Zelenskiy: Ukraine narrowly escaped nuclear catastrophe

STORY: Zelenskiy said Russian shelling on Thursday sparked fires in the ash pits of a nearby coal power station that disconnected the reactor complex, Europe's largest such facility, from the power grid.

Back-up diesel generators ensured power supply that is vital for cooling and safety systems at the plant, he said, praising the Ukrainian technicians who operate the plant under the gaze of the Russian military.

"If our station staff had not reacted after the blackout, then we would have already been forced to overcome the consequences of a radiation accident," he said in an evening address.
