In this study, a new concept of the scenario development method to be able to represent the importance of a scenario on geological disposal of HLW in an understandable way was examined with considering the versatility. By the carrying out the scenario development using this method, the information relation to the confidence building such as "the reason why the scenario is important scenario", "the argument which is able to claim completely the safety by the assessment according to the scenario" would be represented in the easy-understand format. Furthermore, the useful information for total performance assessment of geological disposal would be given with the role of each study and the relationship between the studies in the assessment.
