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.

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.)

IAEA releases nuclear power status data for 2020

The International Atomic Energy Agency last week released its annual nuclear power status data, collected by the Power Reactor Information System (PRIS), the agency’s publicly available nuclear power database.

According to the IAEA’s data summary, nuclear power in 2020 played an important role as an adaptable and reliable supplier of electricity during the pandemic.

Russian unit begins commercial operation

Unit II-2 at the Leningrad nuclear power plant entered commercial operation on March 22, bringing the total number of operating power reactors in the Russian fleet to 38, state-owned nuclear power corporation Rosatom has announced.

The 1,066-MWe unit is one of two Russian-designed Generation III+ VVER-1200 pressurized water reactors now in service at the plant, the other, Unit II-1, having begun commercial operation in October 2018. There are also two VVER-1200 units up and running at Russia’s Novovoronezh facility, and two additional VVER-1200s are scheduled for Leningrad later this decade. Further, VVER-1200 projects are afoot at the Belarusian plant in Belarus (two units), El Dabaa in Egypt (four units), Hanhikivi in Finland (one unit), and Paks in Hungary (two units).

Leningrad II-2 replaces Leningrad I-2, a 925-MWe RBMK-1000 light water–cooled graphite-moderated reactor that permanently ceased operation in November 2020 after 45 years of service.

Newly connected Belarusian reactor powers down

On November 8, less than a week after becoming Belarus’s first nuclear reactor to be connected to the power grid, and only one day after a visit to the Belarusian site from the country’s president, Alexander Lukashenko, to celebrate the accomplishment, Belarusian-1 was forced to cease power production, a report from the Associated Press states.

Belarus on November 3 became the latest nation to begin generating electricity with nuclear energy when Unit 1 of the Belarusian nuclear plant was connected to the country’s power grid.

The Belarusian construction project, located in the Grodno region of Belarus, features twin 1,109-MWe pressurized water reactors, supplied by Rosatom, Russia’s state-owned nuclear energy corporation. The units are VVER-1200 Generation III+ designs, model AES 2006. Just last week, a VVER-1200 was connected to the Russian grid at the Leningrad plant.

The start-up program for Unit 1 began on August 7, when the first fuel assembly with fresh nuclear fuel was loaded into the reactor, according to a Rosatom press release. The reactor achieved first criticality on October 11.

Once fully completed, the plant is expected to supply approximately 18 billion kWh of low-carbon electricity to the Belarus national grid every year, Rosatom said.
