e EAS system are acceptable and meet the relevant require- ments of General Design Criteria 2, 4, 20, 21, 22, 23, 24, and 25 and 10 CFR Part 50, §50.55a(h): We have conducted an audit review of these systems for conformance to guidelines of the regulatory guides and industry codes and standards applicable to these systems. In Section 7.1 of this SER we concluded that the applicant had adequately identified the guidelines applicable to these systems. Based upon our audit review of the system design for conformance to the guidelines we find that there is reasonable assurance that systems conform fully to the guidelines applicable to these systems. Our review has included the identification of those systems and components for the RTS which are designed to survive the effects of earthquakes, other natural phenomena, abnormal environments and missiles. Based upon our review we conclude that the applicant has identified those systems and components consistent'with the design bases for those systems. Sections 3.10 and 3.11 of this SER address the qualification programs to demonstrate the capability of these systems and components to survive these events. Therefore we find that the identification of these systems and components satisfies this aspect of the GDC 2 and 4. Based on our review we conclude that the RTS conforms to the design bases requirements of IEEE Std 279 and that the system includes the provision to sense accident conditions and anticipated operational occurrences to initiate reactor shutdown consistent w'ith the accident analysis presented in Chapter 15 of the SAR. Therefore, we find that the RTS satisfies the requirements of GDC 20. The RTS conforms to the guidelines for periodic testing in Regulatory Guide (R.G.) 1.22 and IEEE Std 338 as supplemented by R.G. 1.118. The bypassed and inoperable status indication-conforms to the guidelines of R.G. 1.47. The RTS conforms to the guidelines on the application of the single failure criterion in IEEE Std 379 as
