ing, establishing and implementing a quality assurance (QA) program for the design and construction of nuclear power plants and fuel reprocessing plants licensed or approved under 10 CFR Part 50 or 10 CFR Part 52. • 10 CFR 50.54(a)(3)–(4) establishes how licenses may make changes to their QA programs in conditions to be included in every nuclear power reactor operating license issued under 10 CFR Part 50 and every combined license issued under 10 CFR Part 52. • 10 CFR Part 50, Appendix B, Criterion III, “Design Control,” includes the provisions for QA and quality control that are applicable to the acceptance and dedication process for commercial-grade digital I&C items. Criterion III fulfills the 10 CFR Part 50, Appendix B, requirement established by the definition of dedication in 10 CFR Part 21 for commercial-grade dedication programs. Criterion III design control requires, in part, measures for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems, and components. These measures are applicable to a commercial-grade digital equipment for use as a basic component in a digital I&C system. • 10 CFR 52.79(a)(25) requires applicants for combined licenses to include a description of the QA program, applied to the design, and to be applied to the fabrication, construction, and testing, of the structures, systems, and components of the facility. It notes that Appendix B to 10 CFR part 50 sets forth the requirements for QA programs for nuclear power plants. The description of the QA program for a nuclear power plant must include a discussion of how the applicable requirements of appendix B to 10 CFR part 50 have been and will be satisfied, including a discussion of how the QA program will be implemented.
