Several countries have enacted laws to cease construction on new nuclear power stations. Several European countries have debated nuclear phase-outs and others have completely shut down some reactors. Three nuclear accidents have influenced the slowdown of nuclear power: the 1979 Three Mile Island accident in the United States, the 1986 Chernobyl disaster in the USSR, and the 2011 Fukushima nuclear disaster in Japan. Following the March 2011 Fukushima nuclear disaster, Germany has permanently shut down eight of its 17 reactors and pledged to close the rest by the end of 2022. Italy voted overwhelmingly to keep their country non-nuclear. Switzerland and Spain have banned the construction of new reactors. Japan's prime minister has called for a dramatic reduction in Japan's reliance on nuclear power. Taiwan's president did the same. Shinzō Abe, prime minister of Japan since December 2012, announced a plan to restart some of the 54 Japanese nuclear power plants and to continue some nuclear reactors under construction.
