he 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 the technical specifications for NRC approval. As a result of its review of these submittals, the NRC staff has identified common areas of decommissioning 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. Background After a licensee permanently shuts down a power reactor facility and the facility enters decommissioning, there is a transition period to reconfigure the licensing basis and operational approach to reflect the differences between an operating power reactor facility and a power reactor facility in decommissioning.

These regulations establish a timeframe for the completion of decommissioning, determine which types of activities require prior approval before being implemented, govern the release criteria that the site must meet to qualify for license termination, outline the appropriate use of decommissioning funds, and set up the enveloping environmental considerations for decommissioning, among other items. The NRC initially updated the termination of license regulations in 1996 (Volume 61 of the Federal Register (FR), page 39278 (61 FR 39278); July 29, 1996) (Ref. 13) and made additional changes to the decommissioning regulations in 1997 (62 FR 39091) (Ref. 14), 2003 (68 FR 19727) (Ref. 15), and 2014 (79 FR 66603) (Ref. 16).
