6 2. Compatibility with Other Process Fluids The reviewer considers the composition of other process fluids to which ESF materials may be routinely exposed and the environmental conditions of exposure (e.g., temperature). The reviewer examines the information on the compatibility of the ESF materials of construction with the process fluids, including reactor coolant, to verify that all materials used are compatible. The reviewer coordinates this review with the review of compatibility and controls/limits for reactor coolant described in SRP Sections 5.4.8 and 9.3.4.97 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.98 IV. EVALUATION FINDINGS The staff concludes that the engineered safety features materials specified are acceptable and meet the requirements of GDC 1, 4, 14, 31, 35, and 41 of Appendix A of 10 CFR Part 50; Appendix B of 10 CFR Part 50, and 10 CFR Part 50, §50.55a. This conclusion is based on the following: 1. General Design Criteria 1, 14, and 31, and 10 CFR Part 50, §50.55a have been met with respect to assuring an extremely low probability of leakage, of rapidly propagating failure and of gross rupture. This is shown since the materials selected for the engineered safety features satisfy Appendix I of Section III, Division 1 of the ASME Code, and 99 Parts A, B, and C of Section II of the Code, and the staff position that the yield strength of cold-worked stainless steels shall be less than
