"We are increasing the number of experts because of two main reasons. First, of course, this unexpected situation that we have after the destruction of the dam," Grossi said.
The second reason is an effort to implement the five principles that Grossi put forward last week to ensure nuclear safety and security at the ZNPP. The principles include:
a ban on shelling toward and from the site;
storing heavy weapons there.
"From the IAEA perspective, we have been trying to act as a bit of an intermediary sometimes to make the points understood between one [Ukrainian staff] and the other side [Russian management]. So far, we have been able to avoid major problems, but there have been tensions, and I think we have to deal with this. It's a reality and I think it wouldn't be correct for me to pretend that there are none," Grossi told Sputnik.
The Zaporozhye nuclear power plant, Europe's largest, uses water from the Kakhovka reservoir for cooling purposes. The Kakhovka reservoir in turn is created by the Kakhovka hydroelectric power plant dam, which was destroyed early Tuesday, triggering flooding in towns downstream and endangering the power plant.
The Russian Foreign Ministry has said Ukrainian armed forces attacked the dam, qualifying it as a terrorist act against civilian infrastructure launched as part of Ukraine's "so-called" counteroffensive. Kiev, in turn, blamed Moscow for the attack.
