Hot Extrusion of UO2 Fuel Elements (Final Report to the United States Atomic Energy Commission for the Period July 1, 1960 through June 30, 1961)
- Nuclear Metals, Inc., Concord, MA (United States)
A hot extrusion technique for stainless steel-clad UO2 fuel elements was developed that demonstrates that UO2 can be extruded in a manner analogous to metals. The process, based on the multi-temperature coextrusion technique previously used for metallic fuel elements, involves the coextrusion of UO2 at 1875°C within the cladding at 760°C. The principles employed, the experiments for process development, process and product description, and fabrication of enriched irradiation specimens are discussed.
