The NRC is issuing Regulatory Guide (RG) 1.193 in the agency's “Regulatory Guide” series. This series was developed to describe and make available to the public specific program information. This information includes methods acceptable to the NRC staff for implementing specific parts of the agency's regulations, techniques the staff uses in evaluating specific problems or postulated accidents, and data the staff needs in its review of applications for permits and licenses.
RG 1.193 lists the Code Cases that NRC has determined not to be acceptable for use on a generic basis. Two separate RGs list Code Cases that NRC has found to be acceptable alternatives to requirements in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. RG 1.84, Rev. 35, “Design, Fabrication, and Materials Code Case Acceptability, ASME Section III,” lists all Section III Code Cases that NRC has approved for use. RG 1.147, Rev. 16, “Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1,” lists all Section XI Code Cases that NRC has approved for use. RG 1.84 and RG 1.147 are being noticed under a separate notice of availability.
For Revision 3 of RG 1.193, NRC reviewed the Code Cases listed in Supplements 2-11 to the 2004 Edition of the ASME Boiler and Pressure Vessel (BPV) Code and Supplement 0 to the 2007 Edition (Supplement 0 also serves as Supplement 12 to the 2004 Edition). A brief description of the basis for the unacceptability determination is provided with each Code Case in RG 1.193. Licensees may submit a request to implement one or more of the Code Cases listed in RG 1.193 through 10 CFR 50.55a(a)(3), 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 NRC's concerns about the Code Case at issue.
