| Abstract Scope |
The evolution of commercial reactor fuel forms and development of the next generations of reactors spark a demand to close existing data gaps in the performance of advanced reactor fuel concepts. Commercial fuel vendors are targeting higher uranium density fuels to enhance fuel economy and better accommodate accident tolerant cladding, and the leading designs for small modular reactors are looking toward particle fuel architectures. A number of data gaps and/or inconsistencies exist for these lesser known fuel concepts, including their performance during off-normal events involving oxidant ingress. Presented is the utilization of thermal analysis in precision engineered atmospheres to probe the stability of high uranium density and particle fuel forms during high temperature transients. In each of the studies presented, a combination of thermogravimetric, differential thermal, and evolved gas analysis are employed in a dynamic measurement of the response of advanced nuclear materials to accident conditions and atmospheres. |
