Draft NUREG: Guidelines for Inservice Testing at Nuclear Power Plants: Inservice Testing of Pumps and Valves and Inservice Examination and Testing of Dynamic Restraints (Snubbers) at Nuclear Power Plants
AGENCY:
Nuclear Regulatory Commission.
ACTION:
Draft report; request for comment.
SUMMARY:
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft report entitled NUREG-1482, Revision 4, "Guidelines for Inservice Testing at Nuclear Power Plants: Inservice Testing of Pumps and Valves and Inservice Examination and Testing of Dynamic Restraints (Snubbers) at Nuclear Power Plants." This report provides a basic understanding of the regulatory basis for pump and valve inservice testing (IST) programs and dynamic restraint (snubbers) examination and testing programs at nuclear power plants. It also provides information regarding the NRC's involvement in the development of the American Society of Mechanical Engineers (ASME) "Operation and Maintenance of Nuclear Power Plants," Division 1, "OM Code: Section IST" (OM Code).
DATES:
Submit comments by April 14, 2025. Comments received after this date will be considered if it is practical to do so, but the Commission is able to ensure consideration only for comments received on or before this date.
ADDRESSES:
You may submit comments by any of the following methods; however, the NRC encourages electronic comment submission through the Federal rulemaking website:

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.
