Ukrainian President Volodymyr Zelenskiy said Tuesday the situation at the Russian-occupied Zaporizhzhia nuclear power station had become critical, with Russian shelling preventing restoration of a power line needed to cool the reactors and prevent a meltdown. Rafael Grossi said there was no immediate danger as long as diesel generators remained in operation, providing emergency power for the facility. There has never before been such an emergency situation at the Zaporizhzhia plant. No terrorist in the world has ever dared to do with a nuclear power plant what Russia is doing now. IAEA monitors are stationed permanently at Zaporizhzhia and at Ukraine’s three other nuclear power stations.
