Abstract

Improvements in fuel elements for nuclear reactors, characterized by comprising a column of ceramic fuel pellets enclosed in a perfectly fitting metal casing, with a generally uniform and smooth conduit; The fuel pellet column is divided by at least one pellet of a non-fissile material, inert for the fuel and for the casing, and which has the property of retaining its resistance under irradiation and, at least part of This chip has a reduced cross section inside which the casing is interlocked.
