The IAEA team at the ZNPP observed light smoke rising from the direction of the ZTPP and heard sounds of military activity. ZTPP staff are sheltering as a result of the attack.

The incident has raised serious concern about the ZNPP’s sole remaining off-site power line, which in recent weeks has been disconnected several times, leaving the plant reliant on emergency diesel generators to cool its six reactors and prevent a nuclear accident.

For now, the power line remains connected but the incident comes amid repeated threats to the plant’s external power supply.

In a separate incident on June 3 the ZNPP lost off-site power for approximately 20 minutes after a drone strike on the Nikopolska substation across the Dnipro River.

That marked the 17th such temporary loss during the conflict. Emergency diesel generators supplied power until the line was restored shortly before midnight.
