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.

In 2016 California made the political decision to prematurely shutter California's remaining nuclear power plant. Diablo Canyon's Units 1 and 2 are now slated for closure in 2024 and 2025 when their current operating licenses expire but, now, Gov. Gavin Newsom is reconsidering the move. This will be a paneled discussion on how Diablo Canyon fits into California's energy and climate strategies, as well as discuss the feasibility and the economic and environmental benefits and costs associated with California's dilemma on whether to keep the facility open beyond 2025 or prematurely close it. Along with discussing decarbonization, industrial process heat and desalination opportunities for Diablo Canyon, as outlined recently in a 2021 joint study by MIT and Stanford researchers, panelists will discuss how the future of Diablo Canyon is vital for California's clean energy security and in advancing the interests of labor, land conservation, and California's aboriginal tribal communities.
