The International Atomic Energy Agency (IAEA) said Friday it was informed that a drone hit the cooling tower of a reactor unit at the Kursk Nuclear Power Plant in Russia.
A statement by the UN nuclear watchdog on US social media platform X said the drone hit the facility, located in the Kursk region bordering Ukraine, early Thursday, but did not specify who informed the IAEA of the incident.
“It was reported that the unit was operating at the time, but its operating mode did not change and there was no fire,” it said.
Quoting IAEA chief Rafael Grossi, the statement said that all attacks on nuclear facilities are “unacceptable” as they could “endanger nuclear safety and security, irrespective of where they occur.”
Grossi reiterated demands for “maximum military restraint” to prevent the risk of a nuclear accident.
The IAEA did not provide details on the source of the drone or circumstances surrounding the incident.
The agency has regularly warned Moscow and Kyiv about dangers to nuclear safety amid the Russia-Ukraine war, which began in February 2022.
In a later statement, Russia’s nuclear state corporation Rosatom confirmed that a drone detonated upon striking the cooling tower of the plant’s no. 1 power unit, causing “minor damage.”
It stated the incident did not affect the facility’s operations and that power unit no. 1 continues to operate at 100% capacity.
“The safety of the plant’s operation is ensured. Radiation levels remain unchanged and consistent with natural background values,” it added.
