2 recommendations, and 1.37, "Quality Assurance 116 Requirements for Cleaning of Fluid Systems and Associated Components of Water Cooled Nuclear Plants." The controls followed in accordance with these recommendations, during material selection, fabrication, examination, and protection, in order to prevent excessive yield strength, sensitization, and contamination, provide reasonable assurance that the RCPB components of austenitic stainless steels will be in a metallurgical condition that minimizes susceptibility to stress corrosion cracking during service. These controls meet the requirements of GDC 4 relative to compatibility of components with environmental conditions and the requirements of GDC 14 relative to prevention of leakage and failure of the RCPB. The controls imposed during welding of austenitic stainless steels in the RCPB are in accordance with the recommendations of Regulatory Guide 1.31, "Control of Ferrite Content in Stainless Steel Weld Metal,"; [for BWRs only] the positions of Generic Letter 88-01 and/or the recommendations of NUREG-0313, Revision 2; Regulatory Guide 1.34,; and Regulatory Guide 1.71. These controls provide reasonable assurance that 117 welded components of austenitic stainless steel will not develop microfissures during welding and will have high structural integrity. These controls meet the quality standards requirements of GDC 1, GDC 30, and §50.55a and satisfy the requirements of GDC 14 relative to prevention of leakage and failure of the RCPB. The fabrication controls for cast austenitic stainless steel components, in conjunction with acceptable base material and weld metal specifications, provide for welded joint inspectability and adequate fracture toughness to resist thermal aging for the design life. These controls therefore satisfy the applicable requirements of GDC 1, GDC 4, GDC 14, GDC 30, and §50.55a.118 5.2.3-23 DRAFT Rev. 3 - April 1996 For design certification reviews, the findings will also summarize, to the
