at or supplying steam to engineered safety feature (ESF) pumps. This SRP evaluates steam and feedwater materials including material fracture toughness properties. By verifying that steam and feedwater system materials meet GDC 35 requirements, assurance is provided that steam and feedwater system integrity will be maintained, thereby allowing these systems to fulfill their safety functions of removing decay heat and supplying steam to ESF pumps. 3. Appendix B of 10 CFR Part 50 provides quality assurance requirements for the design, construction, and operation of safety-related SSCs of a nuclear plant. The steam and feedwater systems may be relied upon to perform safety functions such as removing decay heat or supplying steam to engineered safety feature pumps. Regulatory Guide 1.37 provides acceptable quality assurance procedures for cleaning and handling of safety-related materials. Meeting the criteria of 10 CFR Part 50, Appendix B, and the positions of Regulatory Guide 1.37, provides assurance that the steam and feedwater system materials are designed and selected to established quality assurance standards, thus providing a high degree of certainty that safety functions will be performed and the health and safety of the public will be protected. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Materials Selection and Fabrication of Class 2 and 3 Components. The reviewer determines that the materials proposed for the steam and feedwater systems are in conformance with Appendix I to Section III and to Parts A, B, and C of Section II of the Code. A.
