S22: Glasses and Ceramics for Nuclear and Hazardous Waste Treatment



The symposium will focus on the use of glasses, glass-ceramics and ceramics for the treatment of nuclear and hazardous wastes. The renewed interest in nuclear power generation and fuel reprocessing means that the processing, properties and testing of traditional glass and cementitious materials suitable for nuclear waste immobilization need to be expanded to meet the future needs. Additionally, increasing stringent environmental regulations increase the requirements for suitable treatment and stabilization of many hazardous constituents resulting from industrial processes which will increasingly involve glass and ceramic matrices. Topics will include the use of mature immobilization techniques such as vitrification, and the role of cementitious materials in both the stabilization of waste and the structural integrity of wasteforms. Alternative low-temperature wasteforms such as hydroceramics and geopolymers will be also considered as well as high-temperature glass composite materials. The symposium will cover materials technologies for the treatment of nuclear, hazardous and toxic wastes, which includes waste immobilization and encapsulation in inert matrices. New and innovative applications of materials and materials processes and alternative wasteform materials and processing methods will be highlighted. Additional topics include characterization and testing techniques for wasteforms and modeling of their behavior over long timescales. Wasteform performance and accelerated testing to assess durability will be also covered. This symposium is co-sponsored by the ICG–Technical Committee on Nuclear and Hazardous Waste Vitrification, ACerS Nuclear and Environmental Technology Division, ACerS Glass and Optical Materials Division, and the Technical Committee on Nuclear Ceramics of the International Ceramics Federation.
