GDC 30, and §50.55a regarding quality standards are met for material specifications by compliance with the applicable provisions of the ASME Code and by compliance with the recommendationsacceptable application of materials Code Cases ofas described in Regulatory Guide 1.85, "Materials Code Case Acceptability ASME Section III Division 1."44 The specifications for permitted materials are those identified in the ASME Code, Section III, Appendix I, or described in detail in the ASME Code, Section II, "Materials" (Reference 21), Parts A, B, and C. Regulatory Guide 1.85, "Code Case Acceptability 45 ASME Section III Materials," describes the acceptable materials Code Cases and guidelines for their application in light-water-cooled nuclear power plants to bewhich may be used in conjunction with the above specifications. (Applicable to materials 46 reviewed in item I.1 by MTEB.)47 Special requirements for BWR piping materials and materials processing are described in Attachment A to Generic Letter 88-01 (Reference 19). The technical bases for the positions provided in Generic Letter 88-01 and similar recommendations related to minimizing stress corrosion cracking in susceptible piping of BWRs are detailed in NUREG-0313, "Technical Report on Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping." (Reference 18).48 2. Compatibility of Materials with the Reactor Coolant The requirements of GDC 4 relative to compatibility of components with 49 environmental conditions are met by compliance with the applicable provisions of the DRAFT Rev. 3 - April 1996 5.2.3-8 ASME Code and by compliance with the recommendationspositions of Regulatory 50 Guide 1.44, "Control of the Use of Sensitized Stainless Steel."51 Ferritic low alloy steels and carbon steels, which are used in many principal pressure-retaining components, are clad with a layer of austenitic stainless steel. If cladding is not used, conservative corrosion allowances must be indicated for all
