This document consists of an analysis of uranium losses from the Y-12 Plant to the Environment during the period August 1943 to May 1956. It was necessary to estimate most of the losses from operating experience and the few exhaust-gas analysis data which were available. The best known losses were the discards to the sewer which flows into Poplar Creek. The Alpha Process, Beta process, and Product processing were described. From most of the operations the losses were in the form of solutions. The purpose of the Beta cycle was to concentrate the product of the Alpha cycle. The effluents from the various precipitation steps were recovered by solvent extraction. Even though total losses were much lower, it was possible that the dust losses were a somewhat higher percentage of the total losses than Alpha. For Beta Product processing, the Beta product was collected on carbon parts and these were cleaned of the bulk of the material, which was in the form of a loose powder; and the remaining carbon was burned to insure complete recovery. It is estimated that there were dust losses in these dry operations and they may have been a sizeable percentage of the total losses from the system. Losses during normal and depleted assay processing from Buildings 9212, 9206, and 9211 and discards to disposal pits and burial grounds were listed. Tables are included with estimated amounts of uranium losses from the Y-12 Plant to the environment.
