ZAPORIZHZHIA, Sept 2 (Reuters) - United Nations nuclear experts who crossed into Russian-held territory in Ukraine to assess the safety of Europe's biggest atomic energy plant were seeking on Friday to assess physical damage to the facility, where both sides warn of possible disaster.
An International Atomic Energy Agency (IAEA) inspection team braved intense shelling to reach the Zaporizhzhia nuclear power plant on Thursday. Russia and Ukraine say they fear a Chernobyl-like catastrophe due to shelling they blame on each other.
Russia seized the plant early in the now more than six-month-old war, and areas to the south are now the focus of a major Ukrainian counter-offensive. Kyiv accuses Moscow of using the facility to shield its forces, a charge Moscow denies while rejecting calls to withdraw troops.
After touring the plant on Thursday, IAEA chief Rafael Grossi said his inspectors were "not going anywhere". Grossi and other members of the team left for Ukrainian-held territory but five IAEA inspectors remain at the plant, Ukraine's state nuclear company says.
The inspectors will assess physical damage to the plant, ensure its safety and security systems are functional and evaluate the conditions of the facility's staff, the IAEA says. Grossi said on Thursday they would produce a report on their findings.
Since its capture by Russia in March, the plant has been controlled by Russian troops but operated by Ukrainian staff. On Thursday, one of its reactors was forced to shut down due to shelling.
In a video address late on Thursday, Ukrainian President Volodymyr Zelenskiy reiterated his frequent calls that all troops be removed from the plant -- a demand supported by Kyiv's Western allies and the United Nations.
"The main thing that must happen is the demilitarisation of the station's territory," Zelenskiy said. "Demilitarisation and full control of Ukrainian nuclear workers."
Russian Foreign Minister Sergei Lavrov said on Thursday Moscow was doing everything to ensure that the plant could operate safely, and for the IAEA inspectors to be able to complete their tasks.
Ukrainian Energy Minister German Galushchenko said on Thursday it was being discussed that certain IAEA specialists -- "up to two individuals" -- will be permanently stationed at the plant.
"But it is important for us that the station must be under national control, meaning that the station must be returned to the control of Ukraine," he told Ukraine's 1+1 television channel.
Several towns near the nuclear plant came under Russian shelling on Thursday, damaging homes and other buildings, Zaporizhzhia regional council mayor Mykola Lukashuk said. Reuters was unable to independently confirm this.
