Additional Information

The NRC is issuing for public comment a draft 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 agency'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.

The DG, titled “Fire Protection for Nuclear Power Plants,” is temporarily identified by its task number, DG-1359 (ADAMS Accession No. ML20231A835). The draft guide DG-1359 is a proposed Revision 4 of RG 1.189. 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 (NEI) 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.)

The staff is also issuing for public comment a draft regulatory analysis (ADAMS Accession No. ML20231A874). The staff develops a regulatory analysis to assess the value of issuing or revising a regulatory guide as well as alternative courses of action.

II. Backfitting, Forward Fitting, and Issue Finality

DG-1359, if finalized, would provide the most recent guidance acceptable to the NRC staff for compliance with section 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 DG-1359, if finalized, would not constitute backfitting, as that term is defined in 10 CFR 50.109, “Backfitting,” and as described in NRC Management Directive 8.4, “Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests”; constitute forward fitting, as that term is defined and described in Management Directive 8.4; or affect the issue finality of any approval issued under 10 CFR part 52. As explained in DG-1359, applicants and licensees would not be required to comply with the positions set forth in DG-1359.
