Mound Laboratory, in its many years of plutonium processing experience, has recovered over 150 kilograms of plutonium-238. Much of this material has been recovered from HEPA filters and other secondary wastes such as sludge, slag, etc. The basic recovery nitric acid leach process at Mound for the decontamination of HEPA filters will be improved and modified i this project for processing filters from the Nuclear Fuel Cycle. Efforts this past quarter were directed toward determining the dissolution parameters of plutonium in HNO{sub 3} which included a study of the optimum acid concentration and optimum dissolution temperature
