ordance with 10 CFR 50.71(e),” issued in September 1999, provides guidance for periodically updating final safety analysis reports (FSARs) in accordance with the requirements of Title 10 of the Code of Federal Regulations (10 CFR) 50.71(e). RG 1.181 endorses Nuclear Energy Institute (NEI) 98-03, Revision 1, dated June 1999, by providing a regulatory position that states that it provides methods that are acceptable to the NRC staff for complying with the provisions of 10 CFR 50.71(e).

The referenced report, “San Onofre Steam Generator Tube Degradation Lessons Learned Report,” (ADAMS Accession No. ML15015A419), issued on March 6, 2015, did not provide any recommendations for revision to RG 1.181. The NEI submitted a proposed revision to NEI 98-03 (Draft Revision 2, ADAMS Accession No. ML15089A320) on March 24, 2015 with the intent to add new guidance related to FSARs for licensing activities under 10 CFR Part 52, , “Licenses, Certifications, and Approvals for Nuclear Power Plants.” NRC staff provided preliminary comments on February 28, 2017 (ADAMS Accession No. ML16222A424) that referenced needed updates, clarifications, corrections, and additions to the previously endorsed guidance of NEI 98-03, Revision 1. The NRC staff comments included a discussion of key issues related to the treatment of historical information and updating of aging management and time limited aging analyses information and included a redline markup of NEI 98-03, Draft Revision 2 that requested specific changes in several general areas including: •
