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 novel configuration of a photon recycling probe laser system for Thomson scattering (TS) system is proposed to measure electron temperature and density of the divertor region in GAMMA10 by using a polarization control multi-pass technique. This configuration can use for simultaneous measurements of the multi-pass TS measurement of the central plasma and the 1 pass measurement of the divertor plasma. To confirm the feasibility of the new method, we have installed double pass TS system in the GAMMA 10 central plasma. As the result, the scattering light intensity at the second pass has maintained more than 95% of first pass signal. By using a same solid angle and a scattering volume of the GAMMA10 central TS system, electron density of 2×1018 m-3 will be measured at the divertor region.
