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 

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.

NUCLEAR REGULATORY 

COMMISSION 

[NRC–2020–0160] 

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 

Federal Register / Vol. 86, No. 36 / Thursday, February 25, 2021 / Notices 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).

IV. Congressional Review Act 

These ISGs are rules as defined in the 

Congressional Review Act (5 U.S.C. 

801–808). However, the Office of 

Management and Budget has not found 

them to be major rules as defined in the 

Congressional Review Act.

ACTION: Notice of changes. 

SUMMARY: The Postal Service has 

updated the Postal Operation Manual 

(POM) to revise Standard 4C concerning 

apartment parcel locker ratios. 

DATES: Federal Register Publication: 

December 18, 2020 to January 19, 2021. 

FOR FURTHER INFORMATION CONTACT: 

Delivery.Growth@usps.gov, Valerie 

Barksdale, 202–268–2567. 

SUPPLEMENTARY INFORMATION: The Postal 

Service has revised Postal Operations 

Manual (POM) section 632.622a. These 

changes revise the parcel locker ratio in 

apartment community buildings from

This change is necessary to 

accommodate an increase in package 

volume. 

Although, the Postal Service had 

already made this change to the POM, 

a solicitation was published in the 

Federal Register on December 18, 2020 

seeking comments from the public 

concerning this change. The comment 

period ran from December 18. 2020 to 

January 19, 2021, and as of that later 

date, no comments were received. 

The Postal Service will continue to 

apply the POM provision at issue. You
