The International Atomic Energy Agency (IAEA) said on Sunday that Ukraine's energy infrastructures came under large-scale Russian attack, with several electrical substations powering the country's nuclear power plants being severely damaged.
Rafael Grossi, the IAEA Director General, said in the agency's latest update on the situation in Ukraine that operating nuclear power plants (NPPs) across the country had moved to reduce their electricity production as a "precautionary measure" on Sunday morning, following widespread military activities that reportedly targeted Ukraine's energy infrastructure.
According to a report citing information from Ukraine's national regulator, the NPPs -- Khmelnytskyy, Rivne and South Ukraine -- "were not directly impacted and did not shut down," but several electrical substations that support their operation "suffered further damage during the strikes."
"Only two of the country's nine operational reactors currently generate electricity at 100 percent capacity," the director general's statement said.
The statement also noted that IAEA teams visited seven substations across Ukraine in September and October to assess the damage after a spate of Russian attacks in August, and said teams will now consider whether it is necessary to make further visits following Sunday's military activities.
