Ukraine and Russia have agreed a temporary ceasefire to allow urgent repair work on a damaged power line at Europe’s largest nuclear plant, the Zaporizhzhia Nuclear Power Plant (ZNPP), IAEA officials confirmed today……….

The 330 kV backup line was disconnected on 2 January during military activity, leaving the plant reliant on a single 750 kV main power line. Technicians from Ukraine’s electrical grid operator are expected to begin repairs under the short-term truce in the coming days.

An IAEA team has departed Vienna to travel to the frontline and monitor the work, ensuring that safety measures are strictly followed during the repairs.

The agency confirmed that winter protection measures are in place at the plant, including temperature controls to prevent freezing in groundwater wells that supply cooling systems for reactors and spent fuel pools. Emergency diesel generators are also fully operational should the plant lose off-site power again.

The situation highlights the ongoing risks to Ukraine’s nuclear facilities, with military activity recently damaging a substation at the Chernobyl plant and forcing temporary power reductions at other sites.

Grossi warned that attacks on Ukraine’s power infrastructure have “direct implications on the nuclear safety of its nuclear facilities” and announced plans for another IAEA mission to assess 10 critical substations supplying electricity for reactor cooling systems and safety equipment.

Over the past week, IAEA teams reported air raid alarms and military activity near all five nuclear sites in Ukraine, including explosions and flying objects close to Zaporizhzhia, Khmelnitsky, South Ukraine, and Chernobyl plants.

The temporary ceasefire now allows repairs to the ZNPP backup line to go ahead, providing a vital safeguard for Europe’s largest nuclear facility and reducing the risk of a serious nuclear incident. https://www.mirror.co.uk/news/world-news/ukraine-russia-agree-temporary-ceasefire-36566368
