paired.” Applicability - All I&C systems. Review Methods – The review of compliance with GDC 24 should address the characteristics listed in the table below. These characteristics are described in IEEE Std 279-1971 and IEEE Std 603-1991, and methods for reviewing them are discussed in SRP Appendix 7.1-B and SRP Appendix 7.1-C (see table below for section). Characteristic Review Guidance SRP Appendix 7.1-B SRP Appendix 7.1-C Single-failure criterion Subsection 4.2 Subsection 5.1 Physical, electrical, and communications independence Subsection 4.6 Subsection 5.6 Control protection interaction Subsection 4.7 Subsections 6.6 and 6.3 Auxiliary features Subsection 4.5 Subsection 5.12 Power sources Subsection 4.5 Section 8 The separation of protection and control systems should be considered in the review of all sections of Chapter 7 of the SAR to confirm that all interfaces between control systems and protection systems have been properly identified and addressed. (n) GDC 25, “Protection System Requirements for Reactivity Control Malfunctions” “The protection system shall be designed to ensure that specified acceptable fuel design limits are not exceeded for any single malfunction of the reactivity control systems, such as accidental withdrawal (not ejection or dropout) of control rods.” Applicability - The RTS and reactivity control system interlocks identified in SAR Chapter 15 as required to ensure that specified acceptable fuel design limits are not exceeded for any single malfunction of the reactivity control systems. Review Methods - The confirmation that the protection system is designed for an appropriate spectrum of reactivity control system malfunctions is addressed in the review of protection system design basis requirements as discussed in IEEE Std 279-1971 and IEEE Std 603-1991. SRP Appendix 7.1-B, Section 3 and SRP Appendix 7.1-C, Section 4 provide review guidance for this topic. The evaluation of conformance to this requirement should be
