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.
