Revision to Regulatory Guides (RGs)

The NRC issued a revision to RG 1.185, “Standard Format and Content for Postshutdown Decommissioning Activities Report.” The guide describes a method that the NRC staff considers acceptable for use in complying with the Commission’s requirements regarding the submission of a post-shutdown decommissioning activities report (PSDAR). This revision updates RG 1.185 to reflect lessons learned since its original issuance in 2000. It identifies the type of information that the PSDAR must contain and establishes a standard format for the PSDAR that the NRC staff considers acceptable.

The NRC also issued a revision to RG 5.29, ‘‘Special Nuclear Material Control and Accounting Systems for Nuclear Power Plants.’’ Revision 2 of RG 5.29 describes a method that the NRC staff considers acceptable to implement special nuclear material control and accounting system requirements for nuclear power plants.This guide applies to all nuclear power plants.
