f Low-Alloy Steel Components," provide the acceptance criteria to avoid underclad cracking of stainless steel clad ferritic components. d. ASME Code Sections III and IX criteria for welding austenitic stainless steels are supplemented by the regulatory positions in Regulatory Guide 1.31, "Control of Ferrite Content in Stainless Steel Weld Metal," and Regulatory Guide 1.34. For the BWR austenitic stainless steel reactor vessel attachments and appurtenences specified in Generic Letter 88-01 (Reference 23), the weld metal ferrite content should be controlled as described in the positions of Attachment A to Generic Letter 88-01 or the recommendations of NUREG-0313 (Reference 21).33 5.3.1-7 DRAFT Rev. 2 - April 1996 e. The regulatory positions of Regulatory Guides 1.44, "Control of the Use of Sensitized Stainless Steel," and 1.37 , "Quality Assurance Requirements for 34 Cleaning of Fluid Systems and Associated Components of Water-Cooled Nuclear Power Plants," provide the acceptance criteria to avoid sensitization and contamination of stainless steel. Regulatory Guide 1.44 states that non-sensitization should be verified using ASTM A 262 (Reference 25) Practices A or E, or another method that can be 35 demonstrated to show non-sensitization of austenitic stainless steel. Alternative tests to those in ASTM A-262 that has been previously accepted include ASTM 36 A 708 (Reference 26). For BWRs, the control of sensitized steel per Regulatory 37 Guide 1.44 should be modified as necessary to conform with the positions in Attachment A to Generic Letter 88-01 or the recommendations of NUREG- 0313.38 The controls for abrasive work on austenitic stainless steel surfaces should, as a minimum, be equivalent to the controls described in Regulatory Guide 1.37 position C.5 to prevent contamination which promotes stress corrosion cracking. Tools which contain materials that could contribute to intergranular or stress-corrosion cracking or which, because of previous usage, may have become
