IAEA-Brokered Ceasefire Restores Critical Power To Zaporizhzhya Nuclear Plant

A vital external power line feeding the Russian-held Zaporizhzhya nuclear power plant in Ukraine was restored on Monday after nearly three weeks offline, the International Atomic Energy Agency (IAEA) said.

What Happened

The UN nuclear watchdog, speaking from Vienna, said technicians repaired a damaged transmission line during a localized ceasefire that the IAEA helped broker. The restoration reconnected the plant to an external electricity source that is essential to safety systems.

Why It Matters

The Zaporizhzhya plant—Europe's largest nuclear power station—depends on stable external power to cool radioactive material and to run other critical safety systems. Its last remaining external line was damaged during fighting on August 20, leaving the facility reliant on emergency diesel generators.

"This repair is a crucial step to reduce the risk of a nuclear accident," IAEA Director General Rafael Grossi said, underlining the urgent danger of a total power loss if generator fuel had been exhausted.

The IAEA warned that fuel supplies for the on-site diesel generators had been running low in recent days, and without the repaired transmission line the plant could have faced a complete loss of power with severe safety implications.

Context

The Zaporizhzhya site fell under Russian control soon after Moscow launched its full-scale invasion of Ukraine. All six reactors at the plant are currently shut down and are not producing electricity. Before the conflict, the station was supplied by 10 external power lines that provided redundancy for cooling and other vital systems.

The IAEA continues to monitor the plant's status and has called for ongoing, unimpeded access and continuous, reliable power to ensure nuclear safety.
