ng) 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 accident monitoring instrumentation designed to satisfy RG 1.97 should be identified in the SAR. This includes acceptable deviations and clarifications identified in BTP 7-10. 1. The review should include an evaluation of the information systems design against the guidance of IEEE Std 603-1991 or IEEE Std 279-1971, depending on the applicant or licensee’s commitment regarding these design criteria. For computer-based information systems important to safety, guidance is provided by IEEE Std 7-4.3.2 as endorsed by RG 1.152. These procedures are detailed in SRP Appendix 7.1-B for IEEE Std 279-1971, SRP Appendix 7.1-C for IEEE Std 603-1991, and SRP Appendix 7.1-D for IEEE Std 7-4.3.2. The reviewer should consider the overall information system functions at the 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 IEEE Std 279-1971 or IEEE Std 603-1991. 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 accident monitoring instrumentation, ERF, and SPDS. The information systems review should address the topics identified as applicable in SRP Table 7-1. SRP Appendix 7.1-A describes review methods for each topic. Certain guidance documents identified in Parts 3 and 4 of SRP Table 7-1 apply only to BISI or accident monitoring instrumentation, but not both. The guidance documents that are applicable to specific systems are identified below. Major design considerations that should be emphasized in the review of the information systems important to safety are identified below. Recommended review emphasis for accident monitoring instrumentation A.
