applicable to these systems. Our review has included the identification of those systems and components for the ESFAS and ESF control systems 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. Section 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 GDC 2 and GDC 4. Based on our review we conclude that the ESFAS 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 the operation of ESF and EAS systems consistent with the accident analysis presented in Chapter 15 of the SAR. There- fore, we find that the ESFAS satisfies the requirements of GDC 20. The ESFAS 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 ESFAS conforms to the guidelines on the application of the single failure criterion in IEEE Std 379 as supplemented-by R.G. 1.53. Based on our review, we conclude that the ESFAS meets the criteria of IEEE Std 279 with regards to the system reliability and testability. Therefore, we find that the ESFAS satisfies the requirement of GDC 21. The ESFAS conforms to the guidelines in IEEE Std 384 as supplemented by R.G. 1.75 for the protection system independence. Based on our review, we conclude that the ESFAS satisfies the requirement of IEEE Std 279 with regards to the systems independence. Therefore, we find that the ESFAS satisfies the requirement of GDC 22. 7.3-7
