Abstract (en)

[origin: WO9812708A2] A nuclear fuel sintered body, which when it burns up stresses the cladding tube of a fuel rod in an optimum minimum manner and contains a chemical compound of oxygen and at least uranium or plutonium, shows in a ceramographic ground section first (1) and second (2) micrographs associated each to a sintered granule. The first micrograph (1) has a first pore size distribution (I) and the second micrograph (2) has a second pore size distribution (II) in relation to the surface of the respective micrograph. The sum (III) of both pore size distributions has first (M1) and second (M2) maxima. A process for producing such a nuclear fuel sintered body and a fuel rod with a cladding tube and such a nuclear fuel sintered body are also disclosed.
