ion Facilities,” require that structures, systems, and components (SSCs) important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. Appendix A to 10 CFR Part 50 states that where generally recognized codes and standards are used, they shall be identified and evaluated to determine their applicability, adequacy, and sufficiency, and shall be supplemented or modified as necessary to assure a quality product in keeping with the required safety function. Appendix A, “General Design Criteria for Nuclear Power Plants,” to 10 CFR Part 50 also requires that a quality assurance (QA) program be established and implemented in order to provide adequate assurance that these SSCs will satisfactorily perform their safety functions. Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” to 10 CFR Part 50 specifies criteria for the QA program to provide adequate confidence that SSCs will perform their safety- related functions satisfactorily in service. The review under this SRP section will be performed to assure conformance with the environmental design basis requirements of 10 CFR Part 50, Appendix A, General Design Criterion (GDC) 4, “Environmental and Dynamic Effects Design Bases,” which states, in part, that “Structures, systems, and components important to safety shall be designed to accommodate the effects of and to be compatible with the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents.” The review will assure conformance with the applicable portions of other relevant regulations, including 10 CFR Part 50, Appendix A, GDC 1, “Quality Standards and Records,” GDC 2, “Design Bases for Protection Against Natural Phenomena.” and GDC 23, “Protection System Failure Modes”; and 10 CFR Part 50, Appendix B, Quality
