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.

A scaling method is proposed for the design of a reduced-scale experimental facility for testing the performance of a newly proposed filtered containment venting system (FCVS). A full-height facility at prototypic pressure and temperature conditions is chosen to preserve the fundamental physics such as depressurization rate, two-phase mixture level, and scrubbing process. The geometrical similarities in terms of the ratio of the cross-sectional area and geometric and frictional loss coefficient are preserved for each component in the FCVS. Scaling of the number of components in the reduced-scale test facility is suggested using the prototypic components of the FCVS including a venturi scrubber, a cyclone, a metal fiber filter, and a molecular sieve. This approach minimizes scaling distortions. A properly scaled test facility allows testing in a wide range of initial and boundary conditions such that it can predict the full performance of the prototypic FCVS.
