Denmark’s Seaborg Technologies and Norsk Kjernekraft (aka Norwegian Nuclear Power) have signed a letter of intent to investigate the possibility of deploying Seaborg’s 100-MWe compact molten salt reactor (CMSR) in Norway.

Consulting company TVO Nuclear Services (TVONS), a subsidiary of Teollisuuden Voima Oyj, owner and operator of Finland’s three-unit Olkiluoto nuclear plant, has signed a memorandum of understanding with Norsk Kjernekraft, aka Norwegian Nuclear, a firm established last July with the goal of bringing small modular reactors to power reactor–deprived Norway.

A June 27 announcement from TVO said the new MOU provides the Norwegian firm with “access to the know-how and experience of one of the world’s best-known nuclear power companies” and stressed TVO’s 60 percent ownership of Posiva, the company responsible for the disposal of Finland’s spent nuclear fuel. “Posiva has successfully built the world’s first final disposal facility for high-level nuclear waste,” TVO stated. “This is decisively important for Norwegian Nuclear’s plans for the management of the entire life cycle of nuclear power.”

Germany completes nuclear phaseout; better news from Finland

Ignoring a last-minute plea from a long list of scientific luminaries (including Nobel laureate Steven Chu and climate scientist James Hansen) to reconsider, as well as recent polls showing pronuclear sentiment among a majority of its population, Germany shut down its last three operating nuclear power plants late Saturday, ending 60-plus years of electricity generation from fission. (Germany’s first nuclear power plant, Kahl, was commissioned in 1961 and closed in 1985.)

New Finnish reactor at full power

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.)

Olkiluoto-3 test production phase resumes after repair work

Teollisuuden Voima Oyj (TVO), owner and operator of the Olkiluoto nuclear power plant in Finland, has resumed Olkiluoto-3’s test production phase, following completion of maintenance and repair work at the new reactor’s turbine island, the company announced this week.

TVO had announced in June a delay to the unit’s commercial start of some three months—from September to December—after material that had detached from the steam guide plates was found in the turbine’s steam reheater in May, necessitating repair work and a halt to testing.

Europe’s first EPR, Unit 3 at Finland’s Olkiluoto nuclear power plant, was connected to the nation’s grid on March 12, Teollisuuden Voima Oyj (TVO), the facility’s owner and operator, has announced.

Olkiluoto-3 is also the first new Finnish reactor in four decades, and one of only three new reactors in Europe in the past 15 years. (Romania’s Cernavoda-2 began supplying electricity to the grid in August 2007, and Belarus’s Belarusian-1 in November 2020.)

The long-delayed Unit 3 at Finland’s Olkiluoto nuclear power plant has achieved initial criticality, plant owner and operator Teollisuuden Voima Oyj (TVO) announced this morning. The reactor, a 1600-MWe Generation III+ EPR supplied by Framatome, started up at 3:22 a.m. local time.
