cause limited impact on the environment. An assessment of

environmental exposure, including calculation of dose rates in biota and radiation

dose to humans, will be performed. See also section 7.13.2.

Recurrent test operation of backup power units will result in emissions of primarily

carbon dioxide, nitrogen oxides, sulphur dioxide and particulate matter. In

addition, transport to, from and within the operating area generates similar

emissions into air.

7.11. The climate impact of the operation

7.11.1. During construction

The construction of planned operations will require materials such as steel,

concrete and other energy-intensive construction materials and inputs. Transport

and construction equipment will consume diesel and other fuels. To minimise the

impact on the climate during construction, the project will focus on resource

conservation. The use of resources with a lower climate footprint, such as

recycled materials, as well as electric transportation and more sustainable fuels,

will be investigated and implemented where possible.

7.11.2. During operation

Electricity production at a nuclear power plant is fossil-free. From a life cycle

perspective, the climate impact of a nuclear power plant is low and carbon dioxide

47 (62)

emissions amount to approximately 5.71 grams per kWh 18 for existing nuclear

power, which is lower than the corresponding figure for both wind and

hydropower.1516 . The majority of greenhouse gas emissions are linked to

upstream and downstream processes such as the production of nuclear fuel and

materials for the infrastructure required for the distribution of electrical energy.17 .

The operation of the nuclear power plant itself accounts for a smaller portion of

carbon dioxide emissions. Emissions of substances during the operation of the

plant that contribute to the greenhouse effect, eutrophication and acidification in

the form of nitrogen dioxides, carbon dioxide and sulphur dioxide are generated

primarily during transport to and from the plant and during test runs of backup

power plants.

To minimise the impact on the climate during operations, the business will work

actively to conserve resources. Resources with a lower climate footprint, such as

recycled materials, electric transportation and more sustainable fuels, will be used

where possible.

7.12. Vulnerability to climate change and external

environmental events

7.12.1. During construction

The construction work will take place over a shorter period and may be affected

by temporary weather phenomena but will not be affected by climate change in

the longer term.

7.12.2. During operation

Nordic nuclear power is generally considered to be well-equipped against

consequences linked to climate change as nuclear power production is affected

by few weather and climate-related factors compared to the production of other

types of energy. However, weather-related events can affect operations and

delivery reliability and have financial consequences. Examples of such weather-

related events are lightning strikes, which can generate disruptions to the network 18 .

Climate change in the form of increased sea temperature can lead to an

increased occurrence of marine organisms that cause clogging of cooling water

pipes. Increases in sea temperature can also lower heat output and thus lead to

reduced production. Sea level rise is also a factor to consider. Based on the

scenarios that the Intergovernmental Panel on Climate Change (IPCC) assesses

as likely, it is estimated that the average water level in Varberg Local Authority in

2100 could rise by up to one metre compared to today. Estimated extreme sea

level rise with a return period of 100 years is stated at 1.6 metres above mean

sea level. 18 Planned operations will be located at an altitude of approximately

four to six meters above current sea level. Sea level rise is therefore not

considered to result in a need for additional protective measures.

Other external events to be taken into account in the continued work include the

risk of landslides, earthquakes, torrential rain, storms and fires during prolonged

droughts.

7.13. Risk and safety

7.13.1. During construction

To reduce the risk of environmentally related accidents such as emissions to

surrounding land and water environments during the construction phase,

necessary risk assessments will be carried out, protective measures and routines

will be implemented. Equipment for cleaning up chemical and fuel spills will be

readily available.

Vattenfall plans to build several reactors and bring them into operation in stages.

Construction work will then continue on the site while parts of the facility are in

operation. Risks associated with this will be analysed. Risks linked to the nearby

operations at the Ringhals Nuclear Power Plant will also be analysed.

7.13.2. During operation

7.13.2.1. Radiation safety and radiological risks

The operator's radiation safety work is a central part of the assessment under the

Nuclear Activities Act. The Swedish Radiation Safety Authority sets requirements

for radiation safety and monitors that those who operate the facilities comply with

applicable regulations and requirements.

The concept of radiation safety encompasses radiation protection and safety.

Radiation safety has the highest priority in nuclear operations. The purpose of all

safety work is to prevent and mitigate the consequences of an accident, so that

human health and the environment are protected against unwanted effects of

radiation now and in the future. The operation's radiation safety work shall be

maintained at as high a level as is practically possible and it shall be further

developed based on operational experience and taking into account scientific and

technical developments. In accordance with the principle of defence in depth, the

safety of a nuclear facility shall be ensured through several successive protective

mechanisms that are independent of each other. This principle covers both the

functional and structural safety of the facility, see chapter 3.2.3. When designing a

nuclear facility, possible operational disruptions and accidents must also be taken

into account. In addition, all fissile material is recorded and checked in

accordance with the international non-proliferation treaty in order to prevent

unauthorised persons from gaining access to the material.

18 Unger et al. (2021) The Impact of Climate Change on Nuclear Power. REPORT 2021:744. Energy research.

49 (62)

The operations are expected to result in low discharges of radioactive effluents

into the air and water. These discharges are not considered to lead to any

adverse effects, either in the local area or in another country. Radiological

environmental consequences resulting from the planned operations, i.e. radiation

doses to a representative member of the public, activity concentrations in the

environment and dose rates to representative organisms, will be calculated and

assessed.

In the event of an accident, the discharge of radioactive effluents under adverse

weather conditions may affect a large area. However, the application of extensive

preventive and mitigation measures means that no serious consequences are

expected to arise either in the immediate vicinity or in another country.

Radiological consequences in the surrounding area will be assessed and reported

on with a view to the potential for accidents.

7.13.2.2. Risks covered by the Environmental Code

Planned operations also carry a risk of small-scale incidents and accidents. This

could, for example, involve spills of chemicals, breakdowns of purification

equipment, etc. These risks linked to the Environmental Code will be analysed so

that adequate protective measures can be taken.

7.13.2.3. Seveso Act

A preliminary assessment indicates that the planned operations are covered by

the Seveso Act. The Seveso Act governs activities where large quantities of

specified hazardous substances or substances with specified hazardous

properties are present. The law has two levels of requirements. If the quantity

encountered exceeds the lower limit quantity, the operation is covered by the

lower requirement level. If the amount of hazardous substances present exceeds

the higher limit, the operation is subject to the higher level of requirements. It is

currently being investigated whether the applied for activity will constitute a higher

or lower level Seveso activity.

If the planned operations are covered by the higher level of requirements, a safety

report with associated appendices will be prepared and included in the application

in accordance with the Environmental Code. If the planned operations are

covered by the lower level of requirements, an action plan and risk analysis will

be developed and included in the application in accordance with the

Environmental Code.

The present consultation also constitutes a so-called Seveso consultation in

accordance with Chapter 6. Article 29(2) of the Environmental Code and below

describe risks and possible measures to prevent and limit possible serious

chemical accidents. The consultation also concerns factors in the environment

that may affect the safety of the operation in accordance with Article 13 of the

Seveso Act.

Risks and protective measures

During operations, substances with environmentally hazardous properties and

substances that are considered to pose a physical hazard under the Seveso

50 (62)

legislation may be relevant. Examples of chemicals that may be handled in

quantities for which the Seveso Act becomes applicable are hydrazine, hydrogen

gas, sodium hypochlorite, acetylene, diesel and LPG. Based on the properties of

the hazardous substances and experiences from the Ringhals Nuclear Power

Plant19 the following risks may be relevant:

• Hydrazine is a chemical substance used to prevent corrosion in piping

systems. Hydrazine is corrosive, toxic, carcinogenic and very toxic to

aquatic organisms. Leakage of hydrazine can produce toxic fumes. The

extent to which spread can occur depends partly on prevailing weather

conditions and the size of the leak. If hydrazine spills and crystallizes, a

fire may occur upon contact with organic material.

Examples of protective measures that may be taken include necessary

embankments, continuous leakage monitoring, sprinkler systems and

daily patrols.

• Hydrogen is a flammable gas. The biggest consequences linked to the

handling of hydrogen gas are an explosion or a jet flame from an ignited

gas cylinder leading to damage to personnel and the facility.

Examples of protective measures to minimise the risks associated with

hydrogen handling include hydrogen detection and daily patrols.

• Risks associated with handling acetylene and LPG are primarily linked to

fire.

Examples of protective measures include fire alarms and access to fire

extinguishers.

• Leakage of diesel can lead to contamination of soil and water.

Examples of protective measures that may be taken include the

necessary embankment and access to a sump or equivalent for

collection.

• When sodium hypochlorite and hydrochloric acid are mixed, chlorine gas

is formed.

Separated embankments and well-functioning alarm routines are

examples of preventive measures.

In addition to those listed above, various protections are installed for conventional

risks such as fire, leakage, explosions and turbine failures.

For fire protection, the facility will be divided into fire cells. The facility will be

monitored with detectors connected to the central control room, which is staffed

24/7. Local fire services are available at the facility. Duplicate fire pumps will be

installed to supply fire water networks and sprinklers at locations that are

particularly important to protect from a reactor safety perspective.

20.10.2023 and 02.12.2024.

51 (62)

For leaks from transformers with large amounts of oil and for diesel tanks,

collection devices will be available in the form of embankments that will allow any

leakage to be collected.

To prevent the occurrence of explosions, explosive equipment will be placed in

areas with a low risk of ignition. Special procedures for working on these systems

will be in place.

To prevent turbine failures, the systems are built with high quality requirements.

Monitoring is extensive to identify errors early. The layout of the turbines is also

done so that if parts should come loose, this will not negatively affect the safety of

the facility.

Environmental factors

As part of the work of identifying and assessing risks, all Seveso operations must,

in accordance with Article 13 of the Seveso Act, investigate which environmental

factors may affect the safety of the operation. Environmental factors include both

man-made circumstances and natural factors. Special consideration must be

given to other Seveso activities in the vicinity. The nearest Seveso operation is

the adjacent Ringhals Nuclear Power Plant. The risks at the Ringhals Nuclear

Power Plant are assessed to be of the same nature as for planned operations

since the same/similar hazardous substances are used there.

Other Seveso operations in the surrounding area consist of Södra Cell Värö and

the Lahall power plant, located approximately 5 km from the planned location. At

Södra Cell Värö, various hazardous substances are used for the production of

paper pulp. The risk inventory conducted for the operation shows that there is no

risk that an unwanted event within the factory area could have serious

consequences for personal safety or the environment outside the operation area.

Lahall’s power plant is a backup power plant for Svenska kraftnät and Ringhals

Nuclear Power Plant. The facility handles fuel in the form of diesel and the

greatest risk identified is leakage of fuel into the surrounding environment.

Otherwise, there are no Seveso operations or other industrial operations in the

immediate area that are considered to constitute relevant environmental factors.

Accidents linked to the transport of dangerous goods could constitute an

environmental factor. The nearest recommended route for dangerous goods is

route E6/E20 approximately 6 km east of the planned location. The West Coast

Railway extends approximately 4 km east of the planned location.

Natural environmental factors are described in more detail in section 7.12 and

include, for example, floods and lightning strikes. In addition, intentional damage

is also an environmental factor that will be taken into account.

8. Upcoming environmental impact assessment

8.1. Proposal for scoping

Scoping the content of the environmental impact assessment involves a focus on

essential issues and aspects that are to be impact assessed. The scope of an

environmental impact assessment should be adapted to the environmental impact

52 (62)

and other effects that the activity entails. The environmental impact assessment is

therefore planned to focus on the subject areas of the natural environment,

landscape, waste, water intake, impact on groundwater, transport, noise,

discharges into water, and risk and safety. Land use, other area protection, raw

materials and chemical products, emissions to air, vulnerability to climate change

and external events will also be described and assessed. Consequences for

environmental objectives and environmental quality standards are described

throughout. The environmental impacts of the planned operations will be

compared with a zero alternative, which means that the planned operations are

not established on the site.

Geographically, the impact assessment will mainly be limited to the area directly

affected by the planned operations. However, geographical scoping for each

aspect may vary and is highlighted to the extent deemed necessary.

In terms of time, the environmental effects are assessed in the short, medium and

long term.

• The short term consists of the construction phase, which corresponds to

approximately 10 years.

• Medium term is up to between 25 and 30 years.

• Long term corresponds to the facility's lifespan until decommissioning.

8.2. Assessment criteria

The purpose of the environmental impact assessment is to report the

consequences of the planned operations on human health and the environment.

The environmental impact assessment is qualitative, but is mainly based on

certain frameworks that are referred to here as assessment bases. By applying

the assessment criteria, the environmental impact of the planned operations can

be put in relation to the value of each aspect.

In the planned environmental impact assessment, the concepts of impact,

consequence and measure will be used. Impact refers to the change in

environmental and health aspects that the planned operations entails compared

to a zero alternative. Consequence refers to the result of the impact and the

degree of impact. The impact and/or consequence can be both direct and indirect

and relate to the value of the aspect, but can also be related to national, regional

and local environmental objectives, environmental quality standards, as well as

national guideline values, limit values and current practices. To avoid or reduce

negative consequences, various measures ( protective measures ) are proposed

where necessary. The assessment is made by weighing the value of the aspect

and the scope of the planned action. The assessment is made in relation to the

zero alternative.

8.3. Suggested table of contents

Proposals for the design of the upcoming environmental impact assessment are

presented in the table of contents below, Table 4. The description in the table

below should be seen as an example of the description of the scoping that the

environmental impact assessment will contain and not as an absolute design. The

53 (62)

table of contents is based on current provisions in Chapter 6 of the Environmental

Code and the Environmental Assessment Regulations (2017:966), the Nuclear

Activities Act and other provisions that are relevant to the current activity. In

addition to an environmental impact assessment, the application will consist of a

main submission including a report linked to the general rules of consideration, a

technical description, an action plan/safety report and a status report, all with

associated appendices.

9. Continued consultation

9.1. The consultation process

Vattenfall intends to conduct the consultation on the planned operations in several

stages. As a first and initial step, a consultation meeting was held with the County

Administrative Board of Halland County, Varberg Local Authority and the Swedish

Radiation Safety Authority. The purpose of the initial consultation meeting was to

discuss the delimitation between the review procedures under the Environmental

Code and the Nuclear Activities Act, the scope and definitions of the procedures,

the location of the planned operations and the continued consultation process.

Vattenfall now intends to continue the consultation by inviting a larger circle of

authorities, but also organisations, particularly those concerned, and the general

public to the consultation, for which this document forms the basis. The

authorities that are to be invited to the consultation are: County Administrative

Board of Halland County, County Administrative Board of Västra Götaland

County, Environmental Protection Agency, Radiation Safety Authority, Swedish

Marine and Water Authority, Swedish Civil Contingencies Agency, Swedish

Transport Administration, Chemicals Inspectorate, Swedish Power Networks,

Swedish Energy Agency, Geological Survey of Sweden, Swedish Geotechnical

Institute, Swedish Maritime Administration, Swedish Police Authority, State

Administrative Board of the Swedish University of Agricultural Sciences, SLU

(Institute for Aquatic Resources), National Debt Office, Swedish Board of

Housing, Building and Planning, Swedish Armed Forces, local safety committee,

Varberg Local Authority, Kungsbacka Local Authority, Mark Local Authority,

Falkenberg Local Authority, West Rescue Service and Greater Gothenburg

Rescue Service. More authorities may be invited to the consultation.

58 (62)

The consultation will take place both in writing and through several consultation

meetings to be held during the first half of 2025.

Further consultation sessions are then intended to be held as the planning work

progresses, and the planned operations can be described more precisely.

Invitations to each consultation event will be made via advertising and direct

mailing to those particularly affected and to organisations that Vattenfall deems to

be affected or have an interest in the planned operations. Affected organisations

have been selected based on, among other things, experience from previous

permit procedures for nearby or similar operations. Those particularly affected are

currently assessed to consist of property owners, users, residents, business

owners, well owners and other rights holders (for example, holders of rights of

way and easements) within the area marked in Figure 14 below and adjacent to

route 850 up to route E6. This group is considered to be particularly affected by

the activities, including in the form of noise, air emissions, groundwater impact,

transportation, visual impact and more. The group also includes owners of

ongoing projects in the area that may be affected by the planned operations. In

addition, Södra Cell Värö, Lahall power plant and Ringhals AB (Ringhals Nuclear

Power Plant) are considered to be particularly affected based on the requirements

of the Seveso legislation linked to environmental factors. The direct mail will

contain a detailed description of why each recipient is considered to be

particularly affected.

9.3.4. Your rights

You have several rights in relation to Vattenfall's processing of your personal data. Information about your rights and how you can exercise them is described below. Please note that your rights only apply to the extent that they apply under applicable data protection legislation and are therefore limited in some cases.

9.3.5. Right of access

You have the right to know what personal data Vattenfall processes about you. You also have the right to access such personal data through a so-called register extract and request further information about its processing.

9.3.6. Right to rectification

You have the right to request that incorrect or incomplete personal data that Vattenfall processes be corrected or supplemented.

9.3.7. Right to erasure

In certain cases, you have the right to have your personal data that Vattenfall processes deleted. The right to erasure applies if processing the personal data is no longer necessary for the purpose for which it was collected or if the personal data is processed based on your consent and you choose to withdraw your consent. However, Vattenfall will not delete your personal data if your personal data is needed for Vattenfall to fulfil a legal obligation, if it is still necessary to process it for the purpose for which it was collected, or if Vattenfall's interest in continuing to process the data outweighs your interest in having it deleted.

9.3.8. Right to file a complaint

If you have objections or comments about Vattenfall's processing of your personal data, you have the right to contact or file a complaint with the Swedish Data Protection Authority.

9.3.9. The right to object

61 (62)

9.3.10. Right of restriction

You have the opportunity to demand restriction of the processing of your personal data provided that (i) you have objected to the processing and are awaiting Vattenfall's assessment of whether Vattenfall's legitimate interest outweighs it, (ii) you do not believe that the information that Vattenfall has about you is accurate, (iii) the processing is unlawful but you object to the deletion of the personal data or (iv) Vattenfall no longer needs the personal data for the purposes for which it was collected and you need it to, for example, assert legal claims. By requesting a restriction on processing, you have the opportunity, at least for a certain period of time, to stop Vattenfall using the personal data for purposes other than, for example, defending Vattenfall's legal claims.

9.3.11. Miscellaneous

Further information about Vattenfall's processing of your personal data, including further information about your rights, can be found in Vattenfall’s privacy policy https://group.vattenfall.com/se/site-assets/personuppgifter-hos-vattenfall.

Rootsi uue tuumaelektrijaama rajamise ja opereerimise

piiriülene keskkonnamõju hindamine

Rootsi on piiriülese keskkonnamõju hindamise konventsiooni (Espoo konventsiooni) alusel teavitanud

Eestit seoses uue tuumaelektrijaama rajamise projektiga.

Arendaja Vattenfall AB on esitanud loataotluse kahe suure tuumareaktoriga või kolme kuni viie väikese

moodultuumareaktoriga uue tuumaelektrijaama arendamiseks ja käitamiseks, mille kombineeritud

elektrivõimsus on kuni 2800 MWe (vastab soojusvõimsusele kuni 8400 MW). Loataotlus hõlmab ainult

rajatise kavandamist ja käitamist, mitte tuumareaktorite edaspidist dekomisjoneerimist. Lisainfo

kavandatava tegevuse kohta on Rootsi saadetud konsultatsiooni dokumentides, mis on aluseks

keskkonnamõju hindamisel (kirjale lisatud dokument: Basis for the scoping consultation).

Lisaks on Vattenfall koostanud aruande (kirjale lisatud dokument: Background to the Consultation on

Transboundary Impacts), mis annab aluse hindamiseks, milliseid riike kavandatav tegevus võib mõjutada

ja keda tuleks teavitada. Hinnang põhineb reaktori avarii hüpoteetilisel õnnetusel ning hüpoteetiliselt

halvima stsenaariumi alusel tehtud arvutuste tulemused näitavad, et kiirgusdoosid on kõrged lähipiirkonnas,

kuid vähenevad kiiresti kauguse suurenedes. Tegevuse asukohast kaugemal kui 250 km on eluaegsed

doosid alla 1 mSv, mis on ligikaudu võrdne Rootsi elanikkonna tavalise aastase taustkiirguse doosiga.

Naaberriikides saaksid reaktori avarii tagajärjel eluaegsed doosid, mis ületavad loodusliku taustkiirguse

aastadoosi, ainult Taanis ja Lõuna-Norra rannikualadel elavad inimesed.

Lähtuvalt Rootsi määratud vastamistähtajast ootame 7. aprilliks 2025 põhjendatud arvamusi selle kohta,

kas Eesti peaks osalema Rootsi uue tuumaelektrijaama piiriüleses keskkonnamõju hindamise menetluses

(e-posti aadressil [email protected]). Juhul, kui peate vajalikuks Eesti osalemist menetluses, on

oodatud ka põhjendatud arvamused selle kohta, milline oluline kahjulik piiriülene keskkonnamõju võib

Eestile kaasneda, et sellega saaks arvestada keskkonnamõju hindamise materjalide koostamisel.

Lugupidamisega
