ergency core cooling such that damage to reactor core components is minimal following any loss of reactor coolant. It also requires that the system will have containment capabilities to DRAFT Rev. 3 - April 1996 10.3.6-4 assure that the emergency core cooling function can be accomplished, assuming a single failure. For pressure containing components of a critical nature, their containment capability, i.e., their structural integrity, including freedom from brittle fracture, can only be assured by requiring minimum fracture toughness performance of the materials of which they are fabricated. This is a standard industrial practice which is frequently used in construction codes of significant steel structures. C3. 10 CFR Part 50, Appendix B - "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants." This appendix establishes quality assurance requirements for the design, construction, and operation of those structures, systems, and components of nuclear power plants that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health and safety of the public. (Ref. 5) 24 The following Regulatory Guides provide information, recommendations, and guidance and in general describe a basis acceptable to the staff that may be used to implement the requirements of 10 CFR Part 50, §50.55a; 10 CFR Part 50, Appendix A, General Design Criteria 1 and 35; 10 CFR Part 50, Appendix B. 25 a. Regulatory Guide 1.37, "Quality Assurance Requirements for Cleaning of Fluid Systems and Associated Components of Water-Cooled Nuclear Power Plants." This guide 26 describes methods acceptable to the staff for prevention of intergranular and stress corrosion cracking of austenitic stainless steel and nickel-base alloy components. b. Regulatory Guide 1.71, "Welder Qualification for Areas of Limited Accessibility." This guide describes methods acceptable to the staff for providing better control of welder technique in production
