tem. Also reactivity control system interlocks identified in 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 — 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 ANSI/IEEE Std 279 and IEEE Std 603. Appendix 7.1-B item 1 and Appendix 7.1-C item 4 provide review guidance for this topic. The evaluation of conformance with this requirement should be addressed in the review of Section 7.2 of the SAR. l. Criterion 29 — Protection Against Anticipated Operational Occurrences "The protection and reactivity control systems shall be designed to assure an extremely high probability of accomplishing their safety functions in the event of anticipated operational occurrences." Applicability — The protection systems, reactivity control functions of control systems, and supporting data communication systems. Review Methods — Evaluation with respect to the requirements of GDC 29 is based upon conformance of the protection system and reactivity control systems to the applicable GDCs discussed in Sections a through k above. Probabilistic reliability assessments may be performed by the NRC staff to provide a basis for development of deterministic criteria for specific systems. The review of these systems will address conformance to the deterministic criteria so established. Conformance of the reactivity control systems to GDC 29 is addressed in the review of Section 7.2 of the SAR. Rev. 4 — June 1997 SRP 7.1-A-20 3.
