PROCESS AND APPARATUS FOR CONTINUOUS PREPARATION OF URANIUM TETRAFLUORIDE

摘要

PROCESS AND APPARATUS FOR CONTINUOUS PREPARATION OF URANIUM TETRAFLUORIDE There is provided a process for continuous preparation of uranium tetrafluoride which comprises the steps of continuously feeding uranous solution and hydrofluoric acid into the lower section of a reaction vessel to produce crystal particles of uranium tetrafluoride, floating up and suspending the crystal particles into the upper section of the reaction vessel by the action of agitation to grow up the crystal particles, and then precipitating and discharging the thus grown up crystal particles from the bottom of the vessel, while overflowing a waste solution from the top of the vessel. There is also provided an apparatus to accomplish the aforementioned process.
