Most domestic and overseas low and intermediate level radioactive wastes are stably solidified using solidification processes that conform to national policies, and it is disposed of at the disposal sites designated by individual countries. The generally used cement and polymer solidification technology mixes solidification agents and waste, and the volume of the solidified waste is greatly increased due to the limited incorporation ratio. If powdered radioactive waste is compressed into high-density pellets of the same size, constant pores are formed between particles, and the infiltration of the polymer will be facilitated, and the bulk density of the waste and the filling rate in the drums can be maximized in the solidification process. This compression method is applied to the powdered and particulate wastes that disposal nonconformity radioactive wastes, e.g. dried powder of radioactive concentrated liquid waste, slurry, sludge, powdered wastes generated in the decommissioning process (crushed concrete, decontamination sludge, etc.) and micro-size contaminates soil that is hard to be decontaminated.
