The U.S. Nuclear Regulatory Commission (NRC) has issued for public comment a draft of a revised guide in the agency's Regulatory Guide Series. This series has been 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 Revision 2 of Regulatory Guide 1.193, “ASME Code Cases Not Approved for Use,” is temporarily identified by its task number, DG-1135, which should be mentioned in all related correspondence. Like its predecessors, this proposed revision lists the Code Cases that the NRC has determined are not acceptable for generic use as specified in Section III, “Rules for Construction of Nuclear Power Plant Components,” and Section XI, “Rules for Inservice Inspection of Nuclear Power Plant Components,” of the Boiler and Pressure Vessel (BPV) Code promulgated by the American Society of Mechanical Engineers (ASME). (In so doing, this guide complements Revision 34 of Regulatory Guide 1.84, “Design, Fabrication, and Materials Code Case Acceptability, ASME Section III,” and Revision 15 of Regulatory Guide 1.147, “Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1,” which list the Code Cases that the NRC has determined to be acceptable alternatives to applicable provisions of Section III and Section XI, respectively.)
Licensees may request NRC approval to implement one or more of the Code Cases listed in Revision 2 of Regulatory Guide 1.193, as provided in 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. To do so, a licensee must submit a plant-specific request that addresses the NRC's concern about the given Code Case.
The NRC staff is soliciting comments on Draft Regulatory Guide DG-1135, and comments may be accompanied by relevant information or supporting data. Please mention DG-1135 in the subject line of your comments.
