In this paper, a three-dimensional model of HDPE-HIC shielded transport vessel is established. STAR-CCM software is used to numerically simulate the heat transfer characteristics of the shielded transport vessel under normal transport conditions and accident transport conditions, and the temperature distribution of the shielded transport vessel is obtained. The results show that the container can maintain its integrity and shielding properties, meet the requirements of “regulations for the safe transport of radioactive material” (GB 11806-2019), and provide support for subsequent verification tests.展开更多

In China, high density polyethylene high integrity container (HDPE-HIC) as a new type of cargo package, there is no special shielded transport container, and a set of shielded transport container for HDPE-HIC is developed to prevent radiation to the outside world during the transfer and transportation of radioactive waste. If the container is damaged in the transportation process, it will cause serious consequences to the outside world, so it is very important to analyze the drop and puncture of the shielded transportation container. In this paper, spaceclaim software is used to establish a three-dimensional model of the shielded transport container, and LS-DYNA software is used to simulate the drop and puncture process, and the maximum deformation and strain of the shielded transport container are obtained. After analysis, the current design can effectively contain the contents.展开更多
