PLANT FOR PREPARATION OF URANIUM DIOXIDE POWDER BY MEANS OF PYROHYDROLYSIS METHOD FROM URANIUM HEXAFLUORIDE

摘要

A plant for uranium dioxide powder preparation from uranium hexafluoride contains at least one heating reaction chamber with a nozzle for supply therein components of pyrohydrolysis reaction of uranium hexafluoride, means for unloading and transportation of produced uranium dioxide powder and a furnace for post reduction of unreacted uranylfluoride having a discharge chamber with nozzles for supplying hydrogen and aqueous vapor to the furnace. The end part of nozzle for aqueous vapor supply is placed in the furnace retort and is made with closed end face and holes in the side wall.
