According to the IAEA, South Ukraine and Khmelnytsky NPP lost access to one of the external power transmission lines, while Rivne NPP had to reduce the capacity of two reactors at the request of the system operator. All this is due to a massive night attack by the Russian Federation on Ukraine's energy infrastructure in the early hours of October 30. The Director General of the agency, Rafael Grossi, called the situation another reminder of the constant nuclear threat.
Consequences of the Russian Attack on Ukrainian NPPs on October 30
The IAEA reports that despite losing part of the power supply, NPPs continue to operate without incidents, but the risks remain high. According to Grossi, any strikes near critical infrastructure and nuclear facilities pose a real danger.
It is known that Rivne station reduced the load of two of its four units. The other facilities are operating normally, and backup power sources are engaged.

Why This Happened
On the night of October 30, Russia carried out another massive attack on Ukraine using drones and missiles. According to the Air Force, air defense systems shot down or suppressed 623 of 705 targets, including 592 strike drones and 29 cruise missiles.
However, at least 16 missiles and 63 UAVs hit targets, while another 19 fell as debris in various regions. Western regions were also hit, particularly Vinnytsia, Prykarpattia, and Lviv. In many regions, emergency power outages were temporarily implemented.
IAEA emphasized that adherence to international standards and seven key principles of nuclear safety is critical during wartime. The agency continues to monitor the situation at Ukrainian NPPs.
