SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a revision 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.
    Revision 2 to RG 1.205 was issued with a temporary identification 
of Draft Regulatory Guide, DG-1360. This revision of the guide 
(Revision 2) addresses new information identified since the guide was 
previously revised in 2009. This RG updates the previous staff 
positions and endorsements made regarding earlier versions of Nuclear 
Energy Institute (NEI) guidance documents, NEI-04-02, ``Guidance for 
Implementing a Risk-Informed, Performance-Based Fire Protection Program 
Under 10 CFR 50.48(c),'' and NEI 00-01, ``Guidance for Post Fire Safe 
Shutdown Circuit Analysis.'' This revision endorses NEI 04-02, Revision 
3, issued 2019, and portions of NEI-00-01, Revision 4, issued 2019, and 
includes guidance concerning fire-induced circuit failures.

II. Additional Information

    The NRC published a notice of the availability of DG-1360 in the 
Federal Register on November 16, 2020 (85 FR 73088) for a 45-day public 
comment period. The public comment period closed on December 31, 2020. 
Public comments on DG-1360 and the staff responses to the public 
comments are available in ADAMS under Accession No. ML21048A449.

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

    RG 1.205, Revision 2, would incorporate the latest information 
concerning risk-informed, performance-based fire protection programs 
and supporting guidance. Issuance of RG 1.205, Revision 2, would not 
constitute backfitting, as that term is defined in section 50.109 of 
title 10 of Code of Federal Regulations (CFR), ``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 issue finality of any approval 
issued under 10 CFR part 52. As explained in RG 1.205, Revision 2, 
applicants and licensees would not be required to comply with the 
positions set forth in RG 1.205, Revision 2.

    Dated: May 24, 2021.

Chief, Regulatory Guidance and Generic Issues Branch, Division of
