In summary, this paper describes the simplified process by which wastes are qualified, how formulations are verified, and how wastes are processed by the GTF and its support facilities for permanent isolation and disposal. Grout treatment involves mixing the low-level fraction of DST wastes with cementitious solids and chemical additives as necessary. The resulting grout slurry is pumped into reinforced concrete vaults located at the near-surface disposal site to cure and solidify. The DST waste is disposed of in batch sizes of approximately 3800 m/sup 3/, which is the capacity of the grout feed tank. When the dry solids have been mixed with the liquid waste, the total grout volume is approximately 5300 m/sup 3/. The disposal of large monoliths was selected to reduce personnel exposure to radioactive materials and to enhance long-term performance of the final waste form. 3 figs.
