Abstract

Abstract: The paper was aimed at identifying PIFs of operators in nuclear power plants and studying interrelationships between them. A relatively comprehensive and specific classification system of PIFs was built from the perspective of organization after literature survey. Important factors impacting operator's error were identified by analysis of human factor events in nuclear power plants. Correlation analyses between PIFs were carried out based on the sample data on human factor events, relationships between PIFs were studied. The results show that the main factors influencing operators are psychological state, quality and capacity of operators belonging to individual factors, and procedures, training and organizational management belonging to contextual factors etc, and that individual factors are influenced by various contextual factors, but the influencing relationships are diffierent between the contextual factor and various individual factors, for example, human psychological state is mainly influenced by person's quality and ability, technical system and so on, and human physiological state is mainly influenced by work environment, team factors and organizational structure and so on.

Key words: performance influencing factors (PIFs), human error, organizational factors, correlation analysis, nuclear power plants
