IAEA will report to UN on Zaporizhzhia nuclear power plant mission on Tuesday, September 6

He stated this at a press conference at the Vienna airport after returning from Ukraine.

"We are now trying to give an in-depth assessment of the situation. And I plan to do a preliminary report next week, once we have the full picture," Grossi said when asked when he would report on the trip to the nuclear power plant for the IAEA's governing board.

He added that on Tuesday he will also report to the UN Security Council "about our conclusions and what is happening."

According to the director general of the IAEA, a "unique and unprecedented" situation has developed at the Zaporizhzhya NPP, where "there is a Ukrainian nuclear power plant that is controlled by the Russian occupation forces."

When asked if the IAEA learned anything new as a result of the visit, Grossi replied: "We knew a lot, but of course our job is to inspect. And the difference between being there and not being there is like the difference between day and night. So we had a lot  information about various things, but now I and my technical experts are able to assess their seriousness."

According to Grossi, the IAEA now knows "much more" and continues to receive more information, given that some experts remained at the Zaporizhzhia NPP.

He also noted that the issue of returning the ZNPP to Ukrainian control is "outside the capabilities" of the IAEA, which deals with inspection and technical issues.

At the same time, Grossi did not mention the need to create a demilitarized zone around the ZNPP.  When asked by journalists about Ukraine's criticism of the IAEA for the lack of such appeals, he stated that every state "has the right to expect that the Agency will say what it would like."
