Without Nuclear by a margin of 33.7% for and 66.3% opposed. The former ten-year moratorium on the construction of new nuclear power plants was the result of a federal popular initiative voted on in 1990 which had passed with 54.5% Yes vs. 45.5% No votes (see Nuclear power in Switzerland for details). In May 2011, due to the Fukushima accident in Japan, the Swiss government decided to abandon plans to build new nuclear reactors. The country's five existing reactors will be allowed to continue operating, but will not be replaced at the end of their life span. The last will go offline in 2034.
