Zaporizhzhia nuclear plant loses external power, runs on diesel generators

The Zaporizhzhia nuclear power plant lost its only remaining external power line early on Sunday, the 27th such loss during the conflict, the IAEA said, and the plant is running on emergency diesel generators with about two weeks of fuel for a limited number of them.

Why it matters: Europe's largest nuclear plant, occupied by Russia since 2022 with all six reactors shut down, still needs constant power for cooling and safety systems, and each loss of its grid connection leaves that safety margin resting on diesel stocks the IAEA says should be increased.

The International Atomic Energy Agency said the Zaporizhzhia nuclear power plant lost connection early on Sunday to its only remaining external power line, the 330 kV Ferrosplavnaya-1 line, the 27th time the plant has lost external power during the conflict, and that the causes of the outage are still unknown. The plant switched to emergency diesel generators to cool its reactors and provide other nuclear safety functions, and IAEA experts at the site were told the plant has enough fuel for a limited number of the generators for about two weeks. Director General Rafael Grossi stressed the importance of restoring the grid connection and of increasing the diesel fuel stocks on site.

The plant’s Russian-installed management said the line had been shut down by automatic protection because of damage, that backup diesel generators are supplying the equipment required for the station’s safe operation, and that radiation levels at the plant and in the surveillance zone are normal, Reuters reported. That is the management’s own account; what damaged the line has not been independently established.

All six of the plant’s reactors have been shut down since 2022, but their fuel still needs continuous cooling, which is why the external lines matter. The second line supplying the plant was cut in March, Sweden Herald reported, leaving Ferrosplavnaya-1 as the last working connection until Sunday.
