Chemical Processing and Production of {sup 99}Mo at Sandia National Laboratories
Sandia National Laboratories (SNL) has recently completed the irradiation of five isotope production targets at its Annular Core Research Reactor (ACRR) using targets fabricated by Los Alamos National Laboratory. Four of the irradiated targets were chemically processed in the SNL Hot Cell Facility (HCF) using the Cintichem process. The Cintichem method for processing {sup 99}Mo isotope production targets involves dissolution of a UO{sub 2} coating, separation of the Mo from the other fission products, and purifying the final product. Several processing issues were addressed during the initial process verification work. This paper discusses the results of work involving dissolving the UO{sub 2} coating, recovering Mo losses in purification columns, and radiation exposure testing of process glassware and components.
