Abstract

The Tank Waste Information Network System (TWINS) comprises many components of software and hardware, as well as procedures, all of which have been designed to facilitate the tasks of managing tank waste data, analyzing the data, preparing reports, and making decisions to safely manage the tank wastes. Over time, tools have been added to provide automation throughout the process of tank characterization and related reporting (1998-2010). TWINS contains a comprehensive set of databases and tools that are being used to characterize the Hanford tank wastes. The purpose of this document is to provide a single source description of TWINS. TWINS consists of a number of primary databases, reporting tools, and support tools, all of which were created to support the characterization or process engineering needs. These database systems consist of Tank Characterization Database (TCD), Tank Vapor Database (TVD), TWINS, the Best Basis Inventory Maintenance (BBIM) tool, the TXFR tools, the Automated Statistics (AUTOSTAT) tool, and the Automated Vector (AUTOVECTOR) creation tool. This suite of software was developed primarily to support the customer organization responsible for characterizing the tank wastes and comprises the TWINS core software.
