” provides guidance for evaluating conformance to the requirements of IEEE Std 279-1971. 7.8-6 Revision 6 – August 2016 3. SRP Appendix 7.1-C, “Guidance for Evaluation of Conformance to IEEE Std 603,” provides guidance for evaluating conformance to IEEE Std 603-1991. 4. 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 Digital 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.” III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. Typical reasons for a non-uniform emphasis are the introduction of new design features or the use in the design of features previously reviewed and found acceptable. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. SRP Section 7.1, “Instrumentation and Controls – Introduction,” describes the general procedures to be followed in reviewing any I&C system. This part of SRP Section 7.8, “Diverse Instrumentation and Control Systems,” highlights specific topics that should be emphasized in the diverse I&C systems review. The diverse I&C systems review should address the applicable topics identified in SRP Table 7-1. SRP Appendix 7.1-A describes review methods for each topic. Major design considerations that should be emphasized in the review of the diverse I&C systems are identified below. • Design basis - Design bases should be described in the SAR for each diverse I&C system. The design
