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 4 to RG 1.189 was issued with a temporary identification 
of Draft Regulatory Guide, DG-1359. This revision of the guide 
(Revision 4) addresses new issues identified since the guide was 
previously revised and released in 2018. This includes incorporation of 
the latest guidance on fire-induced circuit failures, multiple high 
impedance failures, open secondary circuits on current transformers, 
and shorting switches. Updates also include partial endorsements of 
Nuclear Energy Institute 00-01, ``Guidance for Post Fire Safe Shutdown 
Circuit Analysis,'' Revision 4, issued September 2016, and guidance 
based on NUREG/CR-7150, ``Joint Assessment of Cable Damage and 
Quantification of Effects from Fire (JACQUE-FIRE),'' Volumes 1, 2, and 
3 (ADAMS Accession Nos. ML12313A105, ML14141A129, and ML17331B098.)

II. Additional Information

    The NRC published a notice of the availability of DG-1359 in the 
Federal Register on November 16, 2020 (85 FR 73089) for a 45-day public 
comment period. The public comment period closed on December 31, 2020. 
Public comments on DG-1359 and the staff responses to the public 
comments are available in ADAMS under Accession No. ML21048A440.

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

    The issuance of RG 1.189, Revision 4, would provide the most recent 
guidance acceptable to the NRC staff for compliance with paragraph 
50.48(a) and (b) of title 10 of the Code of Federal Regulations (10 
CFR) and 10 CFR part 50, appendix R, ``Fire Protection Program for 
Nuclear Power Facilities Operating Prior to January 1, 1979.'' Issuance 
of RG 1.189, Revision 4, would not constitute backfitting, as that term 
is defined in 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 
issue finality of any approval issued under 10 CFR part 52. As 
explained in RG 1.189, Revision 4, applicants and licensees would not 
be required to comply with the positions set forth in RG 1.189, 
Revision 4.

    Dated: May 24, 2021.
