II. 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 and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC'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 draft regulatory guide, entitled, “ASME Code Cases not Approved for Use,” is temporarily identified by its task number, DG-1233 (ADAMS Accession No. ML13114A948). The DG-1233 is proposed Revision 4 of Regulatory Guide 1.193. Revision 3 of Regulatory Guide 1.193 was published in October 2010 (ADAMS Accession No. ML101800540).

The purpose of RG 1.193 is to provide information for applicants and licensees regarding the ASME Boiler and Pressure Vessel Code (BPV) and Operation and Maintenance (OM) of nuclear power plants Code Cases that the NRC has determined not to be acceptable for use on a generic basis.

Regulatory Guide 1.193 lists the Code Cases that the NRC has determined not to be acceptable for use on a generic basis. A brief description of the basis for the determination is provided with each Code Case. There are three other RGs that list the Code Cases that the NRC has found to be acceptable alternatives to requirements in the ASME BPV and OM Codes.

In the Proposed Rules section of this issue of the Federal Register, a notice of issuance and availability addresses the RGs listing the ASME BPV and OM Code Cases that the NRC has approved for use by applicants and licensees: RG 1.84, Revision 36, “Design, Fabrication, and Materials Code Case Acceptability, ASME Section III”; RG 1.147, Revision 17, “Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1”; and RG 1.192, Revision 1, “Operation and Maintenance Code Case Acceptability, ASME OM Code.” The aforementioned notice is available at www.regulations.gov by searching on Docket ID NRC-2009-0359.

Regarding draft Revision 4 of RG 1.193, the NRC reviewed the Code Cases listed in Supplements 1 through 10 of the 2007 Edition of the BPV Code and the 2002 through 2006 Addenda of the OM Code. Licensees may submit a request to implement one or more of the Code Cases listed in RG 1.193 through § 50.55a(z) of Title 10 of the Code of Federal Regulations (10 CFR), which permits the use of alternatives to the Code requirements referenced in 10 CFR 50.55a provided that the proposed alternatives result in an acceptable level of quality and safety. Licensees must submit a plant-specific request that addresses the NRC's concerns about the Code Case at issue.

In the Proposed Rules section of this issue of the Federal Register, a proposed rule that would incorporate by reference RGs 1.84, 1.147, and 1.192 into 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities” (RIN 3150-AI72; NRC-2009-0359). The statement of considerations for the proposed rule lists the acceptable and conditionally acceptable Code Cases, and discusses the bases for the proposed conditions.

III. Backfitting and Issue Finality

The purpose of this section is to provide information to applicants and licensees regarding the NRC staff's plans for using this regulatory guide. This regulatory guide does not approve the use of the Code Cases listed herein. Licensees may submit a plant-specific request to implement one or more of the Code Cases listed in this regulatory guide. The request must address the NRC's concerns about the Code Case at issue.
