摘要： A method of fabrication of nuclear fuel elements having high impermeability to fission gases and made up of refractory fuel particles dispersed in a carbonaceous matrix, said fuel particles being coated with a mixture of graphite and an organic diluent by means of a pelletizing process. An outer jacket for containing the coated particles is fabricated by shaping a paste formed of graphite powder and a binder, then baking and impregnating the jacket with pyrocarbon in a single operation by heating to a temperature between 850* and 1,100* C. in a gaseous hydrocarbon atmosphere.
