摘要： Before welding, the plug and the sleeve of the fuel rod being in the welding position at the welding station, the sleeve and the plug of the fuel rod are rotated about their common axis with the aid of rotation means, images are taken along the periphery of the fuel element to obtain digitized images, the digitized images are analyzed to determine the position of the joint plane between the sleeve and the plug of the fuel rod, and the rotation of the fuel element is verified. It is deduced whether it is possible to perform the welding or not. If welding is performed, images are taken of the fuel element along the periphery of the fuel element, in the vicinity of a joint line between the sleeve and the plug, to obtain digitized images which are analyzed to check the conformance of a weld made along the joint line.

摘要： A method of inspecting an operation of sealed closure by welding an end opening of a filling channel axially traversing an upper plug for closing the cladding of a fuel rod for a nuclear reactor, the cladding of the rod containing a plurality of pellets of nuclear fuel stacked in the axial direction of the cladding and two closure plugs, one of the plugs or the upper plug being traversed axially by the channel for filling the cladding of the rod with an inert gas and the sealed closure by welding of the filling channel of the upper plug being carried out after filling the cladding with inert gas, in a filling apparatus, by melting central part of the end of the upper plug adjacent to the opening of the filling channel, this method allowing for inspection of the conditions for implementing and carrying out the sealed closure of the upper plug by welding, efficiently and without extending the time needed for the manufacture of the fuel rod.
摘要翻译：通过焊接填充通道的端部开口来轴向地穿过上部塞子以封闭用于核反应堆的燃料棒的包层来检查密封封闭件的操作的方法，包含多个核燃料颗粒的棒的包层堆叠在包层的轴向和两个封闭塞子中，插塞或上塞子中的一个被通道用轴向横穿，用于用惰性气体填充杆的包层，并且密封的封闭件通过焊接上部的填充通道在填充装置中通过熔化上部塞子的端部的中心部分与填充通道的开口相邻的方式在惰性气体填充包层之后进行插塞，该方法允许检查实施和执行的条件通过焊接，有效地且不延长制造燃料棒所需的时间来密封上部塞子的封闭。
