High-level nuclear wastes have been stored in large underground tanks at the Savannah River Plant. Processing of the wastes for ultimate disposal will begin in 1988. Nuclear wastes will be processed to separate the high-level radioactive fraction from the low-level fraction. The separation will be made in existing waste tanks by a process combining precipitation, adsorption, and filtration. The high-level fraction will be vitrified into borosilicate glass in the Defense Waste Processing Facility (DWPF) for disposal in a federal repository. The low-level fraction (decontaminated salt solution) will be mixed with a cement-fly ash blend. The resulting product, ''saltstone,'' will be disposed of onsite by emplacement in an engineered facility. Waste properties, disposal facility details, and wasteform characteristics will be presented. Results of a field test of contaminant release from saltstone and modeling studies to predict releases will also be described. 14 refs., 2 figs., 4 tabs.
