The regulator evaluated completed modernization efforts, equipment replacements, and ongoing plans to ensure the unit’s safe operation for the extended period. A key upgrade included the construction of a dedicated full-scale control room simulator building for Unit 1 over the past year. Previously shared with Unit 2, the new facility supports specialized training needs following the modernization program.
“The reliable operation of Kalinin NPP makes an important contribution to ensuring the energy security of central Russia and significantly influences the socio-economic development of the region and the living standards of the population,” said Viktor Ignatov, Director of the Kalinin nuclear power plant.
The Kalinin plant comprises four units. Units 1 and 2, both V-338 model VVER-1000 reactors, began commercial operation in 1985 and 1987, respectively. Units 3 and 4, V-320 model VVER-1000 reactors with a capacity of 950 MWe each, were commissioned in 2004 and 2012. Unit 1 previously received a 10-year license extension in 2014, allowing operation until 2025, supported by an earlier modernization program.
The latest extension reflects ongoing efforts to enhance the plant’s infrastructure, ensuring reliable and safe energy production. The Kalinin facility plays a vital role in supplying power to central Russia, supporting regional development and energy stability. The modernization and dedicated training infrastructure underscore the commitment to maintaining high safety and performance standards for the extended operational period.
