Content:
her penetrations that provide a path to the environment should be isolated on a high radiation signal as one of the diverse isolation functions. The review of these design provisions to address 10 CFR 50.34(f)(2)(xiv) should be addressed in the review of Section 7.3 of the SAR and should be coordinated with the organization responsible for the review of containment systems. NUREG-0737 provides additional guidance on conformance with these requirements. (j) 10 CFR 50.34(f)(2)(xix): Addressing [TMI Action Plan Item II.F.3] Instruments for Monitoring Plant Conditions Following Core Damage "Provide instrumentation adequate for monitoring plant conditions following an accident that includes core damage." Applicability - Information systems important to safety. Review Methods - Instrumentation for monitoring plant conditions following core damage should be included in the information systems important to safety. There should be instrumentation of sufficient quantity, range, availability, and reliability to permit adequate monitoring of plant variables and systems during and after an accident. Sufficient information should be provided to the operator for (1) taking planned manual Appendix 7.1-A-8 Revision 5 - March 2007 actions to shut the plant down safely; (2) determining whether the reactor trip, ESF systems, and manually initiated safety-related systems are performing their intended safety functions (i.e., reactivity control, core cooling, and maintaining reactor containment system and containment integrity); and (3) determining the potential for causing a gross breach of the barriers to radioactivity release (i.e., fuel cladding). The evaluation of conformance with this requirement should be addressed in the review of Section 7.5 of the SAR. (k) 10 CFR 50.34(f)(2)(xx): Addressing [TMI Action Plan Item II.G.1] Power for Pressurizer Level Indication and Controls for Pressurizer Relief and Block Valves "Provide power supplies for pressurizer relief valves, block valves,
