Ukrainian President Volodymyr Zelenskyy has warned that the situation at the Zaporizhzhia nuclear power plant is “critical” as the facility has been without power for seven days. One of the diesel generators providing emergency power to the plant is no longer working, Zelenskyy said, a week after external power lines went down. No terrorist in the world has ever dared to do with a nuclear power plant what Russia is doing now.”The outage is the longest the Russian-occupied plant has gone without power since Moscow’s full-scale invasion of Ukraine in February 2022. But the plant needs power to maintain cooling and safety systems, which prevent reactors from melting – a danger that could set off a nuclear incident. “Neither side would benefit from a nuclear accident.”IAEA monitors are stationed permanently at Zaporizhzhia and at Ukraine’s three other nuclear power stations.
