The high uranium loading, indispensable for the LEU conversion, has an effect on the homogeneity of dispersion fuels relating substantial variation in fuel product yields. In this study, atomized U-7Mo powders were coated with pure Al, a matrix material, by PVD to avoid the problems of homogeneity. Varying thicknesses of Al was homogeneously deposited on the surface of U-7Mo particles. Al-deposited powders were directly compacted in various densities of compacts without a blending process. The porosity of compacts was measured by the Archimedes method, and the results compared to those of a general compact.
