FABRICATION OF CERAMIC FUEL ELEMENTS BY SWAGING
Ceramic fuel materials can be simultaneously compacted and clad by swaging to form relatively inexpensive fuel elements. The feasibility of manufacturing ceramic fuel elements by the swaging process will depend principally upon the densities obtainable, the reproducibility of the product, and the irradiation behavior of the fuel assembly. Important variables in the swaging process include the characteristics of thc UO/sub 2/ powder, the composition, wall thickness, and outside diameter of the cladding, and the temperature at which the swaging operation is conducted. Certain UO/sub 2/ powders have been compacted to 89 to 92% of the theoretical-density at room temperature and to 94% of the theoretical density at elevated temperatures. The density of any given type of UO/sub 2/ powder after swaging is reproducible to sintering time 1/2%. (auth)
