icable 7.5-4 Rev. 3 - February 1984 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 information systems which are designed to survive the effects of earthquakes, other natural phenomena, abnormal environ- ments, and missiles. Based upon our review we conclude that the applicant has identified those systems and components consistent with the design basis 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 GDC 2 and GDC 4. The information systems important to safety conform to the guidelines for the instrumentation to access plant conditions during and follow- ing an accident provided in ANSI/ANS-4.5-1980, "Criteria for Accident Monitoring Functions in Light-Water-Cooled Reactors" as supplemented by Regulatory Guide (RG) 1.97. The redundant information systems conform to the guidelines for the physical independence of electrical systems provided in RG 1.75. The instrument spans and set points conform to the guidelines of Regulatory Guide 1.105. The environ- mental monitoring system provided to protect the safety related instrument sensing lines from freezing conforms to the guidelines of RG 1.151, position 5. The safety parameter display system, the infor- mation systems associated with the emergency response facilities and the nuclear data link conform to the guidelines in NUREG-0696, "Func- tional Criteria for Emergency Response Facilities." We conclude that the information systems important to safety include appropriate variables and that their range and accuracy are consistent with the plant
