The sol-gel microsphere pelletization (SGMP) process is a recent concept of oxide fuel pellet fabrication using sol-gel-derived microspheres for pellet pressing and sintering. The SGMP process is particularly attractive for remote refabrication of highly radiotoxic /sup 233/U- and plutonium-bearing oxide fuel pellets because of the dust-free and free-flowing nature of microspheres. However, the process has not been proven to be successful thus far. In the present study, the external gelation of thorium (EGT) and external gelation of uranium (EGU) processes of Kernforschungsanlage have been modified to produce microspheres suitable for making pellets of high density (greater than or equal to 95% TD) and desirable microstructure using pressing and sintering parameters similar to those used in the conventional powder route. The pellet compositions chosen are ThO/sub 2/-2% UO/sub 2/, ThO/sub 2/-5% CeO/sub 2/, UO/sub 2/-5% CeO/sub 2/, and UO/sub 2/-30% CeO/sub 2/. Cerium has been used for the simulation of plutonium.
