Photo: RosenergoatomThe first of 163 nuclear fuel assemblies has been loaded into Leningrad II-2, marking the beginning of the Generation III+ unit’s physical startup, Rosenergoatom announced on July 19.The electric power division of Rosatom, Russia’s state-owned atomic energy corporation, Rosenergoatom is the operator of all of Russia’s nuclear power plants. The fuel for Leningrad II-2, a 1,085-MWe VVER-1200 pressurized water reactor, was manufactured at the Novosibirsk Chemical Concentrates Plant, part of Rosatom subsidiary TVEL.What they’re saying: “The startup is only the first step; we have a long way ahead of us,” said Vladimir Pereguda, director of the Leningrad plant. “This autumn, we will connect the unit to the grid and generate the first kilowatt hours of electricity, gradually mastering the reactor power levels up to 100 percent. At the same time, we will carry out hundreds of tests to confirm the reliable and safe operation of all technological systems and the safety system of the unit, so that at the beginning of 2021 we will put a new unit into commercial operation.”More specifically: After fuel is loaded, the reactor will be brought to the minimum controllable power level (up to 1 percent), according to Rosenergoatom. The physical startup should last until September, at which time power startup will commence, to be followed by trial operation and integrated testing, the company said. The new unit will replace Leningrad I-2, a 925-MWe RBMK-1000 light-water-cooled graphite-moderated reactor that is scheduled to permanently cease operation at the end of this year, after 45 years of service.Background: The VVER-1200 is the world’s only Generation III+ design in serial construction, according to Rosatom. The new Leningrad unit will be the fourth in the series, following Novovoronezh II-1 and -2, launched in 2016 and 2019, respectively, and Leningrad II-1, launched in 2017.Earlier this month, Rosenergoatom announced that preparations have begun for the construction of two more VVER-1200 units at the Leningrad site.Tags:leningradrbmk-1000rosatomrosenergoatomtvelvver-1200Share:LinkedInTwitterFacebook
Russia seeking customers for floating nuclear plants, report saysTechnicians loading the first reactor aboard the Akademik Lomonosov, Russia's floating nuclear power plant. Credit: Rosatom.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.”Go to Article
Russia retires reactor at Leningrad plantThe 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.Go to Article
