Qualified Indication and Alarm System- PAMI Design

Instrumentation and control systems are designed in full digital system for human interfaces and high reliability. In Shin-Kori 3 and 4, the instrumentation and control systems utilize the standardized platform for both safety system and non-safety system. Qualified Indication and Alarm System. Post Accident Monitoring Instrumentation (QIAS-P) is safety related system that displays the variables for accident monitoring. QIAS-P performs the core condition monitoring of saturation margin calculation, reactor vessel monitoring, and core exit temperature calculation. In addition to the core condition monitoring, it monitors post accident variables. In this paper, the design of QIAS-P is described
