Zelenskyy warns Russian drones endanger safety at Chernobyl and at Europe's biggest nuclear plant

Russia's continued attacks on Ukraine's power grid are raising concerns about nuclear safety. Ukraine President Volodymyr Zelenskyy says that a drone attack cut power for over three hours to the site of the 1986 Chernobyl nuclear disaster. He says Europe’s largest atomic power plant, Zaporizhzhia, remains disconnected from the grid after more than a week due to Russian shelling. Both facilities need constant power for cooling systems. On Wednesday, Zelenskyy criticized the U.N. watchdog for weak responses to the threats. The Zaporizhzhia plant has been off the grid for over a week, relying on emergency generators. The U.N. nuclear agency says the plant is not in immediate danger.
