The University of Tennessee, in collaboration with the University of California, Davis, Oak Ridge National Laboratory (ORNL), and Pacific Northwest National Laboratory (PNNL), proposes to gain detailed and fundamental understanding of stability of glass waste forms to be used for safe and reliable encapsulation of nuclear waste. The project will seek to understand thermodynamic and structural properties involved in crystallization and phase separation in melt-derived waste form glasses and glass-ceramics by using a baseline glass composition with varying additives. This will be achieved by combining neutron scattering, advanced calorimetric measurements, and extensive modeling study.
