7-17 provides additional guidance on acceptable periodic testing provisions for digital computer-based systems. (b) RG 1.47, “Bypassed and Inoperable Status Indication for Nuclear Power Plant Safety Systems” Applicability - RTS, ESFAS, information systems important to safety, safety interlock systems, and supporting data communications systems. Appendix 7.1-A-29 Draft Revision 6 – August 2015 Review Methods - RG 1.47 provides bases for evaluating conformance to GDC 21 and IEEE Std 279-1971, Clauses 4.13 and 4.20, for protection systems. The guidance applies equally to IEEE Std 603-1991, Clauses 5.8.2 and 5.8.3. The RG also provides bases for evaluating the adequacy of bypass and inoperable status indication for I&C systems important to safety as addressed in the review of Section 7.5 of the SAR. (c) RG 1.53, “Application of the Single-Failure Criterion to Nuclear Power Plant Protection Systems” (endorses IEEE Std 379, “Standard Application of the Single-Failure Criterion to Nuclear Power Generating Station Safety Systems”) Applicability - All I&C safety systems and supporting data communications systems. Review Methods - RG 1.53 provides a basis for evaluating conformance to GDC 21 and IEEE Std 279-1971, Clause 4.2. The guidance applies equally to IEEE Std 603-1991, Clause 5. (d) RG 1.62, “Manual Initiation of Protection Action” Applicability - RTS, ESFAS, and diverse I&C systems. Review Methods - RG 1.62 provides a basis for evaluating conformance to IEEE Std 279-1971, Clause 4.17. The guidance applies equally to IEEE Std 603-1991, Clauses 6.2 and 7.2. RG 1.62 also provides guidance that should be considered in the review of manual initiation of ATWS mitigation and diverse actuation system functions. (e) RG 1.75, “Criteria for Independence of Electrical 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
