What is siting

What is siting

  • Siting is the process of selecting a suitable site for a facility, including appropriate assessment and definition of the related design bases. (IAEA Safety Guide NS-R-3, 2003)

  • Existing sites

    • site characterization is updated for new units

    • site related design requirements are determined according to current regulatory requirements

  • New sites

    • an extensive siting process

  • Environmental Impact Assessment (EIA) is part of the siting process

    • role of EIA depends on national legislation


Relevant legislation and conventions

Relevant legislation and conventions

  • NPP siting is covered by several fields of legislation, e.g.

    • nuclear

    • environmental

    • land use and building

  • International regulations and treaties are implemented in national legislation

    • IAEA regulations and IAEA sponsored conventions

    • Espoo convention 1991

      • Convention on Environmental Impact Assessment in a Transboundary Context (UNECE, United Nations Economic Commission for Europe)

      • International hearing processes may be quite extensive

    • Aarhus Convention 1998 (UNECE)

      • Convention on Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters

    • marine protection conventions (OSPAR, HELCOM)

  • EU directives in the European Union

    • EIA Directive (85/337/EEC, 97/11/EC )

    • environmental directives (biodiversity, birdlife)

      • Natura 2000 network of natural reserves

      • sometimes extensive clarifications are required


Environmental impact assessment wider view

Environmental Impact Assessment (wider view)

  • EIA is done for all large industrial and infrastructure projects

  • In the European Union the general requirements are set forth in the Council Directive

  • The Directive is implemented in national legislation

    • EIA Act and EIA Decree

  • Goals of EIA

    • promote assessment of environmental impacts and their uniform consideration in planning and decision making

    • improve citizens’ access to information and possibilities to participate

  • EIA report is used as background information in, e.g.,

    • decision making according to the Nuclear Energy Act

    • land use planning

Environmental impact assessment objective and content

Nuclear power plants in Finland

  • Olkiluoto NPP (TVO)

  • 2 operating units - ABB BWRs

  • New EPR under construction

  • EIA completed for a new unit

  • Loviisa NPP (Fortum)

  • 2 operating units - VVERs

  • EIA completed for a new unit

  • Fennovoima Ltd

  • EIA completed for a plant with 1 or 2 units on three sites


Environmental impact assessment objective and content

Licensing is divided in two stages: political decision and safety demonstration

  • Political decisionon a new nuclear power plant is needed as a precondition before major investments are permitted.

  • Political decision is called Decision in Principle (DiP). It concludes whether

  • “a new NPP is in line with the overall good of society”.

    • Environmental Impact Assessment (EIA) has to be completed first for each alternative site

    • EIA report has to be annexed to the application for the DiP.

    • Plant vendor and design are not chosen before the DiP, but main safety features of several alternatives are evaluated during the DiP process.

Environmental impact assessment objective and content

Three licensing steps

  • Decision in Principle (DiP): main emphasis in energy policy

    • process involves both public hearings and Parliament hearings

    • Environmental Impact Assessment and siting have important role

    • DiPopens the way for implementation: licensee can start tendering process.

  • Construction License (CL): main emphasis in nuclear safety

    • main design features are assessed and fixed at this stage

    • At receiving application for Olkiluoto 3 CL, Government committed to issue

    • license as soon as STUK (regulatory body) had found readiness for safe

    • implementation.

  • Operating License (OL): main emphasis in nuclear safety

    • OL is granted after STUK has verified that the plant has been built according to the approved plans, its safety has been demonstrated with adequate analysis, and the operating organization is prepared to operate it safely.


Environmental impact assessment objective and content

Decision in Principle (DiP) - General criteria of approval

  • a new NPP is in line with the overall good of society

    • this is to be decided by the Government and confirmed by the Parliament

  • no safety issues can be foreseen that would prevent the proposed plant(s) from meeting Finnish nuclear safety regulations

    • this is assessed by STUK, full veto right

  • proposed host municipality agrees to provide the site

    • also municipality has full veto right


Environmental impact assessment objective and content

Plant designs studied in DiP phase (OL 3)


Siting role of environmental impact assessment

Siting - Role of Environmental Impact Assessment

  • For the application of Decision in Principle, Environmental Impact Assessment Report is needed as an application document - STUK gives its statement on the Environmental Impact Assessment Report

  • Suitability of site of the NPP is one of the factors in the Decision in Principle phase; location must be appropriate with respect to safety of planned operations and environmental protection must be taken into account.

  • Site must have been reserved for the constructing of NPP in a town plan or a building plan in accordance of with Land Use and Building Act and the applicant must own the land.

  • Effects of local conditions on safety and on physical protection and emergency preparedness arrangements shall be taken into account. Threats posed by the facility to its environment remain extremely minor and heat removal to the environment is reliable.


Environmental impact assessment eia

Environmental Impact Assessment (EIA)

  • EIA is based on environmental legislation that was issued later than the Nuclear Energy Act

    • EIA fits well with the nuclear legislation: it provides useful input for the Decision in Principle which is the first step of NPP licensing according to the Nuclear Energy Act

  • EIA does not require specific information on the plant design

  • EIA was done separately for two alternative (existing) sites: Loviisa and Olkiluoto (for the fifth unit)

The scope of eia

The scope of EIA

  • Environment is defined in a broad sense

    • natural environment, built environment and social environment

  • Radiological issues are considered on a general level

    • more detailed treatment in the licensing process according to the Nuclear Energy Act

  • Non-radiological impacts are emphasized

    • impacts on the natural environment

      • eutrophication due to warm outlet water

    • societal impacts, especially local

      • impacts on land use

      • property values

      • traffic

      • local economy and employment, agriculture and fishing

      • social structure


Radiological issues in eia

Radiological issues in EIA

  • The scope of radiological is to be considered in EIA is not exactly defined in legislation

  • Radioactive releases during normal operation is described:

    • Noble gases 0.65 TBq from OL1-OL2 in 2006 and estimated release per reactor from OL3/OL4 is 0.1 - 10 TBq

    • Iodines (I-131 eq) 0.00016 TBq from OL1-OL2 in 2006 and estimated release per reactor from OL3/OL4 is 0.000001 - 0.001 TBq

    • Aerosols, Tritium and Carbon 14 also given in EIA report

  • Health effects of the population because of radiation are handled in the EIA report

  • Based on discussions with STUK, a release corresponding to the severe accident limit 100 TBq Cs 137 was analysed and described in the EIA report


Non radiological impact issues

Non radiological impact issues

  • Land use

  • Cooling water

  • Water quality and biology

  • Fresh and waste water

  • Monitoring programme

  • Transport and local infrastructure

  • Soil and groundwater

  • Energy economy


Land use

Land use

  • The Land Use and Building Act and Decree prescribe planning pertaining to land use and construction. Regional plans and local master plans are, by nature, far-reaching, general land use plans. Detailed plans are drawn up for the detailed arrangement, construction and development of land use at local level.

  • Nuclear Energy Act decrees that before a detailed plan is drawn up for the area intended for the site of a nuclear facility, and prior to the approval of such a plan where a site is reserved for the construction of a nuclear facility, a statement must be obtained from the Radiation and Nuclear Safety Authority.

  • The environmental permit procedure prescribed in the Environmental Permit Procedures Act applies to the construction and operation of nuclear power plants.


Emergency zones protective zone

Emergency zones: protective zone

  • The plant site is surrounded by a protective zone extending to about a five kilometres' distance from the facility.

  • Land use restrictions are in force within the zone.

    • Dense settlement and hospitals or facilities inhabited or visited by a considerable number of people are not allowed within the zone.

    • The zone may not contain such significant productive activities as could be affected by an accident at the nuclear power plant.

    • The number of permanent inhabitants should not be in excess of 200. The number of persons taking part in recreational activities may be higher, provided that an appropriate rescue plan can be drawn up for the area.


Emergency zones emergency planning zone

Emergency zones: emergency planning zone

  • In accordance with the Ministry of the Interior Order, the nuclear facility is to be surrounded by an emergency planning zone extending to about 20 kilometres from the facility;

  • The zone shall be covered by detailed rescue plans for public protection drawn up by the authorities. The authorities also bear responsibility for the implementation of the plans. In implementation, special attention shall be paid to the characteristics of the site's surroundings, such as archipelagos that are difficult to cross and recreational settlements, for example.

  • The emergency planning zone may not contain such populations or population centres as would render impossible the efficient implementation of rescue measures applicable to them.


Cooling and fresh water waste water

Cooling and fresh water, waste water

  • Large volumes of seawater are needed for the cooling of turbines. No obstacles are foreseen in the intake or outlet arrangements. The effects of elevated outlet seawater temperature on the sea have been studied in EIA Report.

    • about 60 m3/sec in addition to 120 m3/sec for OL1-OL3

    • temperature increase is about 11-12 oC (to average 16 oC, max 25 oC).

  • The processes of NPP need a lot of purified fresh water. Fresh raw water arrangements are appropriate at the site. Raw water is pumped from the 8 km distance from the river via pipeline. Company has plans for water and they will be reviewed in the construction license phase. Tap and process water need for operation is:

    • current daily intake is 300 m3 for OL1-OL2 (2 x 800 MW)

    • estimated daily intake for OL3 is 200 m3 (1600 MW)

    • estimate for the new reactor (OL4) is 200 - 400 m3

  • Effects of waste water are minor

    • estimated daily outlet may be about 700 m3


Cooling water

Cooling water

  • Effects of cooling water into the environment has been studied experientally through modelling and by using three dimensional dispersal calculations. The modelling has taken into account different intake and outlet possibilities. Detailed results have been presented in the EIA Report. In the summer time, results depend on the selected cooling water arrangements and wind direction:

  • temperature increase more than 5 oC in surface waters - estimated area is 1.4 - 3.6 km2

  • temperature increase 3 - 5 oC in surface waters - estimated area is about 5 - 10 km2

  • temperature increase 1 oC in surface waters - estimated area is about 25 km2

  • Summer average 500 m and 1000 m from the discharge point is 27 and and 24 oC respectively and the maximum values are 35 oC and 31-32 oC respectively

  • In the winter time ice conditions have been estimated ( e.g. unfrozen area)


Impact on water quality and biology

Impact on water quality and biology

  • Biological functions are speeded up. Some species may be increased compared to others because of better living conditions. E.g. there is slight increase in algal growth. Eutrophication may have some negative effects on shore areas.

  • The vegetation period will become extended and the increased temperature generally improve the living conditions for plants. The visible changes are limited into areas where temperature is larger than 1 oC above the environment.

  • For fishing, main impact is during winter time because of extended unfrozen area and weak ice. In summer time, valuable fish that like colder waters such as salmon and whitewish stay outside the nearby waters. Generally, effects for fishing are minor. They are expected to remain similar to the present.


Waste water

Waste water

  • OL1-OL2 generate about 70 m3 waste process water on daily basis, OL3 will produce about 200 m3 and the new NPP from 70 to 400 m3 on daily basis.

  • Amount of laundy waste water is currently 3 m3 per day and from the construction sites OL3 and OL4 it is 1,5 m3 per unit per day. When all four units are in operation amount of purified sanitary waste water is expected to be about 180 m3 on daily basis.

  • Waste water is routed via outlet cooling water channels to be distributed into large area

  • The waste water causes minor nitrogen and phosphorous load and oxygen-consuming load in the sea.

  • Their effect is expected to remain so small that the impact probably cannot be distinguished from other nutrient and solid matter loads in the area.


Monitoring programme

Monitoring programme

  • The impact of the environmental loads on the water system will be monitored in accordance with a programme approved by the permit authority. Topics include:

    • temperature measurements

    • physical and chemical monitoring of water

    • biological state of water

    • fish populations and fishing conditions

    • in the winter people are warned about weakened ice

    • operation of waste water treatment plant is supervised by monitoring the treatment efficiency

  • There is also radiological environmental monitoring programme as a license condition of operating license


Effects on transportation and roads local infrastructure

Effects on transportation and roads, local infrastructure

  • Traffic routes,

    • more trafic - more noise, however, effect is very small

    • benefits are more important: better roads in the area

    • Water transport routes prepared for large component deliveries

    • Airline routes / may mean some restrictions for private and military airplanes

  • Grid connections: extra high voltage transmission lines are needed. They require a separe EIA procedure in Finland. This has an effect on land use in the nearby areas.

  • Local infrastructure is developing, services are needed: employment is increased.

  • Tax income is increased in the area because of increased number of taxpayers and presence of large industrial company.

  • Landscape: one extra building in the existing site. In the new site, some natural preservation or other nature values may be in conflict with the industrial development.


Impact on soil and groundwater

Impact on soil and groundwater

  • In Finland, we have old bedrock - good base for industrial facility

    • Foundations need to be prepared: waterproof concrete

    • Final disposal facilities for nuclear waste causes underground excavations

    • Discharges of waste water polluting the soil has been prevented by suitable structures

    • NPP is situated outside the important groundwater areas

Experiences on eia

Experiences on EIA

  • The objective of EIA is to produce information

    • to serve as a basis for decision-making and

    • to increase the opportunities for citizens to receive information, become involved in the planning of the projects and express their opinion.

  • The EIA process is an important forum of communication between the licence applicant ant the local population and officials

  • An opportunity to build local confidence and acceptance of the project

    • local acceptance is important as the acceptance by the council of the site municipality is an absolute condition for a positive Government decision in principle

  • Licence applicants have invested considerable resources in EIA

  • Examples of issues in the final statements by the contact authority

    • effects of warmed cooling water

      • eutrofication

    • influences on Natura 2000 natural reserves


International eia hearing

International EIA hearing

  • Convention on Environmental Impact Assessment in a Transboundary Context (Espoo, 1991) - the 'Espoo Convention‘

    • drafted by the United Nations Economic Commission for Europe (UNECE).

    • in force since 1997

    • All parties to the Convention are entitled to participate in EIAs conducted in other countries if the projects listed in the Convention are likely to cause significant adverse environmental impacts in their territories.
