shutdown capabilities, including remote shutdown capabilities, are provided in SRP Section 7.4. (i) GDC 20, “Protection System Functions” “The protection system shall be designed (1) to initiate automatically the operation of appropriate systems including the reactivity control systems, to ensure that specified acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences, and (2) to sense accident conditions and to initiate the operation of systems and components important to safety.” Applicability - The protection systems, RTS, and ESFAS. Review Methods – The review of compliance with GDC 20 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 sections). Characteristic Review Guidance SRP Appendix 7.1-B SRP Appendix 7.1-C Design basis requirements Section 3 Section 4 General functional requirements Subsection 4.1 Subsections 5, 6.1, and 7.1 System integrity Subsection 4.5 Subsection 5.5 Setpoints Subsections 3 and 4.15 Subsection 6.8 The evaluation of conformance to this requirement should be addressed in the review of Sections 7.2 and 7.3 of the SAR. (j) GDC 21, “Protection System Reliability and Testability” “The protection system shall be designed for high functional reliability and in- service testability commensurate with the safety functions to be performed. Redundancy and independence designed into the protection system shall be sufficient to ensure that: (1) no single failure results in loss of the protection function, and (2) removal from service of any component or channel does not result in loss of the required minimum redundancy unless the acceptable reliability of operation of the protection system can be otherwise demonstrated. The protection system shall be designed to permit periodic testing of its
