EXTRACTION OF MENTAL MODELS OF OPERATORS ON SAFETY FUNCTIONS OF NUCLEAR POWER PLANTS

摘要

This study proposes the cause-mean analysis to extract the mental model of operators for the conception of plant safety functions. The conception is useful because the intactness of plants are maintained if they are accomplished even in the case such that the anomaly cause and its affection are not fully understood by plant operators. A prototype query system is developed to computerize the cause-mean analysis. This paper also discusses the mental models for several subjects extracted by the query system in the respect of the usage of terms.
