Reasoning and knowledge of nuclear power plant operators in case of accidents.
This paper presents the results of an ergonomics analysis of the work activities of nuclear power plant operators. It focuses on cognitive activity during simulated accidents. Qualitative aspects of this activity are described, which include operators' knowledge, diagnoses, goals, situation ranking and procedure management. The results show that successful emergency operation depends on a combination of adherence to procedures and specific operator competence.
