finds that the ESFAS and ESF control design satisfies the requirements of General Design Criteria 13 and 19. Based on the review of system functions, the staff concludes that the ESFAS conform to the requirements of (IEEE Std 279-1971 or IEEE Std 603-1991) and 10 CFR 50.34(f). The ESFAS setpoint methodology conforms to the guidance of RG 1.105, “Setpoints for Safety-Related Instrumentation.” Based upon this review and coordination with those having primary review responsibility for the accident analysis, the staff concludes that the ESFAS includes the provision to sense accident conditions and anticipated operational occurrences consistent with the accident analysis presented in Chapter 15 of the SAR and evaluated in the SER. Therefore, the staff finds that the ESFAS satisfies the requirements of GDC 20. The ESFAS conforms to the guidelines for periodic testing in RG 1.22, “Periodic Testing of Protection System Actuation Functions,” and RG 1.118, “Periodic Testing of Electric Power and Protection Systems.” The bypassed and inoperable status indication conforms to the guidelines of RG 1.47, “Bypassed and Inoperable Status Indication for Nuclear Power Plant Safety Systems.” The ESFAS conforms to the guidelines on the application of the single-failure criterion in IEEE Std 379, “IEEE Standard Application of the Single-Failure Criterion to Nuclear Power Generating Station Safety Systems,” as supplemented by RG 1.53, “Application of the Single-Failure Criterion to Safety Systems.” Based on the review, the staff concludes that the ESFAS 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 ESFAS satisfies these requirements of GDC 21. The ESFAS conforms to the guidelines in RG 1.75, “Criteria for Independence of Electrical Safety Systems,” for the protection system independence. Based on the review, the staff concludes that the ESFAS
