Current risk assessment of Spent Nuclear Fuel (SNF) transportation has the problem of the incompleterisk factors consideration and the general particle diffusion model utilization. In this paper, the accidentfrequency calculation and the detailed simulation of the accident consequences are coupled by the integratedrisk assessment method. The “man-machine-environment” three-dimensional comprehensiverisk indicator system is established and quantified to characterize the frequency of the transportationaccidents. Consideration of vegetation, building and turbulence effect, the standard k-ε model is updatedto simulate radioactive consequence of leakage accidents under complex terrain. The developed methodis applied to assess the risk of the leakage accident in the scene of the typical domestic SNF RoadTransportation (SNFRT). The critical risk factors and their impacts on the dispersion of the radionuclideare obtained
