em functions, the staff concludes that the RTS conforms to the design bases requirements of [IEEE Std 279-1971 or IEEE Std 603-1991] and 10 CFR 50.34(f). The RTS conforms to the guidance of Regulatory Guide 1.105. Based upon this review and coordination with those having primary review responsibility for the accident analysis, the staff concludes that the RTS includes the provision to sense accident conditions and anticipated operational occurrences in order to initiate reactor shutdown consistent with the accident analysis presented in Chapter 15 of the SAR and evaluated in the SER. Therefore, the staff finds that the RTS satisfies the requirements of GDC 20. The RTS conforms to the guidelines for periodic testing in Regulatory Guide 1.22, “Periodic Testing of Protection System Actuation Functions,” and Regulatory Guide 1.118, “Periodic Testing of Electric Power and Protection Systems.” The bypassed and inoperable status indication conforms to the guidelines of Regulatory Guide 1.47, “Bypassed and Inoperable Status Indication for Nuclear Power Plant Safety Systems.” The RTS conforms to the guidelines on the application of the single-failure criterion in IEEE Std 379-2000, “IEEE Standard Application of the Single-Failure Criterion to Nuclear Power Generating Station Safety Systems,” as supplemented by Regulatory Guide 1.53, “Application of the Single-Failure Criterion to Safety Systems.” Based on the review, the staff concludes that the RTS satisfies the requirement of [IEEE Std 279-1971 or IEEE Std 603-1991] with regard to the system reliability and testability. Therefore the staff finds that the RTS satisfies these requirements of GDC 21. The RTS conforms to the guidelines in Regulatory Guide 1.75, “Criteria for Independence of Electrical Safety Systems,” for the protection system independence. Based on the review, the staff concludes that the RTS satisfies the requirement of [IEEE Std 279-1971 or IEEE Std 603-1991] with regard to the
