Best-Basis Inventory Template Compositions of Common Tank Waste Layers.

[摘要] The Best-Basis Inventory (BBI) Program is chartered to develop a Best-Basis Inventory (Standard Inventory) of chemicals and radionuclides stored in the 177 underground tanks. These inventories are developed directly from tank sample data or in lieu of sample data, from engineering estimates and the Hanford Defined Waste (HDW) model (Agnew, et al. 19972). One of the primary methods for engineering estimates is to determine the volume of waste layers in a tank and combine these volume estimates with the known compositions of the tank waste layers. These tank waste layer compositions are commonly referred to as waste type templates. The original sample-based waste type template compositions were developed in 1996. These templates only addressed solid wastes (sludges and saltcakes). During subsequent annual updates of the BBI, these compositions were found to be deficient for a variety of reasons. This report documents the derivation of updated waste type templates from tank sample data and HDW model data. Both solid waste type templates and liquid waste type templates have been developed.
