Edited sentence: According to a New Scientist report, spent fuel from the new reactors will be far more radioactive than existing waste.Although the Labour Government appeared to rule out new nuclear power stations as recently as 2003, it gradually shifted its position, with the backing of Tony Blair and Gordon Brown, who are both nuclear enthusiasts.In 1976, the UK Royal Commission on Environmental Pollution found that it would be "morally wrong to make a major commitment to nuclear power without first demonstrating a safe way of isolating radioactive waste".In January 2008 the UK government announced plans to build new nuclear power stations, and the anti-nuclear movement in the United Kingdom has voiced concerns.In May 2009, new safety concerns at Britain's largest atomic site, Sellafield, include a 14-month radioactive leak and the loss of two toxic containers.The Liberal Democrats, alone of the major parties, remain resolutely anti-nuclear.These events threaten to undermine confidence in the government's "nuclear renaissance".Yet the UK is about to embark on a programme to build at least 10 new reactors while still lacking a disposal site for waste from the past 50 years
