II. Discussion

Draft NUREG-1482, Revision 4 is applicable, unless stated otherwise, to editions and addenda (up to and including the 2020 Edition) to the OM Code that are incorporated by reference in paragraph 50.55a of title 10 of the Code of Federal Regulations (10 CFR), “Codes and standards.” The NRC staff discusses in this report IST program topics such as the NRC process for the review of the OM Code, conditions on the use of the OM Code, interpretations of the OM Code, and development of IST programs for new reactors. In this report, the NRC staff provides guidance included in NUREG-1482, Revision 3 that has been updated to reflect IST lessons learned and operating experience since the report was previously issued.

Effective August 16, 2024, the NRC amended 10 CFR 50.55a in a final rule (89 FR 58039; July 17, 2024) to provide more flexibility for nuclear power plant licensees by expanding the code of record interval from 10 years (120 months) to two consecutive IST and inservice inspection (ISI) program intervals. This rulemaking also incorporated by reference revisions to three NRC regulatory guides to approve new, revised, and reaffirmed ASME Code Cases. Accordingly, draft NUREG-1482, Revision 4 includes the new terminology for the code of record interval rather than the previous 120-month interval when discussing IST and ISI programs and also includes a new Appendix C that summarizes the final rule and its conditions.
