compliance with IEEE Std 603, "IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations," as modified and supplemented by the regulatory guide, is considered by the NRC staff to satisfy the provisions of ANSI/IEEE Std 279. Section 7.1, Table 7-1, and Appendix 7.1-A list standards, regulatory guides, and branch technical positions that provide information, recommendations, and guidance that describe a basis acceptable to the NRC staff. This basis may be used to implement the relevant requirements of the NRC regulations identified above. III. Review Procedures Section 7.1 describes the general procedures to be followed in reviewing any instrumentation and control system. This part of Section 7.2 highlights specific topics that should be emphasized in the RTS review. The review should include an evaluation of the protection system design against the requirements of ANSI/IEEE Std 279, or Reg. Guide 1.153, which endorses IEEE Std 603, depending upon the applicant/licensee's commitment regarding 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 only those design requirements that are specific in nature. For example, paragraph 4.9 of ANSI/IEEE Std 279 requires that the design include the means for checking the availability of each system Rev. 4 — June 1997 SRP 7.2-4 input sensor during operation. Appendix 7.1-B outlines a procedure that can be used to determine whether or not this requirement is met. Appendices 7.1-B and 7.1-C discuss the requirements of ANSI/IEEE Std 279 and IEEE Std 603, and how they are used in the review of the RTS. Although the primary emphasis is on the equipment comprising the RTS, the reviewer must consider the overall protective functions on a system level. The RTS design should be compatible with the accident analysis. It is not sufficient to judge the adequacy of the RTS only on the basis of the
