Material Balance Assessment for Double-Shell Tank Waste Pipeline Transfer

摘要

The objective of this study was to develop a material balance calculation methodology for variable waste properties and tank conditions to detect waste leaking and misroutings during the double-shell tank (DST) waste pipeline transfer between and within the 200 East and 200 West Areas of the U.S. Department of Energy's Hanford Site. Waste will be transferred from a DST either to another DST or to a waste treatment (vitrification) plant storage tank. This methodology is to address a Final Safety Analysis Report's recommendation to be able to perform material balance calculations as a backup method to pit leak detectors.
