REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of materials engineering issues related to flaw evaluation and welding Secondary - None I. AREAS OF REVIEW This Standard Review Plan (SRP) section provides guidance for reviewing and evaluating the adequacy of an applicant’s criteria in regard to selection of materials, design, inspection and testing of its threaded fasteners (i.e., threaded bolts, studs, etc.) prior to initial service and during service. The scope of this chapter is limited to the review of threaded fasteners in American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (Code) Class 1, 2 or 3 systems. The staff’s review in this SRP chapter focuses on the information provided in Chapter 3.13 of the Safety Analysis Report (SAR). The specific areas of review are as follows: 1. Design Aspects A. Materials Selection The staff reviews information pertaining the selection of materials and material testing of threaded fasteners that are categorized as ASME Code Class 1, 2, or 3. 3.13-2 March 2007 The scope of the review includes material selection considerations and conformance with applicable codes or standards. B. Mechanical Testing, Special Process and Controls The staff reviews information in the SAR pertaining to the fabrication of threaded fasteners that have been selected for ASME Code Class 1, 2, and 3 systems. The scope of the review includes fabrication practices or special processes used to mitigate the occurrence of stress corrosion cracking (SCC) or other forms of material degradation in the fasteners during service. The staff reviews information pertaining to the environmental considerations that should be accounted for when selecting materials of fabrication for threaded fasteners. The scope of the review includes any information in the SAR or submitted by the applicant that pertains to the use of lubricants and/or surface treatments in mechanical connections secured by threaded fasteners and
