Workshop for Conducting Phase 2 of the INTEC Glass Composition Variation Study

During March 30-31, 1999, the Phase 2 Idaho Nuclear Technology and Engineering Center (INTEC) Glass Composition Variation Study Workshop was held at the Shilo Inn in Idaho Falls, Idaho. The workshop had the purpose of establishing a preparation and characterization protocol for the phase 2b glasses of the INTEC composition variation study. The workshop also had the purpose of reviewing the most recent estimates of INTEC high-level waste compositions for their impacts on the vitrification of these wastes. Waste composition estimates discussed included those of the various calcine types and of the high activity waste fractions from the calcine dissolution/separations process. Persons from the Idaho National Engineering and Environmental Laboratory, Pacific Northwest Laboratories, and Savannah River Technology Center participated in this workshop. As a result of the workshop, details for the preparation and characterization of the phase 2b matrix of glasses were completed. The impac ts on vitrification of updated waste composition estimates were discussed. Actions for the preparation and characterization of the glasses and development of the separations flowsheet were established.
