高燃耗乏燃料运输容器结构设计研究

摘要

With the continuous increasing of the amount of spent fuel assemblies in China, the high burnup spent fuel transport cask is indispensable.The design requirements, structural characters, function and performance parameters are introduced, and the structural strength which meet the requirements in different conditions are also elaborated in this paper.Through the numerical analysis and the correlative experiments, the structural design is reasonable and the analysis method is certificated, the design can meet the standards of the radioactive material transport.%随着中国压水堆核电站核燃料燃耗不断增加,高燃耗乏燃料运输容器在燃料后端物流中必不可少.本文介绍了高燃耗乏燃料运输容器的结构设计要求、结构特点、功能和性能参数;详细阐述了乏燃料运输容器满足各种工况下的结构强度要求.通过数值分析和相应试验,论证高燃耗乏燃料运输容器结构设计的合理性及结构安全分析方法的正确性,验证该设计能够满足放射性物质运输标准要求.
