t the RTS conforms to the design bases requirements of [ANSI/IEEE Std 279 OR IEEE Std 603] and 10 CFR 50.34(f). The RTS conforms to the guidance of Draft Reg. Guide DG-1045. 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 Reg. Guide 1.22 and Reg. Guide 1.118. The bypassed and inoperable status indication conforms to the guidelines of Reg. Guide 1.47. The RTS conforms to the guidelines on the application of the single-failure criterion in ANSI/IEEE Std 379 as supplemented by Reg. Guide 1.53. Based on the review, the Staff concludes that the RTS satisfies the requirement of [ANSI/IEEE Std 279 OR IEEE Std 603] with regard to the system Rev. 4 — June 1997 SRP 7.2-6 reliability and testability. Therefore the Staff finds that the RTS satisfies these requirements of GDC 21. The RTS conforms to the guidelines in Reg. Guide 1.75 for the protection system independence. Based on the review, the Staff concludes that the RTS satisfies the requirement of ANSI/IEEE Std 279 or IEEE Std 603 with regard to the systems independence. Therefore, the Staff finds that the RTS satisfies the requirements of GDC 22. Based on the review of the failure modes and effects analysis for the RTS, the Staff concludes that the system is designed to fail into a safe mode if conditions such as disconnection of the system, loss of energy, or postulated adverse environment are experienced. Therefore, the Staff finds that the RTS satisfies the requirements of GDC 23. Based on the review of the interfaces between the RTS and plant operating
