Ukraine and Russia have agreed to a temporary ceasefire for urgent repairs on a damaged power line at the Zaporizhzhia Nuclear Power Plant (ZNPP), Europe’s largest nuclear facility, as confirmed by officials from the International Atomic Energy Agency (IAEA) today.
The IAEA, a UN agency responsible for overseeing nuclear facilities to prevent accidents and promote safety, has reported that the 330 kV backup line at the ZNPP was disabled on January 2 due to military activities. This left the plant dependent on a single 750 kV main power line. Technicians from Ukraine’s electrical grid operator are set to commence repairs under the agreed-upon truce in the coming days.
A team from the IAEA has left Vienna to monitor the repair work on-site, ensuring strict adherence to safety protocols during the process.
Rafael Mariano Grossi, the Director General of the IAEA, emphasized the critical role the agency plays in negotiating such ceasefires to maintain nuclear safety. He stated, “This temporary ceasefire, the fourth we have negotiated, demonstrates the indispensable role that we continue to play. The IAEA continues to work closely with both sides to ensure nuclear safety at the ZNPP and to prevent a nuclear accident during the conflict.”
Winter safeguards are in place at the ZNPP, including measures to prevent freezing in groundwater wells supplying cooling systems for reactors and spent fuel pools. Additionally, emergency diesel generators are operational in case of another power loss.
The recent damage to Ukraine’s nuclear facilities due to military actions, including an incident at the Chernobyl plant leading to temporary power reductions, underscores the ongoing risks faced by these critical sites.
Grossi cautioned that attacks on Ukraine’s power infrastructure directly impact nuclear safety and announced plans for an IAEA mission to evaluate 10 key substations supplying power for reactor cooling and safety systems.
IAEA teams have reported incidents of air raid alarms and military operations near all five nuclear sites in Ukraine over the past week, including activity close to Zaporizhzhia, Khmelnitsky, South Ukraine, and Chernobyl plants.
The temporary ceasefire paves the way for much-needed repairs to the ZNPP backup line, enhancing safety at Europe’s largest nuclear plant and mitigating the risk of a potential nuclear incident.
