NUCLEAR REGULATORY COMMISSION

[NRC-2024-0183]


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.

    Dated: March 10, 2025.

    For the Nuclear Regulatory Commission.

Acting Director, Office of Nuclear Reactor Regulation.
