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-α can 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.
