| 目的 研究低浓六氟化铀运输容器(UX-30/30B运输容器)在夏季进行铁路运输的安全性。方法 分析国内外法规标准，分析容器材料性质，并利用法国达索公司开发的大型有限元分析软件Abaqus对不同工况进行热工分析，综合评价高温对运输安全的影响。结果 运输容器设计批准书规定的“–40~38 ℃”为大气环境温度，而非封闭车厢内的温度;70 ℃在六氟化铀运输容器主要材料的设计温度范围内，对容器性能影响甚微;在国内铁路网运输时，UX-30/30B运输容器可在70 ℃的封闭车厢内安全运输24 h;而在运输容器初始温度38 ℃、每天车厢内持续8 h 70 ℃高温的情况下运输10 d后，运输容器内六氟化铀平均温度最高为49.66 ℃，在海拔高度低于3 141 m时可满足安全运输的要求。结论 低浓六氟化铀运输容器UX-30/30B可安全地在夏季进行铁路运输。 |
| 英文摘要: |
| The work aims to ensure the safety of low enriched Uranium Hexafluoride (UF6) transport container UX-30/30B for railway transportation in summer. National and international regulations and standards as well as the material nature of the container were analyzed. Abaqus, large-scale finite element analysis software developed by Dassault Company was used to conduct thermal analysis on different working conditions to evaluate the effects of high temperature on transportation safety. –40-38 ℃ certificate referred to the ambient temperature of the atmosphere, not the temperature inside the closed carriages; 70 ℃ was within the design temperature range of the main materials of the uranium hexafluoride transport packaging and had few effects on the container performance. The package could be safely transported in a closed carriage at 70 ℃ for 24 h when transported in China's railway network; After 10 d of transportation in the case of initial temperature of 38 ℃ in the transportation container as well as the temperature in the carriage of 70 ℃ for 8 h every day, the maximum average temperature of uranium hexafluoride in the transport container was 49.66 ℃, which could meet the requirements of safe transportation at altitudes lower than 3 141 m. To sum up, low enriched uranium hexafluoride transport containers UX-30/30B are safe for railway transportation in summer. |
