‘Playing with fire’ UN warns as team to inspect damage at Ukraine nuclear plant

The head of the UN nuclear watchdog has warned that whoever fired artillery at Ukraine's Zaporizhzhia nuclear power plant was "playing with fire" as his team prepared to inspect it on Monday for damage from the weekend strikes.

The attacks on Europe's biggest nuclear power plant in the south of Ukraine came as battles raged in the east, where Russian forces pounded Ukrainian positions along the front line President Volodymyr Zelensky said.

The shelling of the Zaporizhzhia nuclear power station follows setbacks for Russian forces in the Kherson region in the south and a Russian response that has included a barrage of missile strikes across the country, many on power facilities.

The International Atomic Energy Agency (IAEA) said more than a dozen blasts shook the nuclear plant late on Saturday and on Sunday. IAEA head Rafael Grossi said the attacks were extremely disturbing and completely unacceptable.

IAEA head Rafael Grossi said the attacks were extremely disturbing and completely unacceptable.

"Whoever is behind this, it must stop immediately. As I have said many times before, you're playing with fire!" Grossi said in a statement.

Russia and Ukraine blamed each other for the shelling of the facility, as they have done repeatedly in recent months after attacks on it or near it.

Citing information provided by plant management, an IAEA team on the ground said there had been damage to some buildings, systems and equipment, but none of them critical for nuclear safety and security.

The team plans to conduct an assessment on Monday, Grossi said, but Russian nuclear power operator Rosenergoatom said there would be curbs on what the team could inspect.

"If they want to inspect a facility that has nothing to do with nuclear safety, access will be denied," Renat Karchaa, an adviser to Rosenergoatom's CEO, told the Tass news agency.

Repeated shelling of the plant has raised concern about a grave accident just 500 km (300 miles) from the site of the world's worst nuclear accident, the 1986 Chornobyl disaster.

The Zaporizhzhia plant provided about a fifth of Ukraine's electricity before Russia's invasion, and has been forced to operate on back-up generators a number of times. It has six Soviet-designed VVER-1000 V-320 water-cooled and water-moderated reactors containing Uranium 235.

The reactors are shut down but there is a risk that nuclear fuel could overheat if the power driving the cooling systems is cut. Shelling has repeatedly cut power lines.

Russia's defence ministry said Ukraine fired shells at power lines supplying the plant but Ukraine's nuclear energy firm Energoatom accused Russia's military of shelling the site, saying the Russians had targeted infrastructure necessary to restart parts of the plant in an attempt to further limit Ukraine's power supply.
