One out of the six nuclear reactors at the Zaporizhzhia power plant is operational, the head of the Russian-backed administration in occupied parts of Zaporizhzhia said.

"One power unit remains in operation on Friday at the Zaporizhzhia nuclear power plant, delivering 60% of its capacity," said Yevgeny Balitsky, according to the Russian state news agency RIA Novosti.

Until recently, two reactors were providing power.

Balitsky said his administration had shown details of alleged Ukrainian shelling in the area to the UN nuclear inspectors that visited the plant Thursday .

The team from the International Atomic Energy Agency (IAEA) "recorded all the objects we showed. ... They said ‘we don’t give assessments of the military situation.’ … They recorded the incoming shells, they are in the protocols, the hits, we showed them everything," he said, adding that the Russian-backed authorities were interested in the IAEA's official view on the operation of the plant and the shelling.

This comes as Ukrainian and Russian agencies continue to accuse each other of trying to subvert the mission of the IAEA to safeguard the Zaporizhzhia nuclear power plant.

Ukraine accused the Russians of trying to prevent the IAEA mission from getting to know the facts on the ground, which it said will make it difficult for the agency to "make an impartial assessment."

"The Russian military lies, manipulates and misrepresents reality at Zaporizhzhia NPP by disseminating only information on the IAEA mission visit it could benefit from," The Ukrainian nuclear power provider, Energoatom, said Friday.

On the other hand, pro-Russian officials in the occupied area are blaming the Ukrainians for impeding the IAEA's work. An official said that Ukraine "did not stop" shelling "but their intensity significantly decreased" during the visit.
