Patent ID: 8829261

Claim:
A method of treating radioactive metal waste generated from nuclear fuel processing facilities or nuclear fuel production facilities using melt decontamination, comprising the steps of: selecting radioactive metal waste according to the shape of metal (S 10 ); classifying the selected radioactive metal waste according to a generation source and a material quality thereof (S 20 ); surface-decontaminating the classified radioactive metal waste according to a radioactivity level thereof (S 30 ); charging the surface-decontaminated radioactive metal waste in a melting furnace (S 40 ); melting the charged radioactive metal waste to form a molten solution and then introducing an impurity remover containing SiO 2 into the molten solution to form slag (S 50 ); removing the slag from the molten solution to obtain an ingot (S 60 ); and forming an ingot obtained by removing the slag from the molten solution (S 70 ).
