mdsolar writes in with news about a NRC rule on how long nuclear waste can be stored on-site after a reactor has shut down. The five-member board that oversees the Nuclear Regulatory Commission on Tuesday voted to end a two-year moratorium on issuing new power plant licenses. The moratorium was in response to a June 2012 decision issued by the U.S. Court of Appeals for the District of Columbia that ordered the NRC to consider the possibility that the federal government may never take possession of the nearly 70,000 metric tons of spent nuclear fuel stored at power plant sites scattered around the country. In addition to lifting the moratorium, the five-member board also approved guidance replacing the Waste Confidence Rule. "The previous Waste Confidence Rule determined that spent fuel could be safely stored on site for at least 60 years after a plant permanently ceased operations," said Neil Sheehan, spokesman for the NRC. In the new standard, Continued Storage of Spent Nuclear Fuel Rule, NRC staff members reassessed three timeframes for the storage of spent fuel — 60 years, 100 years and indefinitely.
