This is stated in the IAEA statement.

It is noted that a new group of agency employees arrived at the station this week. 

“This is the fourth group of the agency’s experts at Europe’s largest nuclear power plant since the creation of the IAEA mission to assist the Zaporozhye NPP on September 1,” the IAEA said.

Earlier, the head of the International Atomic Energy Agency, Rafael Grossi, said that the situation around the Zaporozhye nuclear power plant is still fragile and potentially dangerous.
