UN nuclear chief says security still fragile at Ukraine's Zaporizhzhia NPP

Security at Ukraine’s Zaporizhzhia Nuclear Power Plant remains fragile amid worrying recent staff cuts enacted by Russian authorities occupying the facility, which is one of the 10 biggest atomic power plants in the world, the United Nations nuclear watchdog chief said on February 6.

International Atomic Energy Agency chief Rafael Grossi, who is in Kyiv, told The Associated Press that his upcoming visit to the plant as the war approaches its two-year milestone will aim to assess the impact of recent personnel reductions after Russia denied access to employees of Ukraine’s Energoatom.

“This huge facility used to have around 12,000 staff. Now, this has been reduced to between 2,000 and 3,000, which is quite a steep reduction in the number of people working there,” Grossi said. “To man, to operate these very sophisticated big installations you need a certain number of people performing different specific functions.”

“So far the situation is stable, but it is a very, very delicate equilibrium,” he said. “So this is why I need to see for myself what is the situation, what are the prospects in terms of staffing, medium-term and long-term as well.”

The IAEA has repeatedly expressed alarm about the Zaporizhzhia facility amid fears of a potential nuclear catastrophe. The plant has repeatedly been caught in the crossfire since Russia launched its full-scale invasion of Ukraine on Feb. 24, 2022, and seized the facility shortly after.

The plant’s six reactors have been shut down for months, but it still needs power and qualified staff to operate crucial cooling systems and other safety features.

Rossi said he would also check the stability of the facility’s cooling function in the wake of the Kakhovka Dam collapse over the summer, and the presence of mines in and around the plant.
