Abstract 1. A PROCESS FOR THE CONVERSION OF URANIUM HEXAFLUORIDE TO URANIUM DIOXIDE WHICH COMPRISES INJECTING URANIUM HEXAFLUORIDE VAPOR INTO AN UPPER END OF A PROCESS VESSEL COMPRISING AN INCLINED ROTARY BARREL TYPE KILN, REACTING SAID URANIUM HEXAFLUORIDE VAPOR IN SAID UPPER END WITH DRY STEAM TO FORM A PLUME OF URANYL FLUORIDE POWDER, SAID PLUME BEING DIRECTED TOWARDS THE UPPER END OF THE BARREL OF THE LILN SO THAT THE MAJORITY OF THE URANYL FLUORIDE PRODUCED IS DEPOSITED DIRECTLY IN THE UPPER END OF THE BARREL OF THE KILN AND CONVERTING URANYL FLUORIDE POWDER TO URANIUM OXIDE POWDER BY REACTING THE URANYL FLUORIDE PASSING DOWN THE BARREL OF THE KILN WITH A REACTANT SELECTED FROM THE GROUP CONSISTING OF STEAM, HYDROGEN AND A STEAM/HYDROGEN MIXTURE, SAID REACTANT PASSING IN COUNTERCURRENT FLOW TO THE URANYL FLUORIDE, AT A TEMPERATURE HIGHER THAN THE TEMPERATURE IN SAID UPPER END AND SUFFICIENT TO CONVERT SAID URANYL FLUORIDE POWDER TO URANIUM DIOXIDE.
