Inspectors denied access to parts of Ukraine nuclear plant: IAEA

The head of the UN nuclear power watchdog said on Wednesday his inspectors had been denied access to parts of Ukraine’s Russian-occupied Zaporizhzhia nuclear power station and had yet to receive 2024 maintenance plans for the facility.

The plant was seized by Russia in the days following Moscow’s 2022 invasion of Ukraine. Each side has accused the other of shelling around the station, Europe’s largest, though its six reactors now produce no electricity.

Rafael Grossi, director-general of the International Atomic Energy Agency (IAEA), said inspectors at the plant had for two weeks had no access to the main halls of reactors one, two and six.

“This is the first time that IAEA experts have not been granted access to a reactor hall of a unit that was in cold shutdown,” Grossi said in a statement on the IAEA website.

“This is where the reactor core and spent fuel are located. The team will continue to request this access.”

Inspectors had also been restricted in their access to turbine halls at the plant which is situated in southeastern Ukraine, he said.

Petro Kotin, head of Ukraine’s state nuclear power company Energoatom, said Russia might be attempting to hide the true state of affairs at the plant.

The country’s nuclear security could only be restored with the de-occupation of the plant and territories nearby, he added in a message on the Telegram app.

Grossi said the plant’s operators had taken action to ensure back-up electricity supplies to the facility for when its main external power line is lost, which he described as a “repeated” occurrence.

Losing its main power source has prompted concern as the plant needs power to cool its reactors, even when shut down.
