Abstract

Process and device for the protection of combustible assemblies of nuclear reactors, constituted by a plurality of elongated shaped fuel elements and covered by a protective sheath, associated with each other by a rigid structure, the procedure characterized in that the perforation of said sheath is caused when it has an inflammation greater than a given threshold.
