lization facilities, such as nuclear power reactors. The rulemaking, titled “Regulatory Improvements for Production and Utilization Facilities Transitioning to Decommissioning” (RIN No: 3150-AJ59; NRC Docket ID: NRC-2015-0070), amended 10 CFR 50.82, along with numerous other regulations, to provide for a more efficient process for transitioning to decommissioning, to reduce the need for exemptions from existing regulations and license amendment requests, and to address other decommissioning issues identified by the NRC staff that could streamline and improve the overall decommissioning process. Since the issuance of Revision 1 of this RG, several licensees have submitted PSDARs for the NRC’s review as well as license amendment requests with proposed changes to technical specifications for NRC approval. As a result of its review of these submittals, the NRC staff has identified common areas of decommissioning planning that frequently require clarification or that could be enhanced as part of the overall process, including the need for early communication, insufficient information in environmental reports, the need for early detection of spills, discussions involving the decommissioning strategy and timeline, plans for public involvement opportunities during decommissioning, discussions involving the plans for storage of spent fuel, and estimates of decommissioning costs. Scope of this Regulatory Guide This RG describes methods and procedures that are acceptable to the NRC staff for implementing the decommissioning regulations that relate to both the initial activities and major phases of the decommissioning process. It does not contain guidance on the license termination process. That process is addressed in RG 1.179, “Standard Format and Content of License Termination Plans for Nuclear Power Reactors.” This RG also addresses the irradiated fuel management plan (IFMP) (alternatively referred to as the spent fuel management plan) requirements described in 10
