Abstract

<p>Phase equilibria in the ThF<sub>4</sub>-PuF<sub>3</sub> system were measured by differential scanning calorimetry. Samples were encapsulated to prevent leakage during the measurements and to prevent fluoride contamination of the instrument. Formation of intermediate compounds and solid solutions was investigated by X-ray diffraction. A thermodynamic model based on the CALPHAD approach was developed for the measured system. Good fit between measurements and phase equilibria calculated using the model was achieved.</p> / RST/Reactor Physics and Nuclear Materials
