基于CFD的放射性废物运输容器热工分析

Heat Transfer Simulation of Adioactive Waste Transport Container Based on CFD

摘要: 高密度聚乙烯高整体容器(HDPE-HIC)屏蔽运输容器的开发，需要满足《放射性物品安全运输规程》(GB 11806-2019)的要求，进行热工计算分析。本文对HDPE-HIC的屏蔽运输容器建立了三维模型，通过STAR-CCM软件对正常运输工况和事故运输工况屏蔽运输容器的传热特性进行数值模拟分析，得到了屏蔽运输容器的温度分布。结果表明，容器能够保持完好的包容性和屏蔽性，满足GB 11806-2019要求，可为后续验证试验提供支持。

Abstract: The development of high-density polyethylene high integral container (HDPE-HIC) shielded transport container needs to meet the requirements of the “regulations for the safe transport of radioactive material” (GB 11806-2019) and carry out thermal calculation analysis. 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.
