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.

Cyclic voltammetry is one of the most common electroanalytical methods for determining the thermodynamic and electrochemical behavior of a species in the eutectic molten salt. The diffusion coefficient, apparent standard potential, transfer coefficient, equilibrium potential, and other parameters can be determined through this method. This study focused on a development of an interactive reverseengineering method by analyzing available uranium chloride data sets (1 to 10 wt%) in a LiCl-KCl molten salt at 773 K under different scan rates to help improve and provide robustness in detection analysis. A principle method and a computational code have been developed by using electrochemical fundamentals and coupling various variables, such as the diffusion coefficients, formal potentials, and process time duration. In addition, a graphical user interface (GUI) through the commercial software Matlab was created to provide a controllable environment for different users. Results provide plots of current, potential, and concentration of each species as a function of time under various determined conditions. The GUI also displays the reversible and irreversible peaks, in a very short run time (around 2 min), with an adequately selected time interval of approximately 0.08 s and an ability to calculate the concentration of each species (e.g., U4+ and U3+) at any specified conditions.
