Environmental impact assessment programme for the Olkiluoto nuclear power plants Olkiluoto 1 and Olkiluoto 2
On 5.1.2024, Teollisuuden Voima Oyj submitted to the Ministry of Economic Affairs and Employment an environmental impact assessment programme (EIA programme) in accordance with the Act on the Environmental Impact Assessment Procedure (252/2017). The EIA programme is a plan prepared by the project owner concerning the necessary studies and organisation of the assessment procedure. The assessment programme includes information on the project, its alternatives and a description of the current state of the environment.
Link to the press release on 5th January 2024.
The EIA programme concerns the possibility of extending the service life of Olkiluoto 1 and Olkiluoto 2 nuclear power plant units until 2048 or, alternatively, until 2058. The original planned service life of the Olkiluoto 1 and Olkiluoto 2 plant units was 40 years, until 2018. Their service life was extended earlier to 60 years, which will be met in 2038.Extending the service life with an uprated thermal power is also being analysed. In the thermal power uprating, the starting point is to increase of the reactor`s thermal power by 10 % to 2,750 MW, which corresponds to increasing the plant unit`s nominal electrical power output from the current 890 MW to 970 MW.
The Ministry of Economic Affairs and Employment acts as the competent authority for the environmental impact assessment procedure (EIA procedure). The project will also be subject to a transboundary environmental impact assessment procedure in accordance with the Espoo Convention.
The Ministry will organise a public consultation on the EIA programme 23.1.2024-25.3.2024. The consultation also includes a public event in Eurajoki. The statements and opinions presented will be published on the Ministry´s website and will be taken into account in the competent authority's statement on the EIA programme.
The public event was held on 6 February 2024 at the Olkiluoto Visitor Centre in Eurajoki. The Finnish-language recording of the event can be viewed through this link.
