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 fully exposed center conductor post (CCP) in a spherical tokamak will receive strong neutron irradiation. The analytical results for a CCP in a spherical tokamak reactor are given considering the irradiation effects such as radiation damage, transmutation, nuclear and resistive heat removal, induced radioactivity and blanket tritium breeding ratio, etc. These results are compared with those for the first wall of conventional tokamaks, assuming the same technical requirements.
