His concern for him Zaporizhia nuclear power plant of Ukraine, its head expressed International Atomic Energy Agency (IAEA), Rafael Grossi, citing delays in personnel changes, increased security presence on site and clashes.

“The sound of artillery near Ukraine’s Zaporizhia Nuclear Power Plant (ZNPP) and the temporary loss of the only remaining backup power line again underscored the persistent nuclear security risks during the military conflict in the country,” Grossi said in a statement.

The IAEA said its team members who are at the plant they heard about 20 “explosions” on Monday afternoon, noting that it was “apparently close to the factory.”

He also reported an increased security presence at the site in recent weeks.

“This is a worrying trend that shows the urgency and importance of establishing a nuclear safety and protection zone at the Zaporizhia nuclear power plant,” Grossi pointed out.

He also raised concerns about continued delays in the rotation of IAEA experts, saying the current team should have been replaced three weeks ago and that he hopes the rotation can finally take place later this week.

The UN nuclear agency also confirmed that the plant’s backup power line was restored on Sunday afternoon after it lost power twice on Saturday morning.
