Abstract

DISYS is a real-time diagnostic and control guidance expert system designed to aid plant operators during off-normal events. Currently it is being implemented and tested at the Experimental Breeder Reactor II. DISYS is driven by sensor input and evaluates symptoms and faults associated with components. Component faults in turn allow an evaluation of sub-system, system and plant faults. The hierarchical model of the plant as used by DISYS also allows information regarding system reconfiguration to be generated in the event of a fault. Current testing at EBR II indicates that DISYS can successfully detect component and system anomalies. A model of the Argon Cooling System has been constructed and currently has about 300 rules. Once the diagnostics system for the ACS has been completed, it is intended to implement DISYS on other reactor systems.
