| Abstract Scope |
Low enriched uranium (U)-10 wt% molybdenum (Mo) is of interest as a monolithic fuel material to replace highly enriched uranium dispersion fuels in high performance nuclear reactors. A proposed manufacturing route for the U- 10wt% Mo fuels begins with casting. Knowledge of the liquidus and solidus phase boundaries is crucial for successful castings in both the design of processing parameters and for predicting the degree of microsegregation. In the current literature, numerous U-Mo phase diagrams are available, but they differ significantly in their definitions of the solid/liquid boundary, specifically on the U-rich side. In an attempt to better define that boundary, an experimental strategy utilizing thermal analysis was employed. The data collected and presented here focuses not on proving a singular point but attempts to provide points with highly characterized uncertainty. |
