IAEA Chief Expresses Concern Over 12-Hour Communication Loss at Zaporozhye Nuclear Plant

The International Atomic Energy Agency (IAEA) has expressed serious concern over a nearly 12-hour communications blackout at the Zaporozhye Nuclear Power Plant (ZNPP) on May 27, 2026. Director General Rafael Grossi described the incident as "clearly a very concerning event in terms of nuclear safety and security," noting that the agency's team of experts at the site and the plant itself were unable to communicate with the outside world during this period. The IAEA stated it would investigate the cause of the blackout and work to prevent similar incidents in the future. The communication loss occurred following a Ukrainian military attack on Energodar, the city adjacent to the nuclear facility, which resulted in disruptions to communications infrastructure and partial power outages in the area. No casualties were reported in the attack. The incident reflects ongoing tensions in the region, with Energodar facing regular attacks from Ukrainian Armed Forces. According to the IAEA, the frequency of attacks on the area has increased significantly in May 2026 compared to earlier months of the year.
