IIT B52 Antifoam Impact Upon PBA Hydrolysis Kinetics
One of the alternatives to processing the highly radioactive salt solutions in the SRS Waste Tanks is to precipitate the radioactive cesium with sodium tetraphenylborate and then concentrate and wash the precipitate slurry for subsequent processing in the Defense Waste Processing Facility (DWPF). This alternative salt disposition process is called the Small Tank Tetraphenylborate Precipitation process (STTP). In the STTP precipitation process, soluble ions of cesium, potassium and ammonium are precipitated as insoluble TPB (tetraphenylborate) salts. Strontium, uranium, and plutonium are sorbed on solid monosodium titanate (MST). 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 stored until it can be further processed and incorporated into glass in the DWPF. The decontaminated salt solution or filtrate is transferred to Z Area for processing and disposal as Saltstone.
