【 摘 要 】

The Best Basis Inventory Maintenance Tool (BBIM) is a computer database application with built-in calculations that model the chemical composition of the Hanford tank wastes in terms of three fundamental parameters: (1) Analyte concentration; (2) Waste density; and (3) Waste volume. Using these parameters, the BBIM is able to calculate for all of the Best-Basis constituents in each of the 177 tanks: (1) Total tank waste inventories; (2) Phase-based inventories; and (3) Phase-based concentrations. Calculations are handled differently depending upon the pedigree or type of the underlying data; for example, the input concentration could be in solid units, such as ''ug/g'' or in liquid units, such as ''ug/mL''. In each of these cases, there would be slight variations to the basic inventory calculation formula (Concentration - Density - Volume). In addition to calculating inventories, the BBIM also documents the source of the underlying data and how the calculations were performed. An enhancement is planned for 1Q00 to account for wastes transferred between tanks. When this is in place, the BBIM will be able to reflect ongoing Tank Farm operations, and will continuously (with a slight lag behind operational activities) maintain the documented best-basis inventory.
