The proposal concerns shaped, especially spherical, fuel elements which consist of fissionable or breeder material and a filler and are covered with a non-metailic cladding. An artificially increased porosity is given to the moided core and the cladding. For the coating, materials were selected which after sintering, exhibited an increased abrasion resistance. The considerntion of the abrasion of the molded bodies on each other or the surface abrasion by the reactor coolant is limited to the substance forming the cladding. This means that the coolant dissolves no fissionable material. The radioactive fission products produced in the interior of the fuel element do not appear in the coolant but are absorbed by the cladding material in the boundary layers. These fuel elements are especially appiicable in reactors with high operating temperatures. it is also proposed that the cladding eonsist of sintered high- melting metal oxides of elements with high atomic weight, such as barium oxide.
