| Abstract Scope |
The next generation of Advanced Reactors (ARs) for nuclear energy production are currently being developed in the United States. Integral to commercialization of AR systems are novel waste form solutions that maintain the requisite performance characteristics and safeguard standards as well as the accepted back-end costs in the range of $1/megawatt-hour. Development is underway to demonstrate a simple, rapid, and scalable process capable of immobilizing multiple waste streams from multiple fuel cycles into a durable cermet waste form. The proposed cermet would comprise a metal matrix (e.g., stainless steel) encapsulating dispersed durable ceramic phases derived from constituent salt (halides); oxide; and carbide/C-14 wastes. Correlation of the measured performance with the phase assemblage and chemistry is needed to design and, ultimately, demonstrate the viability of potential cermet waste forms. The results of chemical durability testing on ceramic phases, alloy phases, and consolidated cermet materials is presented. |
