Uranium-aluminum alloys with a significant enrichment of uranium with 233 U or 235 U serve as nuclear fuels in research reactors. The quality assurance of this fuel requires, among other things, precise knowledge that all trace metal constituents that affect neutron economy, fuel integrity, and fuel fabriion process parameters are well within the specifiion limits.
1/5/2014· The use of uranium powders and pellets can be problematic due to insufficiently homogeneous mixing of uranium oxide and carbon and due to relatively high level of metal impurities. The internal gelation process, which can produce kernels with low levels of metal contaminants, can homogeneously incorporate fine insoluble particles such as carbon throughout the gel spheres.
