Development of Glass-based Nuclear Waste forms for Legacy and Future Waste Streams

The management and long-term containment of nuclear waste remain central challenges in ensuring the sustainability of nuclear energy and mitigating its environmental impact. This doctoral research focuses on the development glass-based waste forms designed to immobilize volatile radionuclides and optimize vitrification processes for high-level radioactive waste. By integrating glass chemistry with ceramic phase engineering, this work presents a comprehensive approach to addressing two critical issues: the sequestration of iodine-129 (I-129) from off-gas treatment and the control of crystallization in nuclear waste vitrification.
