An opinion poll in April 2016 showed that about half of Swedes want to phase out nuclear power, 30 percent want its use continued, and 20 percent are undecided. Prior to the Fukushima Daiichi nuclear disaster in 2011, "a clear majority of Swedes" had been in favour of nuclear power. In June 2016, the opposition parties and the government reached an agreement on Swedish nuclear power. The agreement is to phase out the output tax on nuclear power, and allow ten new replacement reactors to be built at current nuclear plants.
