后处理废包壳的特征及去污技术研究

Study on Characteristics and Decontamination Technology of Waste Cladding After Treatment

后处理废包壳产生量大、放射性水平高、去污技术难度大。对废包壳进行去污处理,实现放射性降级/非α化,可显著降低废包壳最终处置的费用及工作人员职业受照剂量。本文总结了后处理废包壳的物理特征、放射性核素分布规律,并对曾经实施或现处于研究阶段的废包壳去污方法,如化学去污、超声波去污、电化学去污等,进行了详细的介绍。

The post-treatment waste cladding has a large amount of production,high radioactivity level and difficult decontamination technology.Decontamination of waste cladding to realize radioactive degradation/non-αcan significantly reduce the cost of final disposal of waste cladding and the occupational exposure dose of workers.In this paper,the physical characteristics and the distribution law of radionuclides of the reprocessing waste cladding are summarized,and the decontamination methods of waste cladding,such as chemical decontamination,ultrasonic decontamination and electrochemical decontamination,which have been implemented or are currently in the research stage,are introduced in detail.
