The monolithic mini-plates to be included in the EMPIRE experiment consist of U-10Mo alloy foils coated with Zr as a diffusion barrier and clad with AlFeNi alloy. The Zr is applied by co-rolling and a PVD process. The Al alloy cladding is bonded to the fuel foils using a proprietary technique (C2TWP) that is currently in development and fundamentally different from the Hot Isostatic Press method used for cladding monolithic fuel in the US. It appears that, in the current development stage, the method does not cause sufficient plastic flow to cover the edges of the U-10Mo foil completely resulting in small V-shaped voids (100-200 Ám). Finite element analysis was performed to evaluate potential effect of the V-shaped voids on the thermo-mechanical behavior of the monolithic mini-plate during irradiation. Preliminary results showed relatively higher normal stresses in the vicinity of the voids region compared to mini-plates having perfectly covered edges.
