But in 2010, the Obama administration scrapped the controversial plan. In 2002, George W Bush approved Yucca Mountain, a site about 100 miles from Las Vegas, as a permanent underground nuclear waste repository. Under the US Nuclear Waste Policy Act of 1982, the federal government was to move waste into a centralized, remote federal facility starting in 1998. SCE tried to fix the problem but decided in 2013 to shut the plant down for good.Īctivists thought they had scored a victory when the reactor shut down – until they learned that the nuclear waste they had produced would remain on-site. A subsequent report from the NRC’s inspector general found federal inspectors had overlooked red flags in 2009, and that SCE had replaced its own steam generators without proper approval. But when a new steam generator began leaking a small amount of radioactivity in January 2012, just one year after it was replaced, it was SCE’s most serious problem yet. That waste is the byproduct of the San Onofre Nuclear Generating Station (Songs), three nuclear reactors primarily owned by the utility Southern California Edison (SCE).įederal regulators had already cited SCE for several safety issues, including leaking radioactive waste and falsified firewatch records. ![]() “It’s a combination of failures, really,” said Gregory Jaczko, who chaired the US Nuclear Regulatory Commission (NRC), the top federal enforcer, between 20, of the situation at San Onofre. The San Onofre reactors are among dozens across the United States phasing out, but experts say they best represent the uncertain future of nuclear energy.
