asing, installing, testing, operating, maintaining, or modifying, that affect the safety-related functions of such structures, systems, and components. Further, Criterion III, “Design Control,” of Appendix B requires, in part, that design changes shall be subject to design control measures commensurate with those applied to the original design. Such design control measures shall provide for the ability to check the adequacy of the design by use of alternate or simplified calculation methods or by the performance of a suitable testing program. DG-1206, Page 2 In 10 CFR 50.55a(a)(1), the NRC requires, in part, that systems and components be designed, fabricated, erected, tested, and inspected to quality standards commensurate with the safety function to be performed. The regulations in 10 CFR 50.55a(h) require that reactor protection and safety systems satisfy the criteria in Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.) 603-1991, “IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations” (including a correction sheet dated January 30, 1995) (Ref. 2), or in IEEE Std. 279-1971, “Criteria for Protection Systems for Nuclear Power Generating Stations” (Ref. 3). These criteria shall be part of the evaluation of the recognized quality codes and standards selected for their applicability, adequacy and sufficiency and shall be supplemented or modified as needed to assure a quality product and that it will perform the required safety function. The guidance on the safety systems equipment employing digital computers, and programs or firmware requires quality standards in the use of software configuration management. This regulatory guide endorses IEEE Std. 828-2005, “IEEE Standard for Software Configuration Management Plans,” issued 2005 (Ref. 4), with the exceptions stated in the staff regulatory guidance. IEEE Std. 828-2005 describes methods acceptable to the NRC staff for use in complying with the NRC’s
