PURPOSE: To easily handle radioactive drain enriched liquid as solid waste by transporting the radioactive drain enriched liquid enriched by an enrichment plant to an incinerator and incinerating it after it is impregnated in water absorption resin and gelatinized. CONSTITUTION: Radioactive washing drain enriched liquid of a nuclear power station or the like produced from a waste evaporator 1 as an enrichment plant is impregnated in water absorption resin 2 and gelatinized. A drum can 3 is filled with such gelatinized enriched liquid, transported to an incinerator 5, and incineration and volume reduction are performed. The radioactive washing drain enriched liquid of about 20g is absorbed in the water absorption resin 2 of 1g and gelatinized. When it is incinerated, the volume reduction of 95% can be achieved. Thereby the drum can 3 is filled with the solid waste, which can be easily handled. In addition, when the enriched liquid-impregnate water absorption resin 2 is incinerated in the incinerator 5, less liquid scattering occurs for gelatinization of the enriched liquid and damage caused by heat impact of a furnace wall or the like of the incinerator 5 can be prevented.
