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 Hanbit magnetic mirror device, which is operated as a joint plasma research facility, has been constructed at Korea Basic Science Institute for basic study and technology development of high temperature plasma confinement, plasma heating and diagnostics, and plasma applications, such as high-temperature material testing for tokamak divertors. A 500-kW RF transmitter and a 100-kW RF transmitter for ICRF heating are major heating sources in operation, and a few gyrotron-based ECRH systems are in preparation. The target plasma parameters at the central cell are 1-keV ion temperature, 200-eV electron temperature, and 5 × 1012 cm−3 electron density with 500-ms plasma duration. The present status of the Hanbit device, which includes the system overview and recent experimental result, is described in this paper, and future plans will be discussed.
