Technology of uranium tetrafluoride preparation by hydrofluorination of UO2 obtained from ammonium diuranate
Description
A study of preparation of uranium tetrafluoride by hydrofluorination of UO2 using anhydrous HF is described. Uranium dioxide was obtained by thermal decomposition of amonium diuranate to UO3 and its reduction with hydrogen generated by cracking ammonia gas. The main purpose is to acquire experience for the UF4 preparation and its technology and found out the best operation conditions, envisaging the installation of an experimental semi-pilot unit for training and small production
