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.
