applies to information systems important to safety. The parts applicable to all I&C systems are: • IEEE Std. 603-1991, Clause 5.6.3, "Independence Between Safety Systems and Other Systems," and • IEEE Std. 279-1971, Clause 4.7.2, "Isolation Devices" The parts applicable to information systems important to safety are: • IEEE Std. 603-1991, Clause 5.8.2, "Indication of Bypasses," and • IEEE Std. 279-1971, Clause 4.13, "Indication of Bypasses" Review Methods - SRP Appendix 7.1-C provides guidance for evaluating conformance to the requirements of IEEE Std. 603-1991, including the applicable regulatory guides. SRP Appendix 7.1-B provides similar guidance for evaluating conformance to the requirements of IEEE Std. 279-1971. Appendix 7.1-A-4 Revision 5 - March 2007 (c) 10 CFR 50.55a(h)(3), "Safety Systems" "Applications filed on or after May 13, 1999 for preliminary and final design approvals (10 CFR Part 52, Appendix O), design certifications, and construction permits, operating licenses and combined licenses that do not reference a final design approval or design certification, must meet the requirements for safety systems in IEEE Std. 603-1991, and the correction sheet dated January 30, 1995." Applicability - The I&C safety systems including safety portions of engineered safety feature (ESF) control systems; and supporting data communication systems, safe shutdown systems, information systems, interlock systems, auxiliary supporting features and other auxiliary features, and supporting data communications systems. One part of the IEEE standard also applies to all I&C systems, and one part of the standard applies to information systems important to safety. The part applicable to all I&C systems is: • IEEE Std. 603-1991, Clause 5.6.3, "Independence Between Safety Systems and Other Systems" The part applicable to information systems important to safety is: • IEEE Std. 603-1991, Clause 5.8.2, "Indication of Bypasses" Review Methods - SRP Appendix 7.1-C provides
