Development in the Application of Knowledge Base Systems in the Canadian Nuclear Industry
Atomic Energy of Canada Limited (AECL) is a leader in the area of computer monitoring and control of nuclear power plants. The high level of plant computerization in CANDU stations has not only provided benefits in terms of more reliable plant operation but also in terms of improved man-machine interface.
Today, new opportunities for improvements in safety and performance include distributed control systems, data highways and improved operator aids. The most exciting innovation is the development of expert systems aimed at assisting the operator in areas such as: fault management and diagnosis, identification of limiting conditions of operation, assessment of heat sink availability, optimization of on-power fuelling schemes, and computerization of procedures and communication.
The “Operator Companion”, an expert system intended to diagnose plant faults and to advise the operator on appropriate restoring and corrective actions, is a major undertaking which is receiving support within the research and engineering groups of AECL and from McMaster University in Hamilton, Ontario.
