o safety. The regulatory guides Rev. 4 — June 1997 SRP 7.1-4 and the endorsed industry codes and standards are the guidelines used as a basis for the evaluation of conformance to the requirements of the NRC's regulations. Table 7-1, "Acceptance Criteria and Guidelines for Instrumentation and Control Systems Important to Safety," lists the acceptance criteria and guidelines applicable to I&C systems important to safety which are included in the evaluation of these systems as addressed in Chapter 7 of the SAR. Three Mile Island (TMI) Action Plan requirements for I&C systems important to safety are also identified in Table 7-1. Appendix 7.1-A describes the general process for reviewing any I&C system against the acceptance criteria and guidance identified in Table 7-1. The IEEE superseded ANSI/IEEE Std 279 with IEEE Std 603 "Criteria for Safety Systems for Nuclear Power Generating Stations." The requirements and recommendations of IEEE Std 603, as endorsed by Reg. Guide 1.153 "Criteria for Power, Instrumentation, and Control Portions of Safety Systems," incorporate the requirements and recommendations of ANSI/IEEE Std 279. The guidance described in IEEE Std 603 will be used by the NRC staff in its evaluation of the design, reliability, qualification, and testability of the power, I&C, and control portions of safety systems. The scope of IEEE Std 603 includes all I&C safety systems, which are the systems covered in Sections 7.2 through 7.6 of the safety analysis report (SAR). Therefore, while the guidance of IEEE Std 603 and the requirements of ANSI/IEEE Std 279 are equally applicable to protection systems, IEEE Std 603 is more directly applicable to I&C safety systems other than the protection systems (i.e., information systems, safe shutdown systems, and interlock systems). The guidance of IEEE Std 603 is also more readily adaptable for use in the review of non-safety I&C systems. Non-safety I&C systems are reviewed to ensure that they conform to the acceptance
