The IAEA reported that its team at the site heard explosions throughout the week, including several near the plant. However, no damage to the power plant itself was reported.
Last Saturday, Sept. 21, the NPP staff informed the IAEA team about a possible drone strike that occurred on Sept. 20, purportedly targeting a substation approximately 300 meters from the plant.
"This substation provides electricity to non-safety related facilities at the ZNPP, including a grid-water pumping station, a water management plant, and external warehouses," the statement said.
The day after the suspected attack, IAEA observers inspected the site and noted signs of impact on one of the two transformers at the substation. Possible drone debris was also found in the area.
The ZNPP, Ukraine’s largest nuclear facility, has been under illegal Russian occupation since March 2022.
