The Olkiluoto Nuclear Power Plant (Finnish: Olkiluodon ydinvoimalaitos, Swedish: Olkiluoto kärnkraftverk) is one of Finland's two nuclear power plants, the other being the two-unit Loviisa Nuclear Power Plant. The plant is owned and operated by Teollisuuden Voima (TVO), and is located on Olkiluoto Island, on the shore of the Gulf of Bothnia, in the municipality of Eurajoki in western Finland, about 20 kilometres (12 mi) from the town of Rauma and about 50 kilometres (31 mi) from the city of Pori.
The Olkiluoto plant consists of two boiling water reactors (BWRs), each with a capacity of 890 MW, and one EPR type reactor (unit 3) with a capacity of 1,600 MW.[1] This makes unit 3 currently the most powerful nuclear power plant unit in Europe and the third most powerful globally.[2][3] Construction of unit 3 began in 2005. Commercial operation, originally scheduled for May 2009,[4][5] began on 1 May 2023.[6]
A decision-in-principle for a fourth reactor to be built at the site was granted by the Finnish parliament in July 2010,[7][8][9] but in June 2015 TVO decided that it would not apply for a construction license for Olkiluoto 4.[10]
