RUSSIAN MISSILES have knocked out roughly half of Ukraine’s pre-war electricity-generation capacity. But because Russia has refrained from blowing up nuclear reactors, nearly 60% of Ukraine’s electricity production is currently nuclear—even though the country’s (and Europe’s) biggest plant, in Zaporizhia, was occupied by Russia in 2022 and is now shut down. Without nuclear reactors, says German Galushchenko, the energy minister, Ukraine’s grid “would not survive”. In what would be a first for a country under assault, Ukraine now aims to install more of them.
