n the event that information in the above areas is not supplied, sufficient justification for the deviation must be presented. b. The information submitted by the applicant is reviewed for conformance with the acceptance criteria discussed in subsection II.4.b of this SRP section as follows: Verification is sought that process controls are exercised during all stages of component manufacture and reactor construction to minimize the exposure of austenitic stainless steels to contaminants that could lead to stress corrosion cracking. Information is also checked to assure that precautions have been taken, to require removal of all cleaning solutions, processing compounds, degreasing agents, and any other foreign material from the surfaces of the component at any stage of processing prior to any elevated temperature treatment and prior to hydrotests. The reviewer verifies that a statement is contained in the SAR that pickling of sensitized austenitic stainless is avoided and that the quality of water used for final cleaning or flushing of finished surfaces during installation is in accordance with acceptance criteria discussed in subsection IT 4.b. of this SRP section. Because excessive cold work in austenitic stainless steel can render this material susceptible to stress corrosion cracking, control must 5.2.3-12 Rev. 2 - July 1981 be exerted by the applicant, by placing an upper limit on the yield strength, in accordance with the acceptance criteria discussed in subsection II.4.b of this SRP section. Verification is obtained that the applicant has such a control measure. c. The information submitted by the applicant is reviewed to determine the type of insulation used and to determine its compatibility with the austenitic stainless steel used in construction of the component. There are no compatibility concerns with the use of reflective metal insulation; the chief compatibility concern is with the use of nonmetallic insulation. A review is performed to assure that any
