ation provided in NUREG-0313. Similar recommendations related to minimizing stress corrosion cracking in susceptible piping of BWRs are described in NUREG-0313.71 Regulatory Guide 1.44 also identifies acceptable methods for verification of non-sensitization of austenitic stainless steel materials and qualification of welding processes employed in production including testing using ASTM A-262 Practice A or E (Reference 22) or another method which can be demonstrated to show non-sensitization. Alternative tests that have been previously accepted, based upon the adequacy of justifications presented and circumstances of proposed use, include the use of ASTM A-708 (Reference 23). (Applicable to 72 materials reviewed by MTEB as specified in item I.4.a.)73 5.2.3-11 DRAFT Rev. 3 - April 1996 b. The requirements of GDC 4 relative to compatibility of components with environmental conditions are met regarding additional controls to avoid stress corrosion cracking in austenitic stainless steels. These controls consist of acceptance criteria on prevention of contamination, cleaning, and upper limit on yield strength. Additional controls for avoiding stress corrosion cracking are applied to BWRs as described below.74 Controls to avoid stress corrosion cracking in austenitic stainless steels are also covered in Regulatory Guide 1.44. This guide provides acceptance criteria on the cleaning and protection of the material against contaminants capable of causing stress corrosion cracking. Acid pickling is to be avoided on fabricated stainless steels. Necessary pickling is to be done only with appropriate controls. Pickling should not be performed upon sensitized stainless steels. (Applicable to materials reviewed by MTEB as specified in item I.4.b.)75 The quality of water used for final cleaning or flushing of finished surfaces during installation is in accordance with Regulatory Guide 1.37, "Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of
