Abstract

Cylindrical fuel rod for a nuclear reactor, with a locally flexible metal sheath surrounding a number of closely in contact cylindrical fuel tables, which in novel fashion are provided with an axial expansion relief capability at the appropriate end surfaces to take up individual axial expansion during operation and avoid differential axial expansion between them and the sheath, while an intermediate layer of low shear strength, partic. graphite, siloxane or silicon is provided between the outer surface of the fuel tablets and the sheath to favour a peripheral distribution of stresses in the sheath and reduce the likelihood of longitudinal crack formation therein, which could result from local concentrations of peripheral expansion forces. Eliminates cracking of the sheath due to local deformation.
