Many incidents occurred at various power plants operating the RBMK reactor. Most of them were covered up by the USSR government. [citation needed] These are some of the known incidents at the RBMK reactors: Explosion of a tank holding radioactive gases at the Leningrad unit 1 in January 1975; Partial meltdown at Leningrad unit 1 in 1975
In recent decades, construction was started on reactor projects all across the country using the newer VVER class of reactors. In some cases, complications with supply, export security and a variety of other factors have led to the suspension of construction or even permanent cancellation of these projects entirely.
The first Kursk RBMK reactor shut down in December 2021, while the first Kursk II unit was expected to be commissioned by the end of 2022, and the second unit in 2023. In January 2023, the 235-tonne steel dome was set on the unit 1 containment building, where it will serve as a key barrier between the reactor and the environment. This lift ...
The plant has four nuclear reactors of the RBMK-1000 type, all of which are first generation units similar to that of Kursk and Chernobyl units 1 and 2. Each unit has a separate reactor building but the turbine hall is shared between 2 reactors. [2] In 2008, construction started on Leningrad II with 2 VVER-1200 type reactors. They will ...
The Chernobyl Nuclear Power Plant [a] (ChNPP) is a nuclear power plant undergoing decommissioning.ChNPP is located near the abandoned city of Pripyat in northern Ukraine, 16.5 kilometers (10 mi) northwest of the city of Chernobyl, 16 kilometers (10 mi) from the Belarus–Ukraine border, and about 100 kilometers (62 mi) north of Kyiv.
The three sites (Kursk I, Leningrad I, Smolensk I) which all consist of 3+ RBMK reactors are going to be replaced with VVER-1200 units at Leningrad and VVER-TOI units at Smolensk (2 units are already in pre-construction phase with planned completion in 2033 - each rated at 1250 MW per unit - out of a total of 4 units announced) [12] and Kursk ...

By 2013 about 75% of still operating U.S. reactors had been granted life extension licenses to 60 years. [5] Chernobyl's No.4 reactor that exploded was a generation II reactor, specifically RBMK-1000. Fukushima Daiichi's three destroyed reactors were generation II reactors; specifically Mark I Boiling water reactors (BWR) designed by General ...
