Download as PDF 5267 Federal Register / Vol. 86, No. 11 / Tuesday, January 19, 2021 / Notices Appendix H, ‘‘Disposition of Public Comments,’’ of the final ISG. This ISG updates 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 above 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. This ISG provides an interim update to NUREG– 2191 and NUREG–2192 to implement these improvements. This ISG is not intended for standalone use. It provides revisions to NUREG–2191 and NUREG–2192 sections and tables that supersede the content in the NUREGs and is intended to be used within the context of the NUREGs. The revisions captured in this ISG include: • Updates to GALL–SLR Report aging management program XI.M16A, ‘‘PWR Vessel Internals’’; • 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 NUREG–2192 ‘‘further evaluation’’ guidance sections; • updates to references listed in affected NUREG–2191 sections; and • editorial corrections to relevant sections.

Backfit Discussion This ISG intends to revise guidance for the NRC staff reviewing SLRAs and for prospective applicants in preparing SLRAs. Issuance of this ISG 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’’ section of the final ISG, the ISG positions do not constitute backfitting inasmuch as the ISG is 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.

II. Additional Information

    The NRC is issuing for public comment a draft regulatory guide in 
the NRC's ``Regulatory Guide'' series. This series was developed to 
describe methods that are acceptable to the NRC staff for implementing 
specific parts of the NRC's regulations, to explain techniques that the 
staff uses in evaluating specific issues or postulated events, and to 
describe information that the staff needs in its review of applications 
for permits and licenses.
    This DG titled, ``Application and Testing of Safety-Related Diesel 
Generators in Nuclear Power Plants,'' is identified by its temporary 
task number, DG-1303. The draft guide is proposed revision 5 of RG 1.9 
of the same name (ADAMS Accession No. ML14281A071). This DG provides 
updated guidance for actions and information that is needed for 
licensees, applicants, and combined operating license (COL) holders to 
meet the NRC regulations for safety-related standby AC power supplies 
intended for use as onsite emergency power sources in nuclear power 
plants. Information provided in this DG may be used by NRC staff, 
applicants, COLs holders, and licensees. This guidance helps ensure 
that the emergency standby AC power supplies are qualified, have 
sufficient capacity, and have the necessary reliability and 
availability for design-basis events.
    The staff is also issuing for public comment a draft regulatory 
analysis (ADAMS Accession No. ML14297A097). The staff develops a 
regulatory analysis to assess the value of issuing or revising a 
regulatory guide as well as alternative courses of action.

III. Backfitting, Forward Fitting, and Issue Finality

    DG-1303, if finalized, would revise RG 1.9, revision 4, which 
describes methods acceptable to the NRC staff for complying with the 
NRC's regulations for safety-related standby AC power supplies intended 
for use as onsite emergency power sources in nuclear power plants.
    Issuance of DG-1303, if finalized, would not constitute backfitting 
as defined in section 50.109 of title 10 of the Code of Federal 
Regulations (10 CFR) 50.109, ``Backfitting,'' and as described in NRC 
Management Directive (MD) 8.4, ``Management of Backfitting, Forward 
Fitting, Issue Finality, and Information Requests''; constitute forward 
fitting as that term is defined and described in MD 8.4; or affect the

[[Page 5269]]

issue finality of any approval issued under 10 CFR part 52. As 
explained in DG-1303, applicants and licensees would not be required to
