Update 170 – IAEA Director General Statement on Situation in Ukraine

Vienna, Austria

Ukraine’s Zaporizhzhya Nuclear Power Plant (ZNPP) lost the connection to its main external power line early this morning, forcing it to rely on recently restored back-up power supplies for the electricity it needs for essential nuclear safety and security functions, Director General Rafael Mariano Grossi of the International Atomic Energy Agency (IAEA) said.

The ZNPP’s sole remaining 750 kilovolt (kV) power line – out of four available before the conflict – was disconnected at 01:21am local time today. It was not immediately known what had prompted the power cut or how long it would last.

Europe’s largest nuclear power plant has been experiencing major off-site power problems since the conflict began in early 2022, exacerbating the nuclear safety and security risks facing the site currently located on the frontline.

The disconnection of the 750 kV power line meant the ZNPP had to switch to its only available 330 kV back-up power line for off-site electricity that is required, for example, to pump cooling water for the plant. This 330 kV line was only reconnected to the plant on 1 July after being damaged four months ago.

“This time the plant avoided a complete loss of all external power – which has happened seven times previously during the conflict – but the latest power line cut again demonstrates the precarious nuclear safety and security situation at the plant,” Director General Grossi said.
