Abstract

The Enhanced Bayesian THERP (Technique for Human Reliability Analysis) method has been successfully used in real PSA-studies at Finnish and Swedish NPPs. The method offers a systematic approach to qualitatively and quantitatively analyze operator actions. In order to better know its characteristics from a more international perspective, it has been subject to evaluation within the framework of the ‘‘HRA Methods Empirical Study Using Simulator Data.’’ This paper gives a brief overview of the method with major findings from the evaluation work including identified strengths and potential weaknesses of the method. A number of possible improvement areas have been identified and will be considered in future development of the method
