A process for the fabrication of uranium dioxide-uranium dicarbide microspheres for use as an advanced nuclear fuel is described. The uranium-carbon-oxygen phase diagram was used extensively in applying thermochemical principles to the combined process of uranium carbide synthesis and kernel sintering. A procedure was developed to convert urania plus carbon microspheres produced by a wet-chemical gelation process to a highly dense UO/sub 2/-UC/sub 2/ product. 22 refs.
