tance criteria discussed in Subsection II.4.B of this SRP section. The applicant's description of abrasive work controls for austenitic stainless steel surfaces is reviewed and is verified adequate to minimize the introduction of stress corrosion cracking promoting contaminants and the cold-working of surfaces. Because excessive cold work in austenitic stainless steel can render this material susceptible to stress corrosion cracking, control must 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. For BWRs, particular review emphasis is placed upon verification of conformance to the positions of Generic Letter 88-01 or the recommendations of NUREG- 0313, Revision 2 as applicable. 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 such material specified by the applicant is in conformance with the acceptance criteria stated in Subsection II.4.C of this SRP section. Verification is obtained that the material has been chemically analyzed by methods equivalent to those prescribed in Regulatory Guide 1.36 and that evidence is obtained that the levels of leachable contaminants are such that stress corrosion of stainless steel will not result from use of the insulation. D. The information submitted by the applicant regarding control of delta ferrite in austenitic stainless steel welds is reviewed to determine its conformance with the acceptance criteria stated in Subsection II.4.D of this SRP section. The reviewer verifies that
