nuclear power phase-out is the discontinuation of usage of nuclear power for energy production . Often initiated because of concerns about nuclear power , phase-outs usually include shutting down nuclear power plants and looking towards fossil fuels and renewable energy . Three nuclear accidents have influenced the discontinuation of nuclear power : the 1979 Three Mile Island partial nuclear meltdown in the United States , the 1986 Chernobyl disaster in the USSR , and the 2011 Fukushima nuclear disaster in Japan . As of 2018 , Italy is the only country that operated nuclear reactors that has since phased out nuclear power completely
