PROBLEM TO BE SOLVED: To separate transuranium elements by fixing radionuclides in radioactivated graphite waste generated from nuclear facilities in liquid, solving in liquid, suppressing or preventing generation of radioactive gas and making it coexist in common sediment. SOLUTION: The separation process comprises a liquefacient loading process (S2) for loading liquefacient in radioactivated graphite, a heating/melting process (S4) for heating and melting the radioactivated graphite loaded with the liquefacient, and a water solving process (S5) for melting the heated and molten radioactivated graphite in water.
