Technical assessment of disturbance analysis systems

In December 1978, the Electric Power Research Institute sponsored an international specialists workshop on disturbance analysis systems. Since the Three Mile Island incident, the electric-power industry has been evaluating the use of this type of system as a means to improve the operator-process interface during normal and abnormal modes of nuclear plant operation. The functional requirements, justification, technical descriptions, and operation experience with such systems are summarized on the basis of the workshop presentations. Unresolved problems are identified, and ongoing research and development activities in the United States and Europe are briefly reviewed
