Recovered uranium from the Redox and TBP Plants is concentrated to 100 percent UNH by boiling off water and nitric acid in 224-U Building, and the UNH solution is then calcined or denitrated to UO{sub 3} powder in 18 batch-operated calcination pots, also in 224-U Building. Plans are proceeding now to add to the above denitration capacity by installing two additional batch calcination pots of larger diameter than the present 18 pots (6 ft. rather than 2.5 ft.). At the time of design scoping of the existing batch calcination facilities several years ago it was recognized that potential savings in direct labor and maintenance costs, and other operational advantages, would undoubtedly result from the development of a continuous calcination process. However, no continuous UNH calcination process existed at that time, and the 18 batch pots were installed modeled after similar-sized pots in use by the Mallinckrodt Chemical Company at St. Louis. A program to develop a suitable continuous UNH calcination process and equipment is now in progress with the objective augmenting or replacing the existing batch process in 224-U Building. This document sets forth the savings calculated for complete replacement of the batch pots with a new continuous process.
