【摘要】 高放废物地质处置容器是高放废物地质处置多重屏障之一,高放废物地质处置容器材料的腐蚀性能决定了处置容器有效性。本文介绍了高放废物容器材料选择的两种策略,以及在不同处置环境下适合的材料,并给出了高放废物地质处置条件下容器材料可能的腐蚀类型。同时介绍了预测高放废物地质处置容器材料寿命的方法和思路,为我国在高放废物地质处置容器的选材上提供新思路和参数。更多还原

【Abstract】 High-level radioactive waste( HLW) geological disposal container is a constituent part of the multi-barrier concept. The effectiveness of the disposal container is determined by the corrosiveness of its material. This paper introduces two methods in selecting container materials, materials which are considered adaptive to certain geological environments as well as potential corrosion types in HLW geological disposal. Also it summarizes approaches to predict the lifetime of HLW disposal containers.更多还原
