Small Tank Tetraphenylborate Process Vessel
One of the alternatives to processing the highly radioactive salt solutions in the Savannah River Site's Waste Tanks, is to precipitate the highly radioactive cesium with sodium tetraphenylborate, concentrate, and wash the precipitate slurry. This process is called the Small Tank Tetraphenylborate Precipitation process (STTP). In the STTP process, soluble ions of cesium, potassium and ammonium are precipitated as insoluble tetraphenylborate (TPB) salts. The resulting slurry, which now contains most of the radionuclides as insoluble solids, is filtered to concentrate the solids. After washing the solids to reduce the concentration of soluble sodium salts in the slurry, the precipitate is processed and incorporated into a glass form in the Defense Waste Processing Facility (DWPF).
