t be reviewed before they can be accepted as a sole basis for approval of a design. They are useful as guidance for identifying the subjects of importance to be considered in the review of the systems important to safety. TMI action plan requirements for instrumentation and control systems important to safety are imposed by 10 CFR 50.34(f) for applications approved after February 16, 1982. For operating reactors that had approved construction permits prior to February 16, 1982, the TMI action plan requirements were imposed by Generic Letters that required conformance with NUREG-0718, "Licensing Requirements for Pending Applications for Construction Permits and Manufacturing License," NUREG-0737, "Clarification of TMI Action Plan Requirements," NUREG-0737, Supplement 1, "Clarification of TMI Action Plan Requirements — Requirements for Emergency Response Capability," and NUREG-0694, "TMI-Related Requirements for New Operating Reactor Licenses." Table 7.1 identifies both the CFR and TMI action plan reference numbers for the TMI action plan requirements relevant to Chapter 7 of the safety analysis report. The Action Plan references are given in brackets under the reference to the equivalent requirement of 10 CFR 50.34(f). Appendix 7.1-A presents specific acceptance criteria for TMI Action Plan items. However, important context information is found in the concepts contained in the referenced reports. * The ANSI/IEEE Std 279 requirement to provide adequate separation between protection and control function (item 4.7.2) applies to all instrumentation and control systems. The requirements for display of bypass and inoperable status indication (item 4.13) also apply to information systems important to safety (Section 7.5). Although not required by NRC regulations, the other criteria of ANSI/IEEE Std 279 and Reg. Guide 1.153 address considerations such as design bases, redundancy, independence, single failures, qualification, bypasses, status indication, and testing that
