trical Safety Systems” (endorses IEEE Std 384). Applicability - All I&C systems. Review Methods - RG 1.75 provides a basis for evaluating conformance to GDC 21 and IEEE Std 279-1971, Clauses 4.6 and 4.22, and for evaluating the adequacy of I&C systems important to safety that incorporate redundant or diverse features to satisfy the single-failure criterion. The guidance applies equally to IEEE Std 603-1991, Clauses 5.6 and 5.11. The I&C evaluation is limited to the review of components and electrical wiring inside racks, panels, and control boards for systems important to safety. The evaluation of the physical separation of electrical cables is addressed in the review of Chapter 8 of the SAR. (f) RG 1.97, Revisions 2 and 3, “Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess Plant and Environs Conditions During and Following an Accident” (endorses American National Standards Institute (ANSI)/American Nuclear Society (ANS) -4.5, “Criteria for Accident Monitoring Functions in Light- Water-Cooled Reactors”), and RG 1.97, Revision 4, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants” (endorses IEEE Std 497, Appendix 7.1-A-30 Draft Revision 6 – August 2015 “IEEE Standard Criteria for Accident Monitoring Instrumentation for Nuclear Power Generating Stations”). Applicability - Information systems important to safety. Review Methods - RG 1.97 provides a basis for evaluating conformance to GDC 13. Existing plants currently reference Revision 2 or 3 of RG 1.97. Revision 4 of RG 1.97 is intended primarily for new plants. Revision 4 may be used by the current operating reactor licensees for modification or conversion in accordance with Regulatory Position 1 of RG 1.97. Revision 4 to RG 1.97 represents a significantly different approach to the topic from the previous revisions. Revision 4 is based on IEEE Std 497, which establishes flexible, performance-based criteria for the selection, performance, design,
