Vibratory Compaction and Swaging of Uranium Dioxide to High Density
- North American Aviation, Inc., Canoga Park, CA (United States). Atomics International Div.
Techniques for the fabrication of ceramic fuel elements by vibratory compaction and swaging of powders inside a metal tube were investigated. Vibratory packing of powders containing three particle size fractions resulted in a maximum density of 9 g/cm3, or 82.2% of the theoretical density. It was possible to increase the packed density to 9.9 g/cm3, or approximately 90% of theoretical, by cold swaging, and to 10.5 g/cm3 or more than 95% of theoretical, by warm swaging at 600 °C. Fabrication of spherical UO2 shot was investigated. Shot of the desired particle size ranges was produced with densities ranging from 10.2 to 10.5 g/cm3, or 93 to 96% of theoretical density.
