NUCLEAR REGULATORY COMMISSION
[NRC-2024-0183]
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: Final report; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing 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.''
NUREG-1482, Revision 4 provides a basic understanding of the regulatory
basis for pump and valve inservice testing (IST) programs and dynamic
restraint (snubbers) examination and testing programs. This NUREG 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: This document was published in the Federal Register on October

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC published a notice in the Federal Register on March 14,
2025 (90 FR 12184) requesting public comment on draft NUREG-1482,
Revision 4. The public comment period closed on April 14, 2025. The NRC
received 46 public comments. The public comments and the NRC staff's
responses are presented in a comment resolution matrix available in
ADAMS under Accession No. ML25262A190. The staff considered the public
comments received on the draft document in preparing final NUREG-1482,
Revision 4.
NUREG-1482, Revision 4 is applicable, unless stated otherwise, to
editions and addenda (up to and including the 2022 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, 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. In addition, in response to a public comment,
NUREG-1482, Revision 4 has been revised throughout to reference the
2022 Edition of the OM Code (the latest edition incorporated by
reference in 10 CFR 50.55a) instead of the 2020 Edition. In accordance
with 10 CFR 2.804(e)(2), the NRC staff has determined that a post-
promulgation comment period would serve no public interest given the
nature of the updates from the 2020 to the 2022 Edition of the OM Code.
II. Congressional Review Act
This NUREG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). The Office of Management and Budget has found that it
does not meet the criteria at 5 U.S.C. 804(2).
III. Executive Order (E.O.) 12866
The Office of Information and Regulatory Affairs determined that
this NUREG is not a significant regulatory action under E.O. 12866.
Dated: September 29, 2025.
For the Nuclear Regulatory Commission.

Acting Director, Office of Nuclear Reactor Regulation.
