A Production-Rule Analysis System for Nuclear Plant Monitoring and Emergency Response Applications

A Production-Rule Analysis System for Nuclear Power Plant Monitoring is presented. The signals generated by the Zion-1 Plant are considered for Emergency Response applications. The integrity of the Plant Radiation, the Reactor Coolant, the Fuel Clad, and the Containment Systems, is monitored. Representation of the system is in the form of a goal-tree generating a Knowledge-Base searched by an Inference Engine functioning in the forward-chaining mode. The Goal-tree is built from Fault-Trees based on plant operational information. The system is implemented on a VAX-8500 and is programmed in 0PS-5.
