The primary responsibility of the Chemistry R and D group is support of production operations at Rocky Flats. A diverse group of programs and projects is involved in doing this, but a common theme exists in all of these - plutonium, its recovery, purification, and reaction with the environment. Highlights of accomplishments in FY83 include: completing development and demonstration of Molten Salt Extraction using tilt-pour furnaces; completing production demonstration runs for direct oxide reduction of plutonium oxide; completing development work on a preliminary pyrochemical scrub alloy process to extract plutonium and americium from recent (post-1981) Molten Salt Extraction waste salts; completing an evluation of two mechanically agitated contactor designs for a new solvent extraction system being installed in Production for recovery of plutonium from U-Pu solutions; life-testing of a less expensive alternative to wrought tungsten crucibles currently used in production tilt-pour furnaces; completing development of an erbium oxide ceramic coating for protecting stainless steel foundry molds from molten plutonium; using a surface analysis by Auger and ESCA spectrometry to aid in troubleshooting production problems such as characterization of silver films produced with various heat treatment and carbon/oxygen contamination on copper welds.
