Study on Risk of Nuclear Spent Fuel Marine Transportation

The safety of hazardous materials marine transportation is an important aspect of marine transportation safety. As the seventh category of hazardous materials, spent fuel has strong radioactivity and high decay heat, which makes the marine transportation of spent fuel concerned by the national competent department. Risk analysis is based on the identification of risk factors, through qualitative or quantitative analysis methods, to analyze the possible consequences of these risks and the possibility of these consequences, so as to determine the corresponding risk level and formulate targeted risk control measures. The safety of marine transportation depends not only on the safety of the cargo itself, but also on the navigation safety of the ship. On the basis of introducing the steps and methods of risk analysis, this paper selects various factors affecting the safety of spent fuel marine transportation from the aspects of cargo itself and ship navigation safety, and establishes a scientific and reasonable spent fuel marine transportation safety evaluation index system; The risk factors of maritime transportation are evaluated by risk evaluation methods such as expert scoring and risk coordinate diagram, some measures and suggestions are put forward according to the evaluation results.
