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 afuel rod for a nuclear reactor, the cladding of the rod containing a plurality of pellets ofnuclear fuel stacked in the axial direction of the cladding and two closure plugs, one ofthe plugs or the upper plug being traversed axially by the channel for filling the claddingof the rod with an inert gas and the sealed closure by welding of the filling channel of theupper 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 thefilling channel, this method allowing for inspection of the conditions for implementingand carrying out the sealed closure of the upper plug by welding, efficiently and withoutextending the time needed for the manufacture of the fuel rod.
