高放射性核废料辐射对深地质处置环境和储罐材料危害的研究进展

介绍了高放核废料的主要放射性衰变以及用来实验的辐射设备,分别论述了辐射对于金属储罐近域介质(地下水、膨润土及混凝土缓冲回填材料)的影响以及对储罐材料腐蚀的影响。虽然核废料的辐射性对于缓冲回填材料影响不大,但是地下水发生辐射分解使得储罐近域环境变为氧化环境,同时储罐材料受到辐射影响电化学状态也会发生改变。最后指出了当前研究存在的问题及未来重点研究方向。

Hazards Effects of High-level Radioactive Nuclear Waste Radiation on Deep Geological Disposal Environment and Container Materials

This paper aims to introduce that the main radioactive decay of HLNW and the radiation equipment is used for experiment. The radiation effect on the near-field media (groundwater, bentonite and concrete buffer backfill materials) and the corrosion of container materials are discussed respectively. Although the radiation of nuclear waste has little effect on the buffer backfill materials, the near-field environment of containers become oxidized by the radiation and decomposition of groundwater, and the electrochemical state of the container materials may also change by radiation . Finally, the existing problems and future research directions are pointed out.
