In the present study the rotary reactor used for producing UO2 from AUC is modeled. For this purpose, the governing equations, including mass and energy balance equations for the existing species and phases are derived based on the conservation laws and then they were solved numerically. All other required parameters for solving the governing equations, including the geometrical characteristics of the solid bed, hydrodynamic conditions of the bed and reactor, thermo-physical properties of gaseous and solid species and existing reactions were obtained from the literature and were used. Individual reaction kinetics, presented in the literature for the reactions which are taking place in this reactor, shows many shortages for condition in which all the reactions are taking into account simultaneously. Thus, for the first time, a new kinetics model is proposed and is applied successfuly. The results of using the model are in good agreement with the logical and expected behavior which can be obtained based on the principles of chemical engineering science.
