Over 50 million gallons of legacy nuclear waste from WWII need to be contained in a stable form. The preferred approach to prevent contamination of the environment and local communities is turning the waste into glass, or vitrification. Glass is an interesting material with properties (such as color, how it flows, density, and others) that are controlled by its chemistry and processing. Work is on-going at PNNL and around the world to understand how we can optimize glass chemistry to solve real world problems! This presentation will describe why glass is an ideal approach for trapping nuclear waste.

Charmayne Lonergan is a Glass Scientist at the Pacific Northwest National Laboratory in Richland, WA. She is in the Radiological Materials Group in the Energy and Environment Directorate. Charmayne currently works on glass formulations for waste vitrification in support of the Hanford Waste Treatment and Immobilization Plant mission. Her work includes processing novel glass compositions and analysis of their properties, modeling of glass properties, understanding the corrosion behavior of glass waste forms, and development of constraints for glass development. Additionally, she participates in STEM outreach and various professional societies.
