Regulatory guide; issuance.
The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 2 to Regulatory Guide (RG) 1.57, “Design Limits and Loading Combinations for Metal Primary Reactor Containment System Components,” in which there are no substantive changes to the RG. The revision includes correction of a subsection title and editorial changes to improve clarity. This guide describes a method that the NRC staff considers acceptable for design limits and loading combinations for metal primary reactor containment system components.

The NRC is issuing a revision to an existing guide in the NRC's “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 typically seeks public comment on a draft version of a regulatory guide by announcing its availability for comment in the Federal Register. However, as explained on page 7 of NRC Management Directive 6.6 “Regulatory Guides,” (ADAMS Accession No. ML110330475) the NRC may directly issue a final regulatory guide without a draft version or public comment period if the changes to the regulatory guide are non-substantive.
The NRC is issuing Revision 2 of RG 1.57 (ADAMS Accession No. ML12325A043) directly as a final regulatory guide because the changes between Revision 1 and Revision 2 are non-substantive. The revision was to correct an error in a subsection title on page ten of Revision 1, which referred to the ultimate capacity of concrete containment structures when it should be steel containments, since metal primary reactor containment systems are the focus of this regulatory guide. In addition, Revision 1 specifically referred to Section 3.8.2, “Steel Containment” of NRC's Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants, NUREG-0800) (ADAMS Accession No. ML100630179) without further elaboration on the application of the guidance. This was corrected by importing the guidance found in NUREG-0800, Section 3, 8.2 into Revision 2 of RG 1.57. This did not change the staff's regulatory guidance. In addition, editorial changes were made to improve clarity and ADAMS Accession Numbers were added in the Start Printed Page 28897reference section to facilitate public access to the documents.
II. Backfitting and Issue Finality
Issuance of this final regulatory guide does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52. The changes in Revision 2 of RG 1.57 are limited to editorial changes to improve clarity and the correction of a title. 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 part 52. Accordingly, the NRC did not address the Backfit Rule or issue finality provisions of part 52.
III. Congressional Review Act
This regulatory guide is a rule as designated 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 designated in the Congressional Review Act.
IV. Submitting Suggestions for Improvement of Regulatory Guides
Revision 2 of RG 1.57 is being issued without public comment. However, you may at any time submit suggestions to the NRC for improvement of existing regulatory guides or for the development of new regulatory guides to address new issues. Suggestions can be submitted by the form available online at http://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html. Suggestions will be considered in future updates and enhancements of the regulatory guide.Start Signature
