Keywords:Severe accident of FBR/LWR, Nuclear fuel debris, Fluorination, Uranium oxide, Zirconium oxide

We proposed the fluorination treatment technology for the fuel debris generated from the severe accident of FBR and LWR. Fluorination behavior of the UO₂ and ZrO₂ pseudo-binary simulated fuel debris was analyzed by the TG-DTA method in the presence of fluorine.
