The Unit 3 EPR at Finland’s Olkiluoto nuclear power plant has reached its full capacity of approximately 1,600 MWe for the first time, plant owner and operator Teollisuuden Voima Oyj has announced. Olkiluoto-3 is now the most powerful reactor in Europe and the third most powerful globally, according to TVO. (Currently, the world champions in that department are China’s 1,660-MWe Taishan-1 and -2, also EPRs.)

Unit 1 at the Taishan nuclear power plant in China has been shut down to examine fuel rod damage and conduct maintenance, China General Nuclear Power Group (CGN) reported last Friday.

If Taishan-1 were operating in France, Électricité de France would shut down the reactor in order to assess the situation in progress and stop its development, according to a July 22 press release from EDF. The 1,660-MWe French-designed EPR—the recent subject of sensational press coverage of fuel rod failures—operates in China’s Guangdong Province.

The facts, once known, were uncomplicated. At Taishan-1 in China—the first Framatome EPR to be commissioned—operators detected an increase of fission product gases within the primary coolant circuit sometime after the reactor’s first refueling outage in October 2020. The cladding on a handful of the more than 60,000 fuel rods in the reactor had been breached, posing an operational issue—but not a public safety issue—for the plant.
