WASHINGTON, April 22. /TASS/. Serious incidents at the Zaporozhye Nuclear Power Plant (ZNPP) cannot be ruled out completely until a ceasefire is established, Director General of the International Atomic Energy Agency (IAEA) Rafael Grossi said. "And we would never say ‘mission accomplished’ because until there is a ceasefire, or until this, let alone peace, but until we see much less military activity in the vicinity of the plant, the possibility of having something serious cannot be excluded," he said at a seminar organized by the Council on Foreign Relations, a US independent think tank, in Washington. Located in the city of Energodar, the Zaporozhye NPP is Europe’s largest nuclear power plant and has six power units with an aggregate capacity of 6 GW, which are now in a state of cold shutdown and are not generating energy. Russian forces took control of the facility in February 2022. Since then, Ukrainian troops have been periodically shelling both the city and the plant’s territory. IAEA experts have been permanently present at the facility since September 2022, rotating regularly.
