The preferred processes should be developed and finalized on an expedited basis. In addition, the development of the molten salt oxidation process followed by plutonium oxide recovery should be expedited. This process was the only technology identified that had multi-purpose applicability to this treatment problem. Thermal treatment (calcination),

There is an apparent lack of acceptable processes for treating the organic liquids, combustible solids, and polycubes. The molten salt process should be further reviewed for these waste streams. 4. The waste streams should be processed by a strategy that gives priority to major safety concerns first. Thus, the liquids should be treated early followed by the organic solids and low-fired plutonium oxide. The second consideration is the quantity of material needing stabilization, which suggests a need for early processing of the oxides. The priority for early treatment of organic solids is frustrated by the current lack of good, demonstrated technology. . The potential of direct repackaging of the metals and high-fired oxides should be examined. These waste streams represent approximately 40% of the mission need.
