JAEA has developed the dynamic PRA methodology in order to overcome the limitaion of conventional PRA that event orders and success/fail of safety enginerring equipment are not taking into account the plant status. Dynamic PRA can couple with the reliability model and thermal-hydraulics simulation. In the presentation, we will introduce the purposes of the development of dynamic PRA methodology and overview of the methodology constructed.
