Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) remains reliant on one single off-site power line to receive the external electricity it needs to cool its six reactors and their spent fuel, some seven weeks after it lost the connection to its last back-up power line, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said today.
“The extremely fragile external power situation as well as challenges related to the availability of cooling water after the Kakhovka dam was destroyed two years ago underline the fact that nuclear safety remains highly precarious at the Zaporizhzhya Nuclear Power Plant. There are many important issues that must be addressed before it will be feasible to restart the plant,” Director General Grossi said.
The 330 kilovolt (kV) power line was disconnected on 7 May due to military activities some distance away from the ZNPP, leaving Europe’s largest nuclear power plant (NPP) dependent on one 750 kV line. Before the conflict, it had access to ten off-site power lines. Its six reactors have been in cold shutdown since 2024, but still require cooling water for their reactor cores.
Almost every day over the past week, the IAEA team based at the ZNPP has continued to hear explosions at various distances away from the site, a constant reminder of the close proximity to the frontline of the conflict.
The IAEA team has continued to conduct walkdowns across the site as part of the Agency’s mission to monitor and assess nuclear safety and security there.
Elsewhere in Ukraine, the IAEA teams at Ukraine’s three operating NPPs – Khmelnytskyy, Rivne and the South Ukraine – and the Chornobyl site reported hearing air-raid alarms over the past week. The teams at the Chornobyl site and the Rivne and South Ukraine NPPs have all rotated in recent days. Early on 21 June, the IAEA team at the South Ukraine NPP observed a drone around one kilometre from their hotel.
Two new deliveries of equipment have taken place under the IAEA’s comprehensive assistance programme for nuclear safety and security in Ukraine, bringing the total number of such shipments to 142 since the start of the armed conflict.
The State Enterprise Ukrainian Geological Company received portable radiation detection and monitoring devices within the framework of the IAEA Support and Assistance Mission to the Kherson Oblast (ISAMKO) programme in response to flooding caused by the destruction of the Kakhovka dam in mid-2023. The two deliveries were supported with funds from Japan.
