The review methods described in this appendix should be used as appropriate. The review guidance of SRP Appendix 7.1-B or SRP Appendix 7.1-C should also be applied to I&C systems required for operation of ESF systems or their auxiliary supporting features and other auxiliary features. (f) GDC 15, “Reactor Coolant System Design” “The reactor coolant system and associated auxiliary, control, and protection system shall be designed with sufficient margin to ensure that the design conditions of the reactor coolant pressure boundary are not exceeded during any condition of normal operation, including anticipated operational occurrences.” Applicability - I&C protection and control systems. Review Methods – The evaluation of I&C system contributions to the design margin for reactor coolant systems should be a part of the review of the adequacy of I&C protective and control functions. This review is coordinated with the organization responsible for the review of reactor systems. The I&C systems may contribute to reactor coolant system design margin in many ways, for example, by providing better than the minimum required performance, as conservatism in setpoint calculations, or by system features that make the protection or control systems more fault tolerant. Margin may also be credited
