Since the outage, the largest nuclear power plant in Europe has been powered by backup diesel generators. The IAEA says safety has been maintained with reactors continuing to be effectively cooled.
Located near the city of Enerhodar along the Dnieper River, the nuclear plant is close to the front line.
Its six reactors, which produced about one-fifth of Ukraine’s electricity before the war, were shut down after Moscow took control.
However, the plant needs electricity to maintain its cooling and safety systems to prevent a disaster.
At the beginning of October, Moscow claimed that the situation was “under control” in Zaporizhzhia following concerns raised by Ukrainian President Volodymyr Zelenskyy.
Moscow and Kyiv have repeatedly accused each other of risking a nuclear disaster by attacking the site and have blamed each other for the latest power outage.
