All six reactors of the Zaporizhia Nuclear Power Plant (ZNPP), for the first time since the end of 2022, have been transferred to cold shutdown, Director General of the International Atomic Energy Agency (IAEA) Rafael Grossi said in a statement published on the agency's website on April 13.

"All six reactor units of Ukraine's Zaporizhzhya Nuclear Power Plant (ZNPP) are now in cold shutdown for the first time since late 2022... In line with the ZNPP's plans, previously reported by the IAEA, the plant started transitioning unit 4 from hot to cold shutdown on Friday morning, a process that was completed at 7:30am today," the IAEA said.

"The decision to have all six units in cold shutdown is positive in itself, as the cooling down of the reactor provides an additional buffer in case of an accident. But it doesn't address the fundamental issue of a recent sharp deterioration of the situation at the plant. Without a doubt, nuclear safety and security at this major nuclear facility remains very precarious," Grossi said.
