高含盐量放射性固体废物处理工艺研究

Research on the Treatment Technology of High Salt Content Radioactive Solid Waste

核设施运行产生的浓缩液残渣、泥浆和焚烧灰等低、中水平放射性废物属于离散性废物,必须进行稳定化处理才能够送到放射性废物处置场进行最终处置,通常采用水泥固化或装入高完整性容器(HIC)两种处理方式。本文对水泥固化工艺和混凝土HIC处理工艺进行了介绍,对废物高含盐量对水泥固化工艺、混凝土HIC工艺及废物包的处置安全性的影响进行了对比分析。

Low-and medium-level radioactive wastes such as concentrate residue,mud and incineration ash generated by the operation of nuclear facilities belong to discrete wastes,which must be stabilized before being sent to the radioactive waste disposal site for final disposal.Usually using cement solidification or loading into a high integrity container.In this paper,the cement solidification process and concrete HIC treatment process are introduced and compared.The effect of high salt content on the solidification process,concrete HIC process and waste package disposal safety was expounded.
