Abstract
A method for converting uranium hexafluoride to uranium dioxide includes steps of hydrolysis of UFto uranium oxyfluoride (UOF) in a hydrolysis reactor () by reaction between gaseous UFand dry water vapour injected into the reactor (), and pyrohydrolysis of UOFto UOin a pyrohydrolysis furnace () by reaction of UOFwith dry water vapour and hydrogen gas (H) injected into the furnace (). The hourly mass flowrate of gaseous UFsupplied to the reactor () is between 75 and 130 kg/h, the hourly mass flowrate of dry water vapour supplied to the reactor () for hydrolysis is between 15 and 30 kg/h, and the temperature inside the reactor () is between 150 and 250° C.
