This legislation aims to significantly alter the licensing authority of the Nuclear Regulatory Commission (NRC) regarding nuclear waste storage. Congress finds that the NRC lacks express statutory authority to issue licenses for private, away-from-reactor storage sites, commonly known as consolidated interim storage facilities , and notes ongoing legal challenges to the NRC's authority. It emphasizes public safety concerns related to the transportation and storage of spent nuclear fuel and high-level radioactive waste. The bill explicitly prohibits the NRC from issuing new licenses for the interim storage of spent nuclear fuel or high-level radioactive waste at any facility other than the civilian nuclear power reactor where the waste was generated or a federally owned interim storage facility. Additionally, it forbids licenses for long-term storage or permanent disposal at any facility other than a federally owned repository. A critical provision of this Act is the immediate nullification of any existing licenses that fall under these newly prohibited categories, effectively revoking current private interim storage permits.
