Nuclear Regulatory Commission.


Regulatory guide; revision.


The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 3 to Regulatory Guide (RG) 1.189, “Fire Protection for Nuclear Power Plants.” Revision 3 of RG 1.189 includes administrative changes involving editorial corrections that make the document consistent with existing policy. None of the revisions involve changes to the staff regulatory positions. This guide describes a method that the NRC staff considers acceptable to meet regulatory requirements for fire protection in nuclear power plants.

I. Discussion

The NRC is issuing a revision to an existing guide in the NRC “Regulatory Guide” series. Regulatory guides were developed to describe and make available to the public information methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

The NRC is issuing Revision 3 of RG 1.189 directly as a final RG, because the changes between Revision 2 and Revision 3 are administrative and non-substantive. Revision 3 of RG 1.189 also updated the guide to the current program guidance for RGs. The NRC added language to Section 1, “Fire Protection Program,” to clarify the primary objectives of fire protection plans.

Since the issuance of Revision 2 of RG 1.189 in 2009, the NRC issued a Regulatory Issuance Summary to inform licensees that Inspection Manual Part 9900, Technical Guidance (TG 9900), “Operability Determinations & Functionality Assessments for Resolution of Degraded and Nonconforming Conditions Adverse to Quality and Safety,” was reissued as Inspection Manual Chapter (IMC) 0326, “Operability Determinations and Functionality Assessments for Conditions to Quality or Safety,” dated January 31, 2014. Revision 3 of RG 1.189 now includes a reference to IMC 0326 (see Section 1.5, “Compensatory Measures”).

Revision 3 of RG 1.189 also corrects typographic errors that previously appeared in Section 1.7.7, “Nonconforming Items,” Section 1.7.4, “Inspection,” Section 2.1.1, “Transient Fire Hazards,” Section 3.2.1, “Fire Protection Water Supply,” and Section 3.2.3, “Fire Mains.” Previously, these errors occurred during publishing of the final regulatory guide, when several paragraphs were incorrectly indented, resulting in incorrect sub-bullet numbering. These changes are intended to improve clarity and do not substantially alter the staff's regulatory guidance.

II. Backfitting and Issue Finality

Issuance of this final RG does not constitute backfitting as defined in section 50.109 of title 10 of the Code of Federal Regulations (10 CFR), (the Backfit Rule), and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52. The changes in Revision 3 of RG 1.189 are limited to editorial changes to improve clarity and correct errors. These changes do not fall within the kinds of agency actions that constitute backfitting or are subject to limitations in the issue finality provisions of 10 CFR part 52. Accordingly, the NRC did not address the Backfit Rule or issue finality provisions of 10 CFR part 52.

III. Congressional Review Act

Revision 3 of Regulatory Guide 1.189 is not a rule as defined in the Congressional Review Act (5 U.S.C. 801-808).

IV. Submitting Suggestions for Improvement of Regulatory Guides

Revision 3 of RG 1.189 is being issued without public comment. However, a member of the public may, at any time, submit suggestions to the NRC for improvement of existing RGs or for the development of new RGs to address new issues. Suggestions can be submitted on the NRC's public website at​reading-rm/​doc-collections/​reg-guides/​contactus.html. Suggestions will be considered in future updates and enhancements to the “Regulatory Guide” series.
