Content:
ety system requirements and those requirements defined at each stage of development, including handling of credible abnormal conditions, have been implemented. Implementation of a software engineering process as described by BTP HICB-14 will ensure adequate verification and validation. Reg. Guides 1.168, "Verification, Validation, Reviews and Audits for Digital Computer Software Used in Safety Systems of Nuclear Power Plants," 1.170, "Software Test Documentation for Digital Computer Software Used in Safety Systems of Nuclear Power Plants," and 1.171, "Software Unit Testing for Digital Computer Software Used in Safety Systems of Nuclear Power Plants," describe acceptable approaches to planning and conducting certain verification and validation activities of a software engineering process. e. Software configuration management — As described in Section 5.3.5 of IEEE Std 7-4.3.2, an acceptable software development process will include software configuration management in accordance with ASME NQA-2a Part 2.7. BTP HICB-14 describes the characteristics that the Staff expects software configuration management processes will exhibit. Reg. Guide 1.169, "Configuration Management Plans for Digital Computer Software Used in Safety Systems of Nuclear Power Plants," describes an acceptable method for implementing software configuration management. 3. Equipment qualification — To comply with the requirements of GDC 4, 10 CFR 50.49, and ANSI/IEEE Std 279 Sections 3.7, 4.4, & 4.5, environmental qualification must demonstrate that the design basis and performance requirements of the I&C system are met when the equipment is exposed to normal and adverse environments. SRP Appendices 7.1-B and 7.1-C describe the review of qualification for all environments. 4. System integrity — ANSI/IEEE Std 279, Section 4.5 and GDC 21 require that all protection system channels maintain necessary functional capability under extremes of conditions relating to environment, energy supply,
