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.

To investigate tritium extraction technology for the helium-cooled molten lithium test blanket module, a tritium extraction method in the liquid breeder based on the gas-liquid contactor concept has been studied. Preliminary experimental investigations have been designed and prepared at Korea Atomic Energy Research Institute to develop a measurement of tritium concentration and correlation of bubble diameter for stripping gases in the liquid breeder. An acryl vessel and a stainless chamber were manufactured to observe bubble behavior and to measure bubble size, respectively, with a photography method, and the experimental investigations will be performed in the near future. An annular capsule and a plate type made with very thin membrane walls with porous structure inside were developed to improve response time and operational capability for high pressure conditions, and a permeation sensor test device was manufactured to evaluate the proposed permeation sensors. The hydrogen extraction column has been constructed based on the conceptual design for the preliminary investigations, and the fundamental liquid breeding experiments are planned to obtain various experiences on the hydrogen extraction technology.
