乏燃料干法贮存容器屏蔽性能研究

Research on Shielding Performance of Dry Storage Cask for Spent Fuels

乏燃料干法贮存容器的屏蔽设计是关系到乏燃料干法贮存设施辐射安全的重要影响因素。以我国自主研发的乏燃料干法贮存容器为对象,重点围绕屏蔽性能目标的合理确定、屏蔽计算方法、计算假设的选择以及计算结果的分析等多方面展开研究。计算分析表明,自主研发的的乏燃料干法贮存容器的屏蔽性能良好,满足辐射安全要求。

The radiation shielding design of spent fuel storage containers is one of the important factors affecting the radiation safety of spent fuel dry storage facilities.Taking the dry storage container independently researched and developed by China as an example,the paper focuses on the reasonable determination of the shielding performance target,the shielding calculation method,the selection of the calculation hypothesis and the analysis of the calculation results.The calculation analysis shows that the designed spent fuel dry storage container is with good shielding performance and meets the radiation safety requirements.
