The Zaporizhia nuclear power plant near the annexed city of Energodar was disconnected from external power supply on the afternoon of November 23. This was announced by the head of the International Atomic Energy Agency (IAEA) Rafael Grossi.
The station switched to power from emergency diesel generators to provide the power needed to cool the reactor and "other important nuclear safety and security functions," Grossi said, citing IAEA staff who work at the Zaporizhzhya NPP.
According to IAEA officials, the station lost access to external power supply at 15:30 local time - after reports of a massive missile attack on Ukraine's energy infrastructure.
The Ukrainian "Energoatom" and the Russian-appointed authorities of the annexed Energodar also said that the Zaporizhzhya NPP was de-energized.
During a missile attack on Ukrainian energy facilities on the afternoon of November 23, as Energoatom said, due to a decrease in the frequency in the country's energy system, emergency protection worked at the Rivne, South-Ukrainian and Khmelnytsky nuclear power plants, due to which all power units of the nuclear power plant automatically turned off . The stations continued to operate in the design mode without generating electricity for the power grid.
The need for a reliable power supply from the grid for all nuclear facilities is one of the essential pillars of ensuring nuclear safety and protection during armed conflict.
