The head of the UN nuclear watchdog said a cooling tower at Ukraine's Russian-occupied Zaporizhzhya nuclear power plant had been badly damaged in a fire last month and would probably have to be demolished. Rafael Grossi, director-general of the International Atomic Energy Agency, made the comment on September 4 during a visit to the plant. "Until today, we hadn't been able to get to this point, high up in the tower, so we can assess in a much better way the damage that occurred," Grossi said in a video he posted on X, formerly Twitter. "This big structure is not usable in the future, so it will probably be demolished at some point."
