The Radiation and Nuclear Safety Authority in Finland (STUK) has granted Teollisuuden Voima Oyj (TVO) the permission for making the 1,650 MW Olkiluoto 3 (OL3) EPR nuclear reactor critical and conducting low power tests. The nuclear reaction in the OL3 EPR plant unit’s reactor will be initiated for the first time during December 2021. Power generation is expected to start at the end of January 2022 and regular electricity production in June 2022.
The OL-3 European Pressurized Reactor (EPR) project was built by a consortium of Areva GmbH, Areva NP (now Orano) and Siemens under a fixed-price turnkey contract in Eurajoki (western Finland). Construction started in 2005 for an expected commissioning in 2009. However, the project has been hit by repeated delays, rising costs, and court disputes, and it should be commissioned over 12 years behind schedule. Upon completion, it will be operated by TVO.
