Abstract

A process for producing ceramic fuel pellets for nuclear reactors containing the fissionable material and/or fertile material in the form of the oxide or carbide by heating to a temperature above 1300.degree. C. the crude molded fuel articles compacted to 30 to 60% of theoretical density at room temperature, molding in a die and ejection from the die wherein the heating, molding and ejection take place in a vacuum and the molding and ejection take place within 3 to 300 milliseconds.
