Finland - World Nuclear Performance Report

Finland has two nuclear power plants: Loviisa, a two-unit VVER-440 plant, located 80 km east of Helsinki; and Olkiluoto, about 220 km northwest of the capital, with twin BWR units and an EPR.

In February 2023 the Finnish government approved Fortum’s operating lifetime extension request for an additional 20-year term, which would extend the operation of Loviisa 1&2 until the end of 2050. The units started up in 1977 and 1980, respectively. In May 2024 Fortum awarded a contract to Doosan Škoda Power to modernize the low-pressure turbines at Loviisa as part of its modernization programme.

Teollisuuden Voima Oyj (TVO) is making preparations to extend the operational lifetimes and uprate units 1&2 at its Olkiluoto plant. In January 2024 it submitted an environmental impact assessment to the Ministry of Economic Affairs and Employment.
