Beschreibung
Zusammenfassung:	PURPOSE: A method is provided to improve the processing efficiency of a cellulose radioactive waste by separating a radioactive waste which is contained in the cellulose radioactive waste. CONSTITUTION: A method(100) includes next steps. A cellulose radioactive waste is separated into a cellulosic material and radioactive substance with a hydrolysis process. The hydrolysis process of the cellulose radioactive waste is executed for 15~20 minutes in the temperature condition of 90~100°C by using 70~80% sulfuric acid solution. A slurry is generated by the chemical reaction between the cellulose radioactive waste and the sulfuric acid solution. The radioactive substance is separated from the slurry with a centrifuge.
