Ukraine and Russia paused fighting to repair a key power line at the Zaporizhzhia nuclear plant, the IAEA confirmed.

Ukraine and Russia have agreed to a temporary ceasefire to repair a damaged 330 kV backup power line at the Zaporizhzhia Nuclear Power Plant, the largest in Europe, following a January 1 attack. The IAEA confirmed the fourth such truce brokered since 2022, with Ukrainian technicians set to conduct repairs under monitoring. The plant, under Russian control since 2022, now relies on a single main power line, heightening safety risks. Emergency diesel generators remain operational, and winter protections are in place to prevent freezing. The IAEA is assessing 10 critical substations supplying cooling systems, as recent attacks disrupted power at multiple nuclear sites, including Chernobyl.
