Abstract
The nuclear fuel element according to the invention comprises a can, which is sealed at its ends by plugs, whereof a cylindrical portion is force fitted into the can. The internal diameter of the can can vary between a maximum diameter and a minimum diameter, the diameter of the cylindrical portion being equal to said minimum diameter. Three serrations machined on the cylindrical portion form beads, whose thickness is equal to half the difference between the maximum diameter and the minimum diameter of the can.
Claims2
A nuclear fuel element comprising a tubular can having an internal diameter between a maximum diameter and a minimum diameter, which is sealed at at least one end by a plug having a cylindrical portion force fitted into said can, wherein the cylindrical portion has a diameter equal to the minimum diameter of the can and has at least three serrations oriented in accordance with the generatrixes of said cylindrical portion and which are regularly spaced, said serrations forming overhanging beads with respect to said cylindrical portion over a thickness equal to half the difference between the maximum diameter and the minimum diameter of the can.
