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.

Teollisuuden Voima Oyj (TVO), owner and operator of Finland’s Olkiluoto nuclear power plant, has announced a further delay to the start of regular electricity generation at Unit 3. Commercial operation is now projected to begin this December, rather than the previously announced September. A report from Reuters puts the date at December 10.

According to TVO, material that had detached from the steam guide plates was found in the turbine’s steam reheater last month, requiring inspection and repair work.

The Finnish public’s support for nuclear power is at an all-time high, according to a recent opinion poll conducted by Kantar Public, a London-based consulting and research firm.

Commissioned by Finnish Energy—the trade association for Finland’s energy sector—the poll finds that 60 percent of respondents have either a “fully positive” or “mainly positive” perception of nuclear power as an energy source (34 percent and 26 percent, respectively), up from 49 percent in a 2021 Kantar poll.

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.)

Posiva Oy, the company responsible for the disposal of Finland’s spent nuclear fuel, announced last week that it has begun excavating the first disposal tunnels at the Onkalo deep geologic repository near the Olkiluoto nuclear power plant.

Finland’s Onkalo repository a “game changer,” says IAEA’s Grossi

Onkalo, Finland’s deep geologic repository for spent nuclear fuel, has been characterized as a game changer for the long-term sustainability of nuclear energy by Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

“Finland has had the determination to move forward with the project and to bring it to fruition,” Grossi said during a November 26 visit to Olkiluoto, Finland, where the repository is under construction. “Waste management has always been at the center of many debates about nuclear energy and the sustainability of nuclear activity around the world. Everybody knew of the idea of a geological repository for high-level radioactive nuclear waste, but Finland did it.”

Posiva Oy, the Finnish company tasked with researching and creating a method for the permanent disposal of spent fuel from Finland’s Olkiluoto and Loviisa nuclear power plants, obtained a license to construct the Onkalo repository in 2015, marking the first time that a construction license for a geological disposal facility was issued anywhere in the world. The site near the Olkiluoto plant was chosen following several years of screening a number of potential sites.
