Key facilities at a multipurpose nuclear research center in the high plains of Bolivia are nearing operation, and a ceremonial first concrete pour for the nuclear research reactor that will serve as the centerpiece of the project was held on July 26. Bolivian president Luis Arce attended the ceremony at the Center for Nuclear Technology Research and Development (CNTRD). Also attending were Kirill Komarov, first deputy director general for corporate development and international business at Rosatom (Russia’s state atomic energy agency), and authorities from the Ministry of Hydrocarbons and Energies and the Bolivian Nuclear Energy Agency (ABEN).

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.

Russia seeking customers for floating nuclear plants, report says

The Bellona news site is reporting that Rosatom is marketing its floating nuclear power plants to foreign countries. The news item noted on December 14 that Russia’s Tass newswire had published the information, citing government statements. Rosatom is Russia’s state nuclear corporation.

“Rosatom has made proposals for the installation of floating units to a number of foreign countries,” Yury Trutnev, a deputy prime minister and presidential representative to Russia’s Far Eastern Federal District, said earlier this month, according to Tass. “It’s clear that one unit is not enough for us to sell such modules. Their future replication would open a possibility for Russia to open a market niche where there currently is no one.”

Russian company Atommash has delivered the reactor pressure vessel for Unit 1 of the Akkuyu plant, the nuclear power facility under construction in Turkey, Akkuyu Nuclear JSC announced recently.

Atommash is a branch of AEM Technologies, which is part of Atomenergomash, the equipment-building division of Rosatom, Russia’s state atomic energy corporation. Akkuyu Nuclear, based in Ankara, was established to implement the Russian-Turkish project.

It took some three years to manufacture the 330-metric ton, 12-meter-long reactor pressure vessel and 20 days to transport it from the Atommash plant in Volgodonsk, Russia, to the eastern cargo terminal at the Akkuyu plant site, according to Akkuyu Nuclear.

Russia retires reactor at Leningrad plant

November 13, 2020, 9:31AMNuclear News

The Leningrad nuclear power plant’s Unit I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor, was permanently shut down on November 10, according to Rosatom, Russia’s state atomic energy corporation. The shutdown occurred at 12:30 a.m. Moscow time.

The unit was the oldest operating reactor at the plant, having achieved initial criticality in May 1975 and entered commercial operation in February 1976. Two additional RBMK-1000s remain in operation at Leningrad—Units I-3 and I-4, both of which have been in operation for about 40 years.

The retired reactor is to be replaced by Unit II-2, one of two 1,085-MWe Generation III+ VVER-1200 pressurized water reactors at the Leningrad site. The new unit was connected to the Russian grid in October, and on November 6 it received regulatory approval to begin pilot operation. (Leningrad’s other VVER-1200, Unit II-1, started commercial operation in 2018.) Following the trial operation, Unit II-2 will be shut down for an additional equipment inspection by a state commission before being put into commercial operation early next year, according to Rosenergoatom, Rosatom’s electric power division.

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.

TVEL develops new fuel for Hungarian reactors

October 15, 2020, 3:00PMNuclear News

TVEL Fuel Company, a division of Russian atomic energy corporation Rosatom, has completed a project to develop and validate a new nuclear fuel modification for the Paks nuclear power plant in Hungary, the company announced on October 13.

According to TVEL, the full package of modification documents has been handed over to MVM Paks Ltd., the plant’s operator, for further licensing of the new fuel by Hungary’s national nuclear power regulator. TVEL added that the project’s first fuel assemblies passed acceptance testing at the company’s Elemash Machine-Building plant, a fuel fabrication facility in Elektrostal, near Moscow.

The first consignment of the modified fuel is scheduled for delivery to Paks later this year. The contract between TVEL and MVM Paks for development of the new fuel was signed in late 2017.

U.S., Russia finalize amendment to uranium import agreement

October 7, 2020, 3:01PMNuclear News

The U.S. Department of Commerce and Rosatom, Russia’s state atomic energy corporation, have signed a final amendment to the Agreement Suspending the Antidumping Investigation on Uranium from the Russian Federation. The amendment extends the 1992 pact through 2040 and reduces U.S. reliance on uranium from Russia during that time period, the DOC announced October 6.

Previously, the agreement was set to expire on December 31 of this year. According to the DOC, the document’s expiration “would have resulted in unchecked imports of Russian uranium, potentially decimating the front-end of the nuclear fuel cycle in the United States.”

The final amendment is unchanged from the draft version, released for public comment on September 11. (For more specifics on the amendment, see our story on the draft here.)
