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.

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.

Rosenergoatom, the electric power division of Russia’s state-owned nuclear power corporation Rosatom, announced on October 23 that Leningrad II-2 has been connected to the grid. The unit is one of two Generation III+ VVER-1200 pressurized water reactors at the Leningrad nuclear plant.

The reactor will replace Leningrad I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor that will permanently cease operation at the end of 2020 after 45 years of service. Fuel loading at Leningrad II-2 began in July, and initial criticality was achieved in August. Following the trial operation, the unit 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.
