The Russians have not yet granted the International Atomic Energy Agency (IAEA) experts present at the Russian-occupied Zaporizhzhia nuclear power plant (ZNPP) access to all nuclear reactor halls of the power plant, IAEA Director General Rafael Mariano Grossi said.
Russian troops occupied the biggest nuclear power plant in Europe, Zaporizhzhia NPP, in the Zaporizhzhia Oblast (southeastern Ukraine) on 4 March 2022. Russia restricts international observers’ access to the nuclear power plant.
Generally, five nuclear reactors of the Zaporizhzhia NPP have been in cold shutdown, with one kept in hot shutdown, which the IAEA reported was necessary to produce steam for nuclear safety purposes, including the processing of liquid radioactive waste in storage tanks.
