Precipitation and Deposition of Aluminum Containing Species in Tank Wastes
Aluminum-containing phases represent the most prevalent solids that can appear or disappear during the processing of radioactive tank wastes. Processes such as sludge washing and leaching are designed to dissolve Al-containing phases and, thereby, minimize the volume of high-level waste glass required to encapsulate radioactive sludges. Unfortunately, waste-processing steps that include evapora...
متن کاملEvaporation and Storage of Liquid Radioactive Waste
The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...
متن کاملCassava Bran– Fish Processing Waste as Dry Season Feed Resources for Sheep in Nigeria Southern Guinea Savannah
Seasonal variability impact on livestock production and management stems from poor pasture quality and quantity as well as shortage of water. During wet season, there is usually sufficient quantity of pasture in good quality for animal consumption; but during dry season, there is always insufficient pasture as well as shortage of water for livestock consumption. As a result of these, exploratio...
متن کاملModeling of the Savannah River Site High Level Waste
Three evaporators are used to reduce the volume of waste in the waste tank farm at the Savannah River Site (SRS). Evaporators are crucial operation in the SRS waste processing and management system. Using the Aspen Custom Modeler (ACM) software package marketed by Aspen Technology, Inc., the evaporator dynamic flowsheet models have been constructed to simulate the behavior of the evaporator sy...
متن کاملRadionuclide transport Flux Hydraulic conductivity Radioactive waste Vadose zone Sensitivity analysis RETENTION: Permanent Sensitivity Analysis for I-129 Wastes: Effect of Hydraulic Conductivity
Solid low-level radioactive wastes at the Savannah River Site (SRS) are disposed in trenches. In order to determine the permissible radioactive inventory limits for such disposal facilities, it is required to assess the behavior of radioactive waste material over long periods of time. The sensitivity of flow and I-129 (and similar radionuclides) transport in groundwater in the vadose zone to th...
