UN atomic watchdog chief Rafael Grossi has said he plans to issue a report on the safety of the Russian-held Zaporizhzhia nuclear power plant in Ukraine early next week.
Speaking at a news conference upon his return to Vienna, Mr Grossi said six International Atomic Energy Agency staff members remain at Zaporizhzhia, Europe's largest nuclear plant, after he led a 14-person mission there.
He added that the number would be reduced to two next week and those two would be the IAEA's continuous presence there in the longer term.
Mr Grossi said he was able to see everything that he asked to see at the Russian-occupied site, adding that the troops there did not approach his team, nor were they available to them.
The Ukrainian army said the Russian forces there had removed "all their equipment" from the site of what is Europe's largest nuclear plant, before the UN team arrived on Thursday.
Russian troops seized control of the site in early March.
There have been repeated attacks in the vicinity but both Moscow and Kyiv have denied responsibility.
A shelling attack on the area at dawn on Thursday forced one of the plant's six reactors to close.
Ukraine's Energoatom nuclear agency said it was "the second time in 10 days" that Russian shelling had forced the closure of a reactor.
Mr Grossi said yesterday the site had been damaged by the fighting in Ukraine.
"It is obvious that the plant and physical integrity of the plant has been violated several times," he said.
Amid the visit, Ukraine's military said it had carried out strikes against Russian positions in the region around the southern town of Enerhodar, near the Zaporizhzhia plant.
The revelation by the armed forces' general staff was unusual, since the military rarely gives details of specific targets.
"It has been confirmed that in the region around the towns of Kherson and Enerhodar, precise strikes by our armed forces destroyed three enemy artillery systems as well as a warehouse with ammunition and up to a company of soldiers," the general staff said in a Facebook post.
It did not give more details about the strikes. Kherson is about 300km south-west of Enerhodar.
Russia has repeatedly accused Ukraine of shelling the nuclear power plant. Kyiv rejects the charge, saying pro-Moscow forces are responsible for attacking the facility.
