When temporary spent fuel storage pools at nuclear power plants reach their capacity limit, the spentfuel must be moved to an alternative storage facility. However, radioactive materials must be handledand stored carefully to avoid severe consequences to the environment. In this study, the risks of threepotential accident scenarios (i.e., maritime transportation, an aircraft crashing into an interim storagefacility, and on-site transportation) associated with the spent fuel transportation process were analyzedusing a probabilistic approach. For each scenario, the probabilities and the consequences were calculatedseparately to assess the risks: the probabilities were calculated using existing data and statistical models,and the consequences were calculated using computation models. Risk assessment software wasdeveloped to conveniently integrate the three scenarios. The risks were analyzed using the developedsoftware according to the shipment route, building characteristics, and spent fuel handling environment. As a result of the risk analysis with varying accident conditions, transportation and storage strategieswith relatively low risk were developed for regulators and licensees. The focus of this study was the riskassessment methodology; however, the applied model and input data have some uncertainties. Furtherresearch to reduce these uncertainties will improve the accuracy of this model.
