Ukraine - World Nuclear Performance Report
All 15 reactors in Ukraine are VVER units. Rovno and Khmelnitski are in the west of the country, and South Ukraine and Zaporizhzhia in the south.
Since January 2023 teams of nuclear safety and security experts from the International Atomic Energy Agency (IAEA) have been stationed at Ukraine’s nuclear power plants and the Chernobyl site. All units at Zaporizhzhia – which is occupied by Russian military forces – have not generated electricity since September 2022, and have been in cold shutdown since April 2024.
In June 2024 IAEA Director General Rafael Mariano Grossi said there “was an understanding” that the Zaporizhzhia plant’s reactors would not be restarted during the conflict. In April 2025 the current director of Zaporizhzhia, Yuriy Chernichuk, said that he expects Russian licences for operation of all units to be obtained by the end of 2027. Ukraine in response said that any talk of restarting the units is a violation of nuclear and radiation safety standards.
Despite the ongoing conflict, Ukraine has taken steps to move forward with plans for new nuclear capacity. In August 2024 Energoatom said it had land transferred to it as part of steps which could lead to a new four-unit nuclear power plant at the Chyhyryn site. In March 2025 Ukraine’s president signed a law to facilitate the purchase of equipment from Bulgaria’s discontinued Belene project
for use in the two part-built units at Khmelnitsky.
