Nuclear facilities include nuclear power plants and facilities for nuclear waste management

Olkiluoto 5

Finland has two nuclear power plants with a total of four nuclear reactors. The combined gross output of the reactors is 2,860 MW. In total, the power plants produce more than 20 TWh of electricity.

Fortum Power and Heat Oy operates two pressurised water reactors located in Loviisa. Each reactor has a gross output of 520 MW. The units were commissioned for commercial use in 1977 and 1981. Their operating licences are valid until 2027 and 2030.

Teollisuuden Voima Oyj (TVO) has a nuclear power plant with boiling water reactors in Olkiluoto, in Eurajoki. The power plant consists of two units, each with a gross output of 910 MW. The units were commissioned in 1979 and 1982, and their current operating licences expire in 2018.

TVO is constructing a third nuclear power plant unit in Olkiluoto, with a capacity of 1,600 MW. It is expected to be operational in 2018. The unit is a pressurised water reactor.

On 6 May 2010 and 18 September 2014, the Government made decisions-in-principle on Fennovoima Oy’s nuclear power plant project. On 30 June 2015, Fennovoima submitted to the Government an application for a construction licence. The Government is estimated to consider the construction licence decision in 2018. The new power plant is to be located in Pyhäjoki. The unit will be a pressurised water reactor with an electric power output of 1,200 MW.

VTT Technical Research Centre of Finland is preparing the decommissioning of its research reactor (FiR 1) in Otaniemi, Espoo. The reactor was shut down in 2015.

All nuclear fuel used in Finland is imported.

Low- and intermediate-level operational waste will be disposed of at the plant sites. Finland has final disposal facilities for operational waste in Olkiluoto and Loviisa.

Spent nuclear fuel from the NPPs in operation in Finland will be disposed of in Finland. An encapsulation and disposal facility will be constructed in Olkiluoto at Eurajoki.
