摘要： A welding apparatus for welding an end plug on the end of a pellet filled nuclear fuel rod includes a holding mechanism, an abutting member, a torch and a pressing mechanism. The holding mechanism is for holding the external periphery of the fuel rod with the end plug attached thereto. The abutting member is disposed opposite to the holding mechanism, and the end plug of the fuel rod butts up against the abutting member. The torch is disposed between the holding mechanism and the abutting member, and is placed diametrically opposite to the external surface of the fuel rod. The holding mechanism and the abutting member are made so that the distance therebetween can be adjusted, and the pressing mechanism is provided on one of the holding mechanism or the abutting member, and operates to move the holding mechanism and the abutting member to approach each other. In a welding apparatus of such a design, the fuel rod is held by the holding mechanism, and the pressing mechanism pushes the holding mechanism toward the abutting member, and while retaining such a position at a constant compressive force, welding of the end plug is performed. Therefore, the welding is performed without being affected by the variations in the compressive force caused by welding heat distortions, thereby providing a weld of high integrity and quality.

摘要： The apparatus enables measurement of the amount of contaminant in a welded portion to high accuracy and in a short time, using an X-ray fluorescence inspection apparatus. The end portion of a fuel rod having a bead portion on an end surface of an end plug is covered with an approximately cylindrical cap, with the bead portion exposed via a central aperture. The material of the cap is preferably titanium. With titanium the fluorescent X-ray radiation has a different wavelength from that of tungsten and zircaloy, and the amount of fluorescent X-ray radiation detected by a detector at a diffraction angle of the spectrum W-L &agr; of fluorescent X-ray radiation for tungsten is less than those for tungsten and zircaloy. Therefore, while the fluorescent X-ray radiation of the cap which covers the end surface of the end plug around the bead portion results in noise, the amount of this fluorescent X-ray radiation measured by the detector is much smaller than for the tungsten and the zircaloy of the bead portion.
