Paradigm for Expert Display Systems in Nuclear Plant and Elsewhere

L. Beltracchi has recently published work on a Rankine cycle display of operation for a nuclear power station. Discovery of the display was lengthy and difficult. This paper discusses similar CRT displays of plant operation from the point of view of knowledge representation and presents an abstraction describing a wide class of such displays. It is suggested that this abstraction is a useful tool for discovery of good safety displays. An example for an idealized, very simple plant is given to explain the concept.
