Fuel rod for a nuclear reactor having an improved end plug assembly
This patent describes, in a nuclear reactor fuel rod including a fuel tube and nuclear fuel and gas under pressure disposed within the tube, an improved end plug assembly which seals opposite ends of the tube so as to confine the fuel and pressurized gas within the tube. The assembly comprises: (a) a pair of end plugs attached in sealing relationship to the opposite ends of the tube; (b) at least one of the end plugs having an inner body portion fitted within the end of the tube and an outer body portion extending outwardly from the tube; and (c) the one end plug having a cavity defined therein which communicates with the fuel tube, the cavity including an outer region within the outer body portion and an inner region within the inner body portion, the outer cavity region being undercut relative to the inner cavity region.
