IAEA Seeks Cease-Fire Window After Zaporizhzhia Plant Loses Main Grid Line

Overview

• The disconnection that hit the Dniprovska 750 kV line Tuesday has left the Zaporizhzhia plant dependent on the Ferosplavna-1 330 kV backup.
• Director General Rafael Mariano Grossi has asked Russia and Ukraine to pause local fighting to let crews assess damage and plan repairs, with timing still unclear.
• The IAEA team on site remains in contact with plant staff and Ukraine’s grid dispatcher and is closely tracking conditions during the outage.
• Even with reactors shut down, spent fuel and reactor cores still need powered cooling pumps, so losing redundancy raises the risk of a shift to emergency diesel generators.
• Five earlier IAEA-brokered local truces enabled six power-line fixes, and Russian officials now cite the plant’s wartime experience as a template for protecting Iran’s Bushehr site after a strike nearby on March 24.
