Chemistry research and development. Annual progress report, November 1, 1979-October 31, 1980
Chemistry R and D is involved in a number of programs. These programs include process support to Rocky Flats production operations, development of pyrochemical processes for plutonium recovery and purification in addition to integration of these processes into production, actinide separation research, determination of thermodynamic properties of plutonium and plutonium compounds, preparation of special alloys for use in radiochemical tracer programs, development of processes for decontaminating plutonium and plutonium compounds, preparation of special alloys for use in radiochemical tracer programs, development of processes for decontaminating plutonium-contaminated soils, characterization of the surfaces of various metals, and investigating the mechanisms and kinetics of the plutonium-hydrogen-oxygen systems. Some specific highlights for the report period include the following: (1) as part of the ongoing soil decontamination program at Rocky Flats, a site survey was completed in which data on contaminated soils in the United States were assembled and a set of soil contamination criteria was proposed to govern the disposition of effluent soil fractions from a soil decontamination process; (2) a series of disks were prepared for a Radiochemical Diagnostic Tracer Program from plutonium-242 and from an alloy of cerium and americium-241; (3) a material balance around past and current americium recovery processes was completed; (4) the technical feasibility of the pyroredox process was established for purification of plutonium in a tilt-pour furnace; and (5) in the continuing investigation of the plutonium-hydrogen system, it was shown that the kinetics of the hydriding of plutonium in a powder form is proportional to the hydrogen pressure below a pressure of 1000 Pa and is independent of the hydrogen pressure above 1000 Pa.
