Study on classification of safety-related organizational factors in a nuclear power plant

On the basis of the existed classification system of organizational factors, questionnaire and event analysis, a more comprehensive classification scheme is developed. The main framework is composed of target and strategy, organizational structure and organizational culture. The scheme makes efforts to overcome the deficiencies of the other classification system. On the basis of this classification framework, 71 human factor events between 2000 and 2003 are reanalyzed. Through descriptive statistical analysis, main management deficiencies in connection with organization are identified. On the basis of R-type clustering, main categories of organizational factors are concluded.
