Abstract : The influence of the physical mixture of carbon and uranium trioxide powders on the carbothermal reduction of UO3 has been studied : the texture of the powders mixtures was characterised, and its effect on the reduction into UO2 was shown. Finally, a kinetic modelling of the carbothermal reduction of U3O8 was proposed.

Keywords : Carbothermal reduction UO3 kinetics modelling carbon powders uranium trioxide powders
