Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

The legacy electromagnetic (EM) pump analysis tool MATRIX has been improved by the addition of a thermal analysis module. Although the module is patterned after the general-purpose Advanced General Electric Network Analyzer (AGENA) code, it is developed from a more fundamental approach to provide a better understanding and control of the thermal analysis of the EM pump. The MATRIX results are verified against the AGENA results and the test data from the 160 m3/min large EM pump tests, which provided a good estimate of the thermal conductance between the lamination and the inner duct wall. Full and good contact between the lamination and the inner duct wall is necessary to keep the copper conductor temperatures low. Parametric studies, as expected, confirmed the correct trend of increasing copper conductor temperatures with increasing frequency. The MATRIX results show that a new proposed insulation material for the future EM pumps is beneficial since it could reduce the copper block temperature by ~20°C. Such analysis can help develop a better EM pump with a more compact design and better insulation material.
