摘要
Method of automatically filling jacket tubes for fuel rods of nuclear reactors with nuclear fuel pellets in combination with subsequent closure of the jacket tubes by automated welding of end caps thereon, which includes introducing the nuclear fuel pellets row-wise into a receiving tube of a collecting magazine therefor, passing the magazine containing the nuclear fuel pellets through a drying furnace to remove traces of moisture therefrom, subsequently delivering the magazine containing the moistureless nuclear fuel pellets to a filling station to which, respectively, an empty jacket tube has been fed from a tube magazine, weighing the empty jacket tube, then filling the empty jacket tube with fuel pellets in a column from the receiving tubes of the collecting magazine by mechanically displaced pushrods until a given extent of fullness thereof depending upon the length and weight of the pellet column has been attained, delivering the filled jacket tube to a further processing station for introducing insulating tablets, support sleeves and springs thereto and, after final checking, transferring the jacket sleeve to welding apparatus for welding end caps thereon.
