Design and Safety Analysis of a Kind of UO₂ Pellets Transport Container Available to Purchase

In this paper, a kind of transport container we designed was introduced. This container was designed to transport nuclear fuel pellets in different enrichment of U-235. The weight of this package is about 400kg, including the contents. One protect shell and two sealed border were designed in this container, which can ensure the contents were intact and the package has no criticality risk after transport accidents. During the design and safety analysis process, finite element analysis methods were used to improve the structure and analyze the safety performances of the container. In addition, we will test the safety performances of this container through a series of experiments in the future, including 9m drop (or crush), puncture, fire, water immersion and so on. Now, the calculate results show that this container was fit to the safety requirements in the transport accidents.
