A nuclear fuel element for use in power-producing nuclear reactors, comprising a circular metal cladding tube containing sintered cylindrical oxide fuel pellets, the tube being formed internally with a substantially cylindrical inner surface having a plurality of longitudinal ribs forming axially extending channels. The fuel pellets have chamfered endfaces creating toroidal spaces at the adjoining ends of the fuel pellets, the ratio of axial channel to toroidal space volumes including any pellet dishing being at most about one (1);
a process for the manufacture of such fuel element.
