f periodic testing in protection systems. SRP BTP 7-17, “Guidance on Self-Test and Surveillance Test Provisions,” 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. 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. Appendix 7.1-A-29 Revision 6 – August 2016 (e) RG 1.75, “Criteria for Independence of Electrical Safety Systems” (endorses IEEE Std 384). Applicability - All I&C systems. Review
