Attacks on the Zaporozhye nuclear power plant (ZNPP), Europe’s largest facility of its kind, are “unacceptable,” Rafael Grossi, the Director General of the International Atomic Energy Agency (IAEA), has stated.

His remark came shortly after Russian authorities in the eponymous region reported multiple drone strikes on the ZNPP, blaming the Ukrainian military. Moscow has repeatedly accused Kiev of targeting the facility in the past.

The power plant was brought under Russian control in March 2022, shortly after which the region’s residents voted in a referendum to join Russia, which Ukraine has dismissed as a sham. Around the same time, the IAEA deployed a monitoring mission to the ZNPP, which has remained in-situ to date.

Speaking to reporters at Khrabrovo Airport in Russia’s Kaliningrad Region on Friday, Grossi insisted that “any attack on any nuclear power plant, in particular [the] Zaporozhye [NPP], is absolutely unacceptable.”

He stopped short of apportioning the blame for such incidents to either Ukraine or Russia, noting that the IAEA’s mandate is purely technical in nature.

Grossi argued, however, that the fact that the international watchdog is monitoring the situation and recording any attacks, is meant to act as a deterrent.

He was in Kaliningrad for a meeting with the CEO of Russia’s state-run nuclear corporation, Rosatom, Aleksey Likhachev, who described the talks as the
“most multifaceted and meaningful” to date, during a press conference on Friday.

He emphasized the importance of IAEA’s mission at the Zaporozhye Nuclear Power Plant, noting how it provides an “information window for the whole world into the real state of affairs.” This helps fight “provocations [and] fakes.”

In a statement on Thursday, the IAEA chief reported that the watchdog’s team stationed at the facility had “heard repeated rounds of gunfire that appeared to be aimed at drones reportedly attacking the site’s training center, followed by the sound of multiple explosions.”

Grossi stressed that “it was the fourth time this year that the training center, located just outside the site perimeter, was reportedly targeted by unmanned aerial vehicles.”

Drone attacks on the ZNPP “must stop immediately,” he insisted, warning of “potentially serious consequences.”

Also on Thursday, a statement appeared on the ZNPP’s Telegram channel, claiming the Ukrainian military had conducted multiple drone attacks on the training center located on the facility’s grounds, with no casualties or significant damage reported.
