highlights specific topics that should be emphasized in the review of information systems important to safety. The systems addressed below may be implemented either as stand alone systems or integrated as part of other systems. If the information systems are not isolated from the protection systems, they should also be evaluated according to the criteria in Section 7.2 or 7.3, as appropriate. Other information systems (for example, plant computer and severe accident monitoring) may be included in the review. The acceptance criteria for such systems depend on the function of the system and the applicable design criteria. Any exceptions or deviations to a post-accident monitoring system designed to satisfy Reg. Guide 1.97 should be identified in the SAR. This includes acceptable deviations and clarifications identified in BTP HICB-10. The review should include an evaluation of the information systems design against the guidance of ANSI/IEEE Std 279, or Reg. Guide 1.153, "Criteria for Power, Instrumentation, and Control Portions of Safety Systems" (which endorses IEEE Std 603, "IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations"), depending upon the applicant/licensee's commitment regarding these design criteria. This procedure is detailed in Appendix 7.1-B for ANSI/IEEE Std 279 and in Appendix 7.1-C for IEEE Std 603. The procedures in Appendices 7.1-B and 7.1-C address specific design requirements. The reviewer should consider the overall information system functions on a system level. The design should be compatible with the SAR Chapter 15 design bases accident analyses, and operating procedures as well as applicable guidance of ANSI/IEEE Std 279 or IEEE Std 603. Rev. 4 — June 1997 SRP 7.5-6 The review should also consider the guidance provided in NUREG-0737, Supplement 1, "Clarification of TMI Action Plan Requirements — Requirements for Emergency Response Capability," with respect to PAM, ERF, and SPDS.
