NUCLEAR REGULATORY COMMISSION

[NRC-2023-0096]


NUREG: Issuance of Revised Subsequent License Renewal Guidance 
Documents

AGENCY: Nuclear Regulatory Commission.

ACTION: Final report; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing 
revised Subsequent License Renewal (SLR) Guidance Documents; which 
consists of NUREG-2191, ``Generic Aging Lessons Learned for Subsequent 
License Renewal (GALL-SLR) Report, Final Report,'' Revision 1, Volumes 
1 and 2; NUREG-2192, ``Standard Review Plan for Review of Subsequent 
License Renewal Applications for Nuclear Power Plants (SRP-SLR), Final 
Report,'' Revision 1; and NUREG-2221, ``Technical Bases for Changes in 
the Subsequent License Renewal Guidance Documents, NUREG-2191, Revision 
1, and NUREG-2192, Revision 1 (Technical Bases Document),'' Supplement 
1. The GALL-SLR Report, Revision 1, and the SRP-SLR, Revision 1, 
provide revised guidance for nuclear power reactor licensees to the 
methods acceptable for the NRC staff to grant a subsequent license 
renewal in accordance with the license renewal regulations. The 
Technical Bases Document, Supplement 1, provides the associated 
technical bases of changes for the revisions.

DATES: This document was published in the Federal Register on July 17, 
2025.

SUPPLEMENTARY INFORMATION:

I. Discussion

    Section 54.29 of title 10 of the Code of Federal Regulations (10 
CFR) establishes the standards for issuance of a renewed license. For 
nuclear power plants that have received a renewed license, the 
regulations in 10 CFR 54.31(d) state that ``[a] renewed license may be 
subsequently renewed in accordance with all applicable requirements.'' 
The GALL-SLR Report was originally issued in 2017 to provide guidance 
for subsequent license renewals. The GALL-SLR Report lists generic 
aging management reviews of systems, structures, and components (SSCs) 
that may be in the scope of subsequent license renewal applications 
(SLRAs) and identifies aging management programs (AMPs) that are 
determined to be acceptable for managing the effects of aging on SSCs 
in the scope of license renewal, as required by 10 CFR part 54, 
``Requirements for Renewal of Operating Licenses for Nuclear Power 
Plants.'' If an applicant credits an AMP described in the GALL-SLR 
Report in the SLRA, the applicant should ensure that the conditions and 
operating experience (OE) at the plant are bound by the conditions and 
OE for which the GALL-SLR Report program was evaluated. If these 
bounding conditions are not met, the applicant should address any 
additional aging effects and augment the AMPs for subsequent license 
renewal.
    The SRP-SLR is a companion document, and intended to be used with 
the GALL-SLR Report. If an SLRA references the approach described in 
the GALL-SLR Report as the approach used for managing the aging 
effect(s), the NRC staff will use the GALL-SLR Report as a basis for 
the SLRA assessment, consistent with guidance specified in the SRP-SLR. 
The principal purposes of the SRP-SLR are to ensure the quality and 
uniformity of the NRC staff review and to present a well-defined base 
from which to evaluate applicant programs and activities for the 
subsequent period of extended operation. The SRP-SLR is also intended 
to make regulatory information widely available to enhance 
communication with interested members of the public and the nuclear 
power industry and to improve their understanding of the NRC staff 
review process.
    After the initial issuance of the GALL-SLR Report, Revision 0, and 
SRP-SLR, Revision 0, in 2017 (82 FR 32588), several documents referred 
to as Subsequent License Renewal Interim Staff Guidance (SLR-ISGs) were 
created to reflect new or updated industry guidance, codes, or 
standards; relevant plant operating experience; incorporation of 
lessons learned from completed SLR application reviews; development of 
new aging management programs or aging management review items; and 
identification of required corrections and clarifications to the 
guidance. GALL-SLR Report, Revision 1, and SRP-SLR, Revision 1, 
incorporate the issued SLR-ISGs, as well as additional updates 
identified subsequent to issuance of the SLR-ISGs.
    The NRC published a notice in the Federal Register on July 11, 2023 
(88 FR 44160) requesting public comments on draft SLR Guidance 
Documents. The public comment period was extended on September 7, 2023 
(88 FR 61628) and closed on October 11, 2023. The NRC received 203 
public comments. The public comments and the NRC staff's responses 
dispositioning these comments are presented in GALL-SLR Report, Volume 
2, Revision 1, Appendix C, and includes a comment resolution matrix. 
The NRC's resolution of these comments are incorporated into the final 
GALL-SLR Report, Revision 1 and the SRP-SLR, Revision 1, with 
associated technical bases of changes provided in the Technical Bases 
Document, Supplement 1.

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.
