The Russian nuclear regulator Rostekhnadzor has issued a location licence to Rosenergoatom, a subsidiary of Rosatom, for the proposed 1.3 GW fourth unit of the Kursk-II nuclear power plant, located in western Russia near the Ukrainian border. This approval will allow preparatory work to begin for the construction of the reactor. Earlier in March 2025, Rostekhnadzor had also issued a location licence for unit 3 (1.3 GW) of the power plant.
The Kursk-II nuclear plant will feature four VVER-TOI reactors. Construction of the first unit at the site began in 2018, while construction of the second unit started in 2019. Both units are expected for completion in 2025. Kursk-II will replace the original Kursk nuclear power plant, for which all four RBMK-1000 units are scheduled to be decommissioned by 2031. Unit 1 of Kursk was shut down in December 2021, while Unit 2 was retired in February 2024.
At the end of 2023, about 11% of Russia’s installed capacity was nuclear power (29.5 GW) and nuclear accounted for around 19% of the power mix.
