datory information collections in 10 CFR Parts 50 and 52 that are subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et. seq.).

DG-1373, Page 5 B. DISCUSSION Reason for Issuance This guide describes an acceptable approach for applicants and licensees subject to 10 CFR Parts 50 or 52 to demonstrate that NRC regulatory requirements are met for subcriticality of fuel assemblies stored in fresh fuel vaults and spent fuel pools at LWR power plants. This guidance provides clarity and consistency regarding the necessary scope of efforts for applicants and licensees to demonstrate compliance with the requirements of 10 CFR 50.68(b) for performing criticality analyses of fuel storage at LWR power plants and maintain exemptions to 10 CFR 70.24. Specifically, this RG endorses, with clarifications and exceptions, the NEI guidance document NEI 12-16, Revision 4. This RG updates and supersedes DSS-ISG-2010-01, which will be withdrawn upon issuance of this RG. Licensees that already use DSS-ISG-2010-01 to demonstrate compliance with NRC requirements may continue using that guidance as long as they do not change their licensing bases relative
