Authors are conducting the analysis and examination regarding uncertainty factors on fault displacement fragility evaluation. Uncertainties of the location of the action point of fault displacement effects the fragilities of the structures and components, and adds uncertainties to system reliability and initiating event frequencies. Uncertainties of the fault displacement action point and its impact on the core damage frequency have been investigated in this study.
