Finland’s much-delayed and costly new nuclear reactor, Europe's most powerful by production capacity, has completed a test phase lasting over a year and started regular output, boosting the Nordic country’s electricity self-sufficiency significantly.
The Olkiluoto 3 reactor, which has 1,600-megawatt capacity, was connected into the Finnish national power grid in March 2022 and kicked off regular production on Sunday. Operator Teollisuuden Voima, or TVO, tweeted that “Olkiluoto 3 is now ready” after a delay of 14 years from the original plan.
