Description

A fault location method based on the graph approach is proposed. The method can deal with failure propagation time and failure propagation probability. Several candidates for failure origin are shown in the digraph. The priority ranking among the candidates is evaluated taking into account propagation probability and failure rate. This method is applied to the primary loop recirculation system of boiling water reactors. How effectively failure origin in an abnormally functioning system can be identified through the application of this method is examined. (author)
