Drone Detonates Near South Ukraine Nuclear Plant, IAEA Issues Warning

Incident Near Pivdennoukrainsk

A drone was downed and subsequently detonated approximately 800 meters (875 yards) from the perimeter of the South Ukraine Nuclear Power Plant overnight on Wednesday into Thursday, September 25, 2025. The incident, which occurred near the city of Pivdennoukrainsk in Mykolaiv Oblast, led to an immediate warning from the International Atomic Energy Agency (IAEA). No casualties were reported, and the nuclear power plant itself sustained no direct damage.

IAEA Monitors Report Multiple Drones and Damage

According to a statement issued by IAEA Director General Rafael Grossi, the agency's team of monitors stationed at the site was informed that a total of 22 drones were observed within the plant's monitoring zone late on Wednesday and early Thursday. Some of these unmanned aerial vehicles reportedly flew as close as 500 meters to the facility.

IAEA monitors reported hearing gunfire and explosions around 1 a.m. local time. Following the detonation, they visited the impact site, where they observed a crater approximately four meters square and about one meter deep. Grossi noted that 'Nearby metal structures had been hit by shrapnel and the windows of vehicles close to the impact area were shattered.' A power line, though not connected to the nuclear plant, also came down.

Grossi Emphasizes Nuclear Safety Risks

Director General Grossi expressed grave concern over the incident, reiterating the constant dangers posed to nuclear safety during military conflicts. He stated, 'Once again, drones are flying far too close to nuclear power plants, putting nuclear safety at risk.' While acknowledging that 'Fortunately, last night's incident did not result in any damage to the South Ukraine Nuclear Power Plant itself,' Grossi warned, 'Next time we may not be so lucky.' He urged both sides of the conflict to 'show maximum military restraint around all important nuclear facilities.'

The South Ukraine Nuclear Power Plant is the country's second-largest nuclear power station, located approximately 350 kilometers south of Kyiv. It is part of the South Ukrainian Energy Complex. This event underscores ongoing concerns about the safety of nuclear infrastructure in Ukraine, a country that relies on nuclear power for more than half of its energy production.
