| Abstract Scope |
Crystalline ceramic waste forms are excellent candidate hosts for long-term immobilization of nuclear materials. Ceramic materials are typically processed using solid state reaction routes, which present processing challenges and are lacking significant demonstrated application in nuclear waste processing environments. To advance the technology readiness of ceramic waste forms and broaden the available waste disposal options, Savannah River National Laboratory (SRNL) has been exploring melt-cast ceramic waste forms intentionally designed to crystallize upon cooling from a melt. Challenges associated with melt-casting ceramic waste forms and the effects of the resultant microstructure and phase assemblage on the performance and properties of the waste form will be discussed |
