Ukraine and Russia have reached an agreement on a temporary ceasefire to facilitate urgent repairs on a damaged power line at the Zaporizhzhia Nuclear Power Plant (ZNPP), which is the largest nuclear facility in Europe, as confirmed by officials from the International Atomic Energy Agency (IAEA) today.
The IAEA, a United Nations agency responsible for monitoring nuclear facilities and ensuring the safe and peaceful use of nuclear energy, plays a crucial role in preventing accidents and promoting safety.
Following the disconnection of the 330 kV backup line on January 2 due to military activities, the ZNPP has been relying on a single 750 kV main power line. Technicians from Ukraine’s electrical grid operator are set to commence repairs under a short-term truce in the coming days.
A team from the IAEA has departed from Vienna to oversee the repair work on the frontlines, ensuring strict adherence to safety protocols during the maintenance process.
IAEA Director General Rafael Mariano Grossi emphasized the significance of the temporary ceasefire, marking the fourth negotiated ceasefire, underlining the agency’s crucial role in maintaining nuclear safety at the ZNPP and preventing nuclear incidents during the conflict.
Winter protection measures, including temperature controls to prevent freezing in groundwater wells that supply cooling systems for reactors and spent fuel pools, are in place at the plant. Emergency diesel generators are also operational in case of a loss of off-site power.
The recent damage to a substation at the Chernobyl plant due to military actions underscores the ongoing risks faced by Ukraine’s nuclear facilities. Grossi expressed concerns over attacks on Ukraine’s power infrastructure, stating that they directly impact the safety of nuclear facilities. Plans are underway for another IAEA mission to assess critical substations supplying electricity for reactor cooling systems and safety equipment.
IAEA teams have reported air raid alarms and military activities near all five nuclear sites in Ukraine over the past week, including incidents near Zaporizhzhia, Khmelnitsky, South Ukraine, and Chernobyl plants.
The temporary ceasefire paves the way for the essential repairs on the ZNPP backup line, ensuring the safety of Europe’s largest nuclear facility and reducing the risk of a severe nuclear incident.
