Europe’s largest nuclear power plant loses its last external power connection again, forcing emergency diesel generators to keep its reactors cool

Russia seized Europe’s largest nuclear power plant during the opening weeks of its 2022 invasion. Its external power connections have repeatedly been damaged by fighting. On October 23, repairs were completed on the Ferosplavna-1 line, which had become the plant’s only remaining external power connection. Today, that same line disconnected again, forcing the plant to rely on emergency diesel generators to cool its nuclear fuel. The IAEA says the cause and location of the latest disconnection are unknown. The available fuel can run the generators for approximately 2 weeks.
