【Abstract】 Human factor event analysis (HFEA) is important for system reliability assessment, especially for probabilistic risk assessment (PRA) in nuclear power stations. There are two analytic methods, THERP (Technique for Human Error Rate Prediction) and HCR (Human Cognitive Reliability), which are generally used separately in HEFA. These methods have their own features. HCR method is better for determining human errors during diagnosis stage of an accident, whereas THERP provides human event tree model and huge amount of data for determining personnel operational errors. Because there are two phases, i.e. diagnoses and manipulations in a human factor event, it is necessary that the THERP with HCR is integrated into a new HFEA model. This paper introduces the analysis procedure and the report format on this new model, and gives an example in one nuclear power station.更多还原
