The personal supervision of repair work at the Zaporizhzhia power plant by experts from the International Atomic Energy Agency (IAEA) represents a new attempt to reduce the risks associated with nuclear safety in an area affected by military conflict. According to the IAEA, this work began after the organization brokered the conclusion of a local ceasefire agreement between the armed forces of Ukraine and Russia, the purpose of which is to restore the necessary electricity supply for the operation of Europe’s largest nuclear power plant in a territory occupied by Russia.
The international organization led by Rafael Grossi announced that interventions on the power lines next to the Zaporizhzhia plant began this Sunday to contribute to the operational stability of the nuclear power plant. According to the IAEA, work to restore energy transmission is expected to take several days, while the agency’s technical team is constantly monitoring the development of activities. Grossi publicly thanked both parties for their willingness to agree on a temporary ceasefire that would allow the implementation of these important tasks of restoring the electrical connection between the Zaporizhzhia distribution yards and the nearby thermal power plant. “Significant repairs to power lines near the Zaporizhzhia nuclear power plant have begun following another local ceasefire mediated by the IAEA,” the official said, according to the IAEA itself. At the time of publication, neither the Ukrainian nor Russian authorities made official statements about this agreement on the suspension of hostilities.
The energy situation around the Zaporizhzhia nuclear power plant has experienced repeated episodes of constant disruption since March 2022, the date the plant came under Russian control. As published by the IAEA, Rafael Grossi warned on December 11 that ongoing instability in Ukraine’s national power grid, a direct result of the armed conflict following the Russian invasion, exposes the nuclear power plant and its surroundings to a level of risk that is testing nuclear safety. The agency confirmed that another supply outage occurred at the power plant on December 6, showing the fragility of the energy infrastructure.
In another statement, the IAEA reported that on December 13, a power interruption to the power plant was again recorded due to recent bomb attacks in the area. Although exact data on the extent of the damage has not been publicly released, the plant has already experienced twelve complete power shutdowns since the war began in February 2022. Each of these incidents heightens concerns about the potential consequences for nuclear safety, as a repeatedly shut down plant relies on backup power sources to keep reactors cool and avoid emergency situations.
Russia and Ukraine accuse each other of being responsible for military actions that hit the nuclear power plant’s infrastructure, including the power grids and transmission systems connected to both the nuclear power plant and the Zaporizhzhia thermal power plant. This struggle makes repair work more difficult and hinders the ability to find lasting solutions to stabilize energy supplies. According to the IAEA, the organization maintains its presence at the facility and continues to broker diplomatic engagements with both parties with the aim of facilitating technical cooperation on nuclear issues and preventing major incidents.
The start of ongoing repairs is the latest step in a series of efforts to reduce the facility’s vulnerability. IAEA sources emphasize the relevance of the agreement reached, as minimum security conditions can only be achieved through the introduction of pauses in fighting. Restoring electrical connections is one of the most urgent technical priorities for the power plant’s operators, both on the Ukrainian side and under Russian occupation. According to the same international organization, repeated interruptions expose the power plant to possible nuclear incidents not only due to the loss of energy, but also due to the difficulty of timely access to spare parts and essential materials during a prolonged armed conflict.
As specialized teams work under international supervision to restore power, nuclear and humanitarian security risks remain in the region. The IAEA confirmed that it will continue to monitor the situation and report on the progress of repair work and any further developments that may affect the safe operation of the Zaporizhzhia nuclear power plant.
