FOR FURTHER INFORMATION CONTACT: Michael Eudy, Office of Nuclear Regulatory Research, telephone: 301– 415–1304, email: Michael.Eudy@nrc.gov and Marieliz Johnson, Office of Nuclear Reactor Regulation, telephone: 301– 415–5861, email: Marieliz.Johnson@ nrc.gov. Both are staff of the U.S. Nuclear Regulatory Commission, Washington, DC 20555–0001. SUPPLEMENTARY INFORMATION: I. Discussion The NRC is issuing a new guide in the NRC’s ‘‘Regulatory Guide’’ series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the agency’s regulations, techniques that the NRC staff uses in evaluating specific issues or postulated events, and data that the NRC staff needs in its review of applications for permits and licenses. II. Additional Information RG 1.237 was issued with a temporary identification of draft regulatory guide (DG)–1321. The NRC published a notice of the availability of DG–1321 in the Federal Register on May 5, 2020 (85 FR 26725) for a 60-day public comment period. The public comment period closed on July 6, 2020. Public comments on DG–1321 and the staff responses to the public comments are available in ADAMS under Accession No. ML20349A336. III. Congressional Review Act This RG is a rule as defined in the Congressional Review Act (5 U.S.C. 801–808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act. IV. Backfitting, Forward Fitting, and Issue Finality This RG provides guidance on implementation of a process for making changes to the design of structures, systems, and components of a facility being constructed under a combined license. Issuance of this RG, would not constitute backfitting as defined in section 50.109 of title 10 of the Code of VerDate Sep<11>2014 17:04 Feb 24, 2021 Jkt 253001 Federal Regulations (10 CFR), ‘‘Backfitting,’’ and as described in NRC Management Directive 8.4, ‘‘Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests’’; affect issue finality of any approval issued under 10 CFR part 52, ‘‘Licenses, Certificates, and Approvals for Nuclear Power Plants’’; or constitute forward fitting as defined in MD 8.4, because, as explained in this RG, licensees are not required to comply with the positions set forth in this RG. If, in the future, the NRC were to impose a position in this RG in a manner that would constitute backfitting or forward fitting or affect the issue finality for a part 52 approval, then the NRC would address the backfitting provision in 10 CFR 50.109, the forward fitting provision of MD 8.4, or the applicable issue finality provision in part 52, respectively. Dated: February 19, 2021. For the Nuclear Regulatory Commission. Meraj Rahimi, Chief, Regulatory Guidance and Generic Issues Branch, Division of Engineering, Office of Nuclear Regulatory Research.

No other comments were submitted. The NRC staff considered those comments in developing the final versions of the ISGs. The staff’s responses to the comments are provided in each of the final ISGs in appendices titled ‘‘Disposition of Public Comments.’’ These ISGs update NUREG–2191, ‘‘Generic Aging Lessons Learned for Subsequent License Renewal (GALL– SLR) Report,’’ and NUREG–2192, ‘‘Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants.’’ NUREG–2191 and NUREG–2192 were published in July 2017, and a full review and revision to these documents is not scheduled to be performed for several years. The staff has reviewed the first three subsequent license renewal applications (SLRAs) that were based on the previously noted guidance documents. During these reviews, the staff and applicants identified improvements to the guidance that would assist in preparing and reviewing future SLRAs more effectively and efficiently. These ISGs provide interim updates to NUREG–2191 and NUREG– 2192 to implement these improvements. These ISGs are not intended for standalone use. They provide revisions to NUREG–2191 and NUREG–2192 sections and tables that supersede the content in the NUREGs and are intended to be used within the context of the NUREGs. The revisions captured in these ISGs include: • Updates to recommended aging management programs; • changes to aging management review items in NUREG–2191 tables and corresponding summary tables in NUREG–2192; • new aging management review items in NUREG–2191 tables and corresponding summary tables in NUREG–2192; • changes to ‘‘further evaluation’’ guidance sections in NUREG–2192; • updates to references listed in affected NUREG–2191 sections; and • editorial corrections to relevant sections.

Changes to Subsequent License Renewal Guidance Documents

AGENCY: Nuclear Regulatory Commission.

ACTION: Interim staff guidance; issuance.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing three 
Interim Staff Guidance (ISG) documents that update aging management 
criteria for mechanical, structural, and electrical structures and 
components in the NRC's subsequent license renewal (SLR) guidance 
documents. Specifically, the ISGs revise guidance contained in NUREG-
2191, ``Generic Aging Lessons Learned for Subsequent License Renewal 
(GALL-SLR) Report,'' and NUREG-2192, ``Standard Review Plan for Review 
of Subsequent License Renewal Applications for Nuclear Power Plants.'' 
These ISGs are intended to facilitate preparation of SLR applications 
by clarifying existing guidance for aging management and adding new 
guidance, which also will facilitate the NRC staff's review of SLR 
applications.

DATES: This guidance is effective on March 29, 2021.

SUPPLEMENTARY INFORMATION:

I. Background

    On July 2, 2020 (85 FR 39938) and August 3, 2020, (85 FR 46735), 
the staff requested public comments on the following draft ISGs:
     Draft SLR-ISG-MECHANICAL-2020-XX; Updated Aging Management 
Criteria for Mechanical Portions of Subsequent License Renewal Guidance
     Draft SLR-ISG-STRUCTURES-2020-XX; Updated Aging Management 
Criteria for Structures Portions of Subsequent License Renewal Guidance
     Draft SLR-ISG-ELECTRICAL-2020-XX; Updated Aging Management 
Criteria for Electrical Portions of Subsequent License Renewal Guidance

[[Page 11565]]

     Errata for Draft SLR-ISG-MECHANICAL-2020-XX; Updated Aging 
Management Criteria for Mechanical Portions of Subsequent License 
Renewal Guidance

    The NRC received comments from the Nuclear Energy Institute by 
letter dated August 10, 2020 (ADAMS Accession No. ML20224A465). No 
other comments were submitted. The NRC staff considered those comments 
in developing the final versions of the ISGs. The staff's responses to 
the comments are provided in each of the final ISGs in appendices 
titled ``Disposition of Public Comments.''
    These ISGs update NUREG-2191, ``Generic Aging Lessons Learned for 
Subsequent License Renewal (GALL-SLR) Report,'' and NUREG-2192, 
``Standard Review Plan for Review of Subsequent License Renewal 
Applications for Nuclear Power Plants.'' NUREG-2191 and NUREG-2192 were 
published in July 2017, and a full review and revision to these 
documents is not scheduled to be performed for several years. The staff 
has reviewed the first three subsequent license renewal applications 
(SLRAs) that were based on the previously noted guidance documents. 
During these reviews, the staff and applicants identified improvements 
to the guidance that would assist in preparing and reviewing future 
SLRAs more effectively and efficiently. These ISGs provide interim 
updates to NUREG-2191 and NUREG-2192 to implement these improvements.
    These ISGs are not intended for standalone use. They provide 
revisions to NUREG-2191 and NUREG-2192 sections and tables that 
supersede the content in the NUREGs and are intended to be used within 
the context of the NUREGs. The revisions captured in these ISGs 
include:
     Updates to recommended aging management programs;
     changes to aging management review items in NUREG-2191 
tables and corresponding summary tables in NUREG-2192;
     new aging management review items in NUREG-2191 tables and 
corresponding summary tables in NUREG-2192;
     changes to ``further evaluation'' guidance sections in 
NUREG-2192;
     updates to references listed in affected NUREG-2191 
sections; and
     editorial corrections to relevant sections.

III. Backfitting, Forward Fitting, and Issue Finality

    These ISGs intend to revise guidance for the NRC staff reviewing 
SLRAs and for prospective applicants in preparing SLRAs. Issuance of 
these ISGs does not constitute a backfit as defined in section 
50.109(a)(1) of title 10 of the Code of Federal Regulations (10 CFR) 
and is not otherwise inconsistent with the issue finality provisions in 
10 CFR part 52. As discussed in the ``Backfitting'' sections of the 
final ISGs, the ISG positions do not constitute backfitting inasmuch as 
the ISGs are guidance directed to the NRC staff with respect to its 
regulatory responsibilities and to applicants who choose to follow the 
guidance. Applicants and potential applicants are not, with certain 
exceptions, the subject of either the backfit rule or any issue 
finality provisions under 10 CFR part 52. The NRC staff has no 
intention to impose the ISG positions on existing nuclear power plant 
licensees either now or in the future (absent a voluntary request for a 
change from the licensee).

[[Page 11566]]

IV. Congressional Review Act
