Abstract

There is described a process for the production of ceramic fuel pellets which contain fission and/or fertile material in oxidized form, by heating porous green fuel pellets in a reducing atmosphere to a temperature below 2500.degree. C., molding in a die, ejecting from the die and cooling the finished pellets. Thereby the heating and cooling is carried out stepwise whereby the heating and cooling speed below 1200.degree. C. is less than 30.degree. C./second and above 1200.degree. C. is greater than 30.degree. C./second.
