protective action. - Time when automatic control of protective action is required. - Time when protective system may be returned to normal. • Clause 6.1 - timely automatic control action is required when events occur too quickly for operator intervention. SRP, Appendix 7.1-B, “Guidance for Evaluation of Conformance to IEEE Std 279,” provides guidance for evaluating conformance to the requirements of IEEE Std 279-1971. BTP 7-21-4 Revision 6 – August 2016 SRP Appendix 7.1-C, “Guidance for Evaluation of Conformance to IEEE Std 603,” provides guidance for evaluating conformance to IEEE Std 603-1991. SRP Appendix 7.1-D, “Guidance for Evaluation of the Application of IEEE Std 7-4.3.2,” provides guidance for evaluating conformance to the acceptance criteria contained in RG 1.152, “Criteria for Use of Computers in Safety Systems of Nuclear Power Plants,” which endorses IEEE Std 7-4.3.2, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations.” IEEE Std 7-4.3.2, Clause 2, states that this standard shall be used in conjunction with additional standards, including: • IEEE Std 1012-1998, “IEEE Standard for Software Verification and Validation.” • IEEE/EIA 12207.0-1996, “Standard Industry Implementation of International Standard ISO/IEC 12207: 1995 (ISO/IEC 12207) Standard for Information Technology Software Life Cycle Processes.” IEEE/EIA 12207.0-1996 is a software standard for organizing and managing software life cycle processes. This standard states in part: • Clause 5.3.4.1 - performance requirements shall be established and documented as part of software requirements analysis. • Clauses 5.3.5.6, 5.3.6.7, 5.3.7.5, 5.3.8.5, 5.3.9.3, 5.3.10.3 and 5.3.11.2 - software requirements, including performance requirements, shall be traced through architectural design, detailed design, coding, testing, software integration, software qualification testing, system integration, and system qualification
