Too bad about the delay, but we need like minimum 5 more of these yet, to increase our domestic base load self-reliance and to have replacements our old reactors sa they go off line and also to supply the continent who seems to see the nordic countries as a battery that will bail the germans out of their hole. This has resulted in higher electricity prices in Sweden but also in Finland, I've heard the price of electricity has become to high in places in Sweden that people are turning off their heat pumps and refilling their oil fuel tanks and going back to burning oil while others are firing up their wood boilers again.

21 December 2021
Finland's fifth nuclear reactor, Olkiluoto 3 (OL3), has reached first criticality. The EPR (European Pressurised Water Reactor) is the first new nuclear unit to be commissioned in Finland in over 40 years, and will eventually produce some 14% of the country's electricity.
"First criticality of the OL3 EPR plant unit was reached on Tuesday, December 21, 2021 at 3.22 a.m.", utility Teollisuuden Voima Oyj (TVO) announced. Electricity production will begin when the unit is connected to the national grid, which is expected to happen at the end of January 2022.
"This moment will forever be remembered as a demonstration of persistent work for the commissioning of our new plant unit. It reflects strong nuclear professionalism and a will to make Finland's greatest act for the climate a reality," TVO Senior Vice President for Electricity Production Marjo Mustonen said.
Bernard Fontana, CEO of Framatome, thanked the project teams from Framatome and Areva for their perseverance. "This milestone paves the way for safe, reliable, low-carbon electricity generation to the residents of Finland," he said, adding that the company will continue to support the unit with services ranging from fuel fabrication to long-term operational and outage support.
"I would like to congratulate TVO and all its partners on the completion of Olkiluoto 3," World Nuclear Association Director General Sama Bilbao y Léon said. "This reactor will serve the people of Finland for many decades, providing abundant, round-the-clock clean, reliable and affordable electricity - the importance of which we are painfully reminded of right now."
Finland's parliament in 2002 approved building the country's fifth nuclear power reactor. The vote was seen as highly significant, in that it was the first such decision to build a new nuclear unit in Western Europe for more than a decade. TVO's Olkiluoto site - already home to two operating boiling water reactors - was subsequently selected to host the new reactor.
Framatome ANP's 1600 MWe EPR was selected as the preferred reactor based on operating cost, with Siemens selected to provide the turbines and generators. TVO signed a fixed-price EUR3.2 billion turnkey contract with Areva NP and Siemens for the unit in December 2003, and construction began in 2005. Commercial operation was originally scheduled for 2009, but the project has encountered various delays and setbacks.
The Finnish Government granted an operating licence for OL3 in March 2019. Finland's nuclear regulator, STUK, granted a fuel loading permit in March of this year. Fuel loading was completed on 1 April, at which point an October start-up was envisaged. However, this was postponed to allow for extra turbine overhaul and inspection works by the plant supplier.
Now the unit has started up, its power level will be gradually increased and commissioning tests will be carried out at every power level. Electricity production will start when a 30% power level is reached, TVO said. This is expected at the end of January, with regular electricity production expected to start in June. OL3 is then expected to produce around 14% of Finland's electricity.
The first EPR units came online at Taishan in China, where unit 1 became the first EPR to enter commercial operation in 2018 followed by Taishan 2 in September 2019. In Europe, EPRs are currently under construction in France and the UK: Flamanville 3, currently expected to start up in 2023 with commercial operation in 2024; and two units at Hinkley Point C, currently slated for commercial operation in 2026 (unit 1) and 2027 (unit 2).

Looks like Nuclear is still the most climate friendly solution overall.
