Abstract:

This report identifies the fluid dynamics and chemical modeling capabilities needed to reduce the risk of pipeline plugging during tank waste transfers at the U.S. Department of Energy Hanford Site and evaluates some of the relevant modeling tools currently in use for waste transfer analysis. Work needs to be performed to address the limitations of the current models. Development of improved waste transport modeling tools with the capability to describe particle and chemical dynamics, to account for flow chemical coupling, and to account for waste-surface interactions is essential to completely and accurately evaluate the risk of plugging for some waste transfers. Such capabilities will also help the site assess cost reduction strategies, develop process control strategies, design transfer piping, and diagnose plugging events. The report reviews the capabilities and limitations of (1) a critical velocity correlation and (2) a chemical equilibrium model in use at Hanford as well as (3) a three-dimensional computational fluid dynamics (CFD) model that was investigated by Mississippi State University in FY 2000 and FY 2001.
