Ukrainian engineers have restored "much needed" back-up power to a key Russian-occupied nuclear power plant after shelling robbed it of access to external electricity twice in the past week, the head of the U.N. nuclear watchdog said on Friday.
Rafael Grossi, director general of the International Atomic Energy Agency, said the operating staff at the Zaporizhzhia nuclear plant, "working in very challenging conditions," were doing everything they could to bolster the plant's off-site power, essential for ensuring nuclear safety.
