The IAEA team at Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) reported hearing hundreds of rounds of small arms fire last night, the latest sign of military activity potentially threatening nuclear safety and security, Director General Rafael Mariano Grossi said today.

The large number of shots – repeatedly fired for about an hour from 10pm local time – was unusual, the team members reported. ?

Conducting a site walkdown this morning, they saw numerous small calibre casings lying scattered on the ground near reactor units 5 and 6. There was no sign of broken windows or other physical damage.

The IAEA team at the ZNPP is seeking further information about the incident.

“Such military activity at or near a major nuclear power plant is clearly unacceptable,” Director General Grossi said. ?

Saturday evening’s shooting came after a series of purported attacks and other incidents involving drones near the ZNPP and other nuclear facilities in Ukraine in recent months, including a report of a strike a few days ago in the city of Enerhodar, where most ZNPP staff live. ?

Director General Grossi reiterated his deep concern about the apparent increased use of drones near nuclear power plants since early this year, saying such weaponry posed a clear risk to nuclear safety and security.

Any drone strike on a nuclear facility would violate the Seven Indispensable Pillars for nuclear safety and security during an armed conflict as well as the Five Principles to help ensure nuclear safety and security at the ZNPP, outlined by the Director General in March 2022 and May 2023, respectively. ?

“We are seeing a clear escalation in drone strikes during this war, also affecting Ukraine’s nuclear power plants and potentially putting them in further danger. As I have repeatedly stated, any military attack on a nuclear site – with or without drones – jeopardizes nuclear safety and must stop immediately,” Director General Grossi said.
