cord and readout in the control room: (A) containment pressure, (B) containment water level, (C) containment hydrogen concentration, (D) containment radiation intensity (high level), and (E) noble gas effluents at all potential, accident release points. Provide for continuous sampling of radioactive iodines and particulates in gaseous effluents from all potential accident release points, and for onsite capability to analyze and measure these samples." Applicability — Information systems important to safety. Review Methods — The accident monitoring instrumentation functions required by 10 CFR 50.34(f)(2)(xvii) should be included in the information systems important to safety and reviewed in accordance with the review guidance provided in SAR Section 7.5. The evaluation of conformance with this requirement should be addressed in the review of Section 7.5 of the SAR. Rev. 4 — June 1997 SRP 7.1-A-4 f. 50.34(f)(2)(xviii) [TMI Action Plan Item II.F.2] Instrumentation for the Detection of Inadequate Core Cooling "Provide instruments that provide in the control room an unambiguous indication of inadequate core cooling, such as primary coolant saturation meters in PWRs, and a suitable combination of signals from indicators of coolant level in the reactor vessel and in-core thermocouples in PWRs and BWRs." Applicability — Information systems important to safety Review Methods — Inadequate core cooling instrumentation functions should be included in the information systems important to safety and reviewed in accordance with the review guidance provided in SRP Section 7.5. Inadequate core cooling instrumentation should provide unambiguous indication of these conditions. It should provide the operator with sufficient information during accident situations to take planned manual actions, and to determine whether safety systems are operating properly. In addition, the instrumentation should also provide sufficient data for the operator to be able to evaluate the
