Content:
Methods - Regulatory Guide 1.172 provides a basis for evaluating conformance with 10 CFR 50.55a(h), GDC 1, and Criterion III of 10 CFR Part 50 Appendix B for computer-based systems. It endorses, with comments, IEEE Std. 830-1993 as describing an acceptable approach to the development of software requirements specifications. SRP BTP 7-14 describes the review of software requirements specifications. (p) Regulatory Guide 1.173, “Developing Software Life Cycle Processes for Digital Computer Software Used in Safety Systems of Nuclear Power Plants” (endorses IEEE Std. 1074-1995, “IEEE Standard for Developing Software Life Cycle Processes”) Applicability - All I&C systems and components important to safety. Review Methods - Regulatory Guide 1.173 provides a basis for evaluating conformance with 10 CFR 50.55a(h), GDC 1, and Criteria I, II, III, VI, XV, and XVII of 10 CFR 50 Appendix B for computer-based systems. It endorses, with comments, IEEE Std. 1074-1995 as providing acceptable approaches to defining software development processes. SRP BTP 7-14 describes the review of software development plans and software project management plans that should outline the licensee/applicant’s software life cycle. SRP BTP 7-14 also describes the review of each activity group described in IEEE Std. 1074-1995. (q) Regulatory Guide 1.174, “An Approach for Using Probabilistic Risk Assessment Risk-Informed Decisions on Plant-Specific Changes to Licensing Basis.” Applicability - All I&C Systems. Review Methods - Regulatory Guide 1.174 provides a basis for the conformance to GDC 13 as part of the evaluation of I&C surveillance test interval changes for purposes other than the accommodation of a 24 month fuel cycle change. Regulatory Guide 1.174 provides guidance on the use of probabilistic risk assessment (PRA) findings and risk insights in support of licensee requests for changes to a plant’s licensing basis, as in requests for licensing amendments and technical specification
