Zaporizhzhia Nuclear Plant Plunged Into 16th Blackout of Year

Zaporizhzhia Nuclear Power Plant (ZNPP) in Ukraine endured its 16th blackout this year on November 8, compelling the facility to rely on emergency diesel generators, according to Ukrainian state nuclear energy operator Energoatom. The episode occurred at 2:36 a.m. local time when the final functional 330-kilovolt (kV) overhead line, "Ferrosplavna-1," was detached from Ukraine's unified power grid.

Energoatom stated that the station's reliance on backup generators poses grave risks, such as equipment malfunction, fuel depletion, or inadequate cooling, potentially triggering a radiation catastrophe. The operator warned that the recurring power losses directly stem from the Russian occupation of the ZNPP. Currently, all six reactor units at Europe's largest nuclear generating station remain in a cold shutdown status, necessitating a constant flow of cooling water to avert damage to fuel elements and spent fuel pools.

Ukrainian Military Intelligence reported that roughly 1,150 technicians manage the facility's safety systems under Russian occupation, stressing that protracted power outages strain local fuel reserves, with the plant consuming around 150 metric tons of diesel fuel daily during full grid disconnections. The "Ferrosplavna-1" line has suffered multiple interruptions this year, with three such outages recorded in August alone.

In June, engineers successfully reestablished the connection after an extended 65-hour blackout that left the station dependent on emergency generators for nearly three days. The facility's safety concerns have grown due to the dwindling water levels in the primary cooling pond. Ukrainian intelligence recorded the pond level falling from 12.9 meters in July to 12.6 meters in late August, falling short of the 15-meter mark essential for optimal operations.
