A Nuclear Reactor Alarm Display System Utilizing AI Techniques for Alarm Filtering

Abstract

A control room upgrade is currently being performed at the Advanced Test Reactor (ATR) at the Idaho National Engineering Laboratory (INEL). As part of the control room upgrade, an improved alarm monitoring and display system is being installed. This system consists of completely redundant termination boards, sequential events recorders (SERs), and fiber optic serial alarm transmission from the SERs to the window panels and to “host” computers. Residing on these host computers will be knowledge-based alarm filtering systems that will pass filtered and prioritized information on to several CRT displays. Further processing will be performed at the display workstations to provide the most effective display to the operators.
