r any departures for the cited positions. Alternative tests that have been accepted by the branch include the use of ASTM A-708. The methods of controlling and measuring the amount of delta ferrite in stainless steel weld deposits are examined by the reviewer and compared to the positions in Regulatory Guide 1.31, "Control of Ferrite Content in Stainless Steel Weld Metal," especially with respect to the filler metal acceptance procedures for the determination of delta ferrite content. If 4.5.1-4 Rev 2 - July 1981 alternative positions are proposed by the applicant, the reviewer determines if these are satisfactory, taking into account branch posi- tions taken on previous applications. The reviewer may ask the applicant to justify the technical basis for any departures from the acceptance criteria stated in subsection II.2 of this SRP section. 3. Other Materials The reviewer examines the information provided in the applicant's safety analysis report (SAR) on the compatibility of the materials (other than austenitic stainless steels) to be used in contact with the reactor coolant. He determines that the materials are compatible with the service environment so that corrosion or stress corrosion of the com- ponent will not occur during the lifetime of the component. Metallic and nonmetallic materials identified in subsection 1.3 of this SRP section are reviewed to assure compatibility and that loss of integrity will not occur during the life of the component. The reviewer determines that the tempering temperatures of all martensitic stainless steels and the aging temperatures of precipitation- hardening stainless steels have been specified and are in accordance with the acceptance criteria in subsection II.3 of this SRP section. 4. Cleaning and Cleaniness Control The reviewer verifies that onsite cleaning and cleanliness control procedures are satisfactory and in accordance with subsection II.4 of this SRP section. IV. EVALUATION FINDINGS When the reviewer has verified
