Establishment of risk-based accident scenarios using the master logic diagram related to LILW management in the temporary storage facility

Abstract

The initiating event, which is the first step in the establishment of risk-based accident scenarios, was derived by master logic diagram (MLD) method based on the fault tree analysis (FTA), and then the risk-based accident scenarios were developed by the event tree analysis (ETA) through the derived initiating events. The main initiating events led to the arbitrary operational accident: the dropping of a drum and fire were derived from the MLD method. Consequently, based on two main initiating events, four heading events were derived. and then the 12 risk-based accident scenarios concerning the LILW management in the temporary storage facility were finally established by the ETA method.
