l," and additional criteria for BWRs are in NUREG-0313. (Applicable to materials reviewed by MTEB as specified in item I.4.a.) 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. -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.) 5.2.3-8 Rev. 2 - July 1981 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 Water Cooled Nuclear Power Plants." Vented tanks with deionized or demineralized water are an acceptable source of water for final cleaning or flushing of finished surfaces. The oxygen content* of the water need not be controlled. (Applicable to water specified in Regulatory Guide 1.44 used for final cleaning or flushing of finished stainless steel surfaces, and reviewed by CMEB.) Laboratory stress corrosion tests and service experience provide the basis for the criterion that cold-worked austenitic stainless steels used in the reactor coolant pressure boundary should have an upper limit on the yield strength of 90,000 psi. (Applicable to material reviewed by MTEB in item I.4.b.) c. The acceptance criteria for compatibility of
