Defense waste tank storage at the Hanford Site
The defense liquid waste storage facilities at the Hanford Site in southcentral Washington State contain radioactive and hazardous chemical wastes generated by 45 yrs of nuclear fuel reprocessing. Current activities involve technology development for waste minimization, storage, treatment, and disposal. The double-shell tank waste will be retrieved, pretreated and separated into a high-level (HLW), transuranic (TRU), and low-level (LLW) fractions. The HLW and TRU fractions will be vitrified in a glass matrix and shipped to a geologic repository. The LLW fraction will be immobilized in grout and disposed of in a near-surface concrete vault on the Hanford Site. The single-shell tank wastes are being characterized to support technology development to define a final disposal alternative. 8 refs., 6 figs.
