ion in which functional reliability is a goal. Consequently, although these standards are not SRP acceptance criteria for nonsafety I&C systems, they are a source of design concepts that may be useful for the reviewer to consider. The scope of IEEE Std 603-1991 is broader than that of IEEE Std 279-1971, and the guidance of IEEE Std 603-1991 is consequently readily adaptable for use in the review of nonsafety I&C systems. 3. Location of Detailed Acceptance Criteria and Review Methods • SRP Appendix 7.1-A provides guidance on the applicability and review methods to be used in evaluating conformance to the regulatory requirements and SRP acceptance criteria for I&C systems important to safety. In three cases, the discussion of review methods is extensive and is located in separate appendices that are referenced by SRP Appendix 7.1-A. These appendices are: 7.1-7 Draft Revision 6 – August 2015 • SRP Appendix 7.1-B provides guidance for evaluating conformance to the requirements of IEEE Std 279-1971. • SRP Appendix 7.1-C provides guidance for evaluating conformance to IEEE Std 603-1991. • SRP Appendix 7.1-D 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.” 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 utilization 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
