Development of Nuclear Safety Culture evaluation method for an operation team based on the probabilistic approach

According to the validation results, a positive relationship between 'success' states of safety culture and human performance was found, the safety culture state probability profile of each team represents the team characteristic, and the cut-set analysis of the proposed method provides not only the root causes but also the latent causes of failure. Pro-SCHEMe showed possibility to apply NSC to NPP system safety analysis judging by the results of the case study. Further case studies will be conducted to meet the statistical requirement of the results.
