摘　　要：国际公认的安全处置高放废物的方法是建造“多重屏障系统”概念设计的深地质处置库。处置容器作为重要的工程屏障之一,需要满足在设计寿命年限内包容放射性废物并将其与地下水隔离的安全功能要求。这要求处置容器在设计寿命年限内保持完整性,不发生失效,因此合理设计处置容器的形状和厚度至关重要。处置容器材料的性质是影响处置容器形状和厚度设计的重要因素。日本选用碳钢为处置容器材料,并已经完成处置容器样件的试制。由于碳钢也是我国高放废物处置容器的候选材料之一,因此主要调研日本高放废物处置容器的形状和厚度设计思路,分析影响处置容器形状和厚度设计的主要因素,重点关注处置容器厚度设计中的抗压厚度和辐射屏蔽厚度参数的确定,旨在为我国高放废物处置容器的设计提供参考。s:To appropriate deal the high-level radioactive waste with internationally recognized method,deep geological disposal repository with multibarrier system is being planned to construct in China.As one of the most important engineering barriers,the canister should maintain integrity and avoid any deformation to meet the safety functions of containing radioactive waste and isolating it from groundwater over the design lifetime.Therefore,it is crucial to reasonably design the shape and thickness of the canister.The properties of the canister materials are important factors affecting the shape and thickness design of the canister.Carbon steel is one of the candidate materials for high-level waste canister in China.Since Japan has chosen carbon steel as the canister material and has completed the trial production of the canister,this paper mainly systematically introduced the design concept about basic shape and thickness of the canister for high-level radioactive in Japan,and analyzed the key factors that need to be considered in the design of the shape and thickness for the canister.Also,emphasis was placed on the determination of the pressure thickness parameter and radiation shielding thickness parameter to provide guidance for the design of the canister for high-level radioactive in China.
