Abstract

To apply the fluoride volatility process to the spent nuclear fuel, fluorination of UO₂ by fluorine has been studied. In this reaction, it is possible that the U-O-F compounds, such as UO₂F₂, are produced. Therefore, study of such compounds is useful in order to know the fluorination behavior of UO₂. This paper presents the fluorination behavior of UO₂F₂ in the presence of F₂ and O₂, analyzed by thermogravimetry and differential thermal analysis (TG-DTA) method using anti-corrosion type differential thermobalance. In fluorine gas, exothermic peaks appeared and volatilization of UF₆. In oxygen gas, only slowly pace decomposition was measured from UO ₂F₂ to UF₆ and UO₃.
