Criteria for Accident Monitoring BTP 7-10-2 Revision 5 - March 2007 Instrumentation for Nuclear Power Generating Stations." IEEE Std. 497-2002 establishes flexible, performance-based criteria for the selection, performance, design, qualification, display, and quality assurance of accident monitoring variables. 1. Regulatory Basis 10 CFR 50.34(f)(2)(xvii) requires in part that instrumentation be provided to measure, record, and read out in the control room: containment pressure, containment water level, containment hydrogen concentration, containment radiation intensity (high-level), and noble gas effluents. 10 CFR 50, Appendix A, General Design Criterion (GDC) 13, "Instrumentation and Control," requires in part that instrumentation be provided to monitor variables and systems over their anticipated ranges for accident conditions, as appropriate, to assure adequate safety. GDC 19, "Control Room," requires in part that a control room be provided from which actions can be taken to maintain the nuclear power unit in a safe condition under accident conditions, including loss-of-coolant accidents. It also requires that equipment, including the necessary instrumentation, be provided at appropriate locations outside the control room and that such equipment have a design capability for prompt, hot shutdown of the reactor. GDC 64, "Monitoring Radioactivity Releases," requires in part that means be provided to monitor (1) the reactor containment atmosphere, (2) spaces containing components for recirculation of loss-of-coolant accident fluid, (3) effluent discharge paths, and (4) the plant environs for radioactivity that may be released from postulated accidents. 2. Relevant Guidance Regulatory Guide 1.97 describes a method acceptable to the NRC staff for providing instrumentation to monitor variables for accident conditions. Plants that obtained an operating license after June 2006 should reference the guidance of Regulatory Guide 1.97, Revision 4. For plants with operating
