Securing America's Nuclear Waste Act This bill addresses storage of spent nuclear fuel and high-level radioactive waste in the United States. Specifically, the bill requires the Government Accountability Office to report on the risks to current storage locations for spent nuclear fuel, including spent nuclear fuel from civilian nuclear power reactors, and high-level radioactive waste, including risks that are related to global weather patterns and geography; the Office of Management and Budget to report on the economic benefits of consolidated interim storage of spent nuclear fuel and high-level radioactive waste, including economic benefits associated with job growth and redeveloping sites of decommissioned civilian nuclear power reactors; and the Department of Energy to study and report on an auction process or other system for selecting and entering into contracts with nonfederal entities for consolidated interim storage facilities that are located at a site without an operating nuclear reactor, and for which such entities will hold a license issued by the Nuclear Regulatory Commission.
