IAEA: Informed that Zaporizhzhia nuclear power plant today lost off-site power for 21st time during military conflict
The International Atomic Energy Agency (IAEA) has confirmed that the Zaporizhzhia nuclear power plant lost all off-site power today, marking the 21st such incident since the start of the military conflict in Ukraine. The plant, Europe’s largest nuclear facility, relies on external power to operate essential safety systems, including cooling mechanisms for its six reactors and spent fuel pools. In response to the outage, emergency diesel generators have been activated to maintain critical operations.
This latest disruption underscores the ongoing fragility of the plant’s power infrastructure, which has been repeatedly damaged due to military activity in the region. The IAEA has previously emphasized that loss of off-site power remains one of the most significant risks to nuclear safety at the facility. The agency’s director-general, Rafael Grossi, has described repeated power outages as “deeply concerning,” warning that they increase the likelihood of a nuclear accident.
The Zaporizhzhia plant has been under Russian military control since March 2022, and both sides have accused each other of damaging the plant’s infrastructure. The IAEA has maintained a monitoring presence at the site since September 2022 and continues to advocate for a nuclear safety and security protection zone around the facility.
The plant’s reliance on emergency diesel generators highlights the precarious nature of its operations. While fuel reserves are sufficient for approximately 20 days of continuous use, the repeated need for backup power raises concerns about long-term sustainability and human error under prolonged stress. The IAEA has also noted that staffing levels have been significantly reduced, further complicating efforts to maintain safety standards.
The situation at Zaporizhzhia remains a focal point in broader peace negotiations, with both Ukraine and Russia proposing frameworks for the plant’s future. Ukraine has consistently called for full withdrawal of Russian forces, while Russia has suggested joint management or integration into its power grid.
As the IAEA continues to monitor the situation, the international community remains attentive to the potential implications of further disruptions at the plant. The 21st loss of off-site power serves as a stark reminder of the risks posed by the ongoing conflict and the urgent need for a resolution to ensure the safety and security of the facility.
