大亚湾核电站旧导向筒处置方案可行性研究

Feasibility Study on Scheme of Disposing SpentGuide Tubes at Daya Bay Nuclear Power Plant

描述了广东大亚湾核电站旧导向筒处置方案的可行性研究，内容包括：处置方案的比较与选择、混凝土包装箱的结构设计和屏蔽设计、旧导向筒装箱操作的工艺设计、包装箱吊装及运输方案的选择、整个处置过程中涉及到的辐射安全和工业安全的分析评价、以及整个工程的经费概算。结果表明：该旧导向筒处置方案技术上可行，经济上合理。采用此方案，对广东大亚湾核电站旧导向筒进行最终处置，既可节省大量经费，也可为我国对核电站产生的不可压缩的中低水平固体废物进行最终处置积累经验。

This paper describes feasibility study on the scheme of disposing spent guide tubes at Daya Bay nuclear power plant,including scheme selection,packing cask design,disposal operation and technological process,budget estimation and safety evaluation.The research results show that the new scheme is feasible on technology,and reasonable on budget.If the scheme is adopted to dispose the spent guide tubes at Daya Bay nuclear power station,it can not only save large funds,but also accumulate experience on disposing non compressible low and intermediate level solid radioactive wastes produced at nuclear power station for the country.
