The present work investigates the effect of homogenization of U-10wt% Mo (U-10Mo) alloys on the interface with the clad material. Microstructure-based finite element models were generated based on the actual microstructures of the U-10Mo in the as-cast condition, homogenized at 800°C for 4 hrs, and homogenized at 800 for 16 hrs. Mechanical properties of every element of the Representative Volume Element (RVE) are assigned based on its molybdenum concentration. A Zirconium (Zr) layer is then added on top of the U-10Mo RVE and compression loading is simulated. Model predictions revealed that the as-cast inhomogeneous microstructure consisting of molybdenum rich and lean regions produces a non-uniform U-10Mo/Clad interface. This interface uniformity improves in the case of the microstructure homogenized at 800°C for 4 hrs and is even more uniform in the case of the microstructure homogenized at 800°C for 16 hrs.
