At the beginning of the Russian invasion of Ukraine, during the Battle of Enerhodar on 4 March 2022, Zaporizhzhia Nuclear Power Plant (ZNPP) , the largest nuclear power plant in Europe, was attacked and occupied by Russian forces. It was the first full-scale military attack and occupation of an operational nuclear power plant in history. It has become the center of an ongoing nuclear safety crisis, described by Ukraine as an act of nuclear terrorism by Russia.
