A real-time diagnostic system for the EBR-II steam plant has been developed using the DISYS Diagnostic and Control Guidance Expert System. Diagnostic rules were developed to distinctly identify ten specific fault conditions and were tested using a real-time distributed simulation of the EBR-II steam plant. The distributed simulation is implemented in three separate programs in a VAX cluster and is coordinated through a distributed simulation manager operating in a UNIX workstation. The multi-program DISYS system currently operates in the same UNIX workstation as the simulation manager and obtains the simulated data from a shared memory segment maintained by the simulation manager. Future work includes modifying the DISYS system to improve the fault detection of rapid transients and enable it to detect gradual long term trends.
