摘要： For welding a grid formed by sets of plates disposed orthogonally and whose endmost parts are secured to a surround, it is placed in a shaping and mechanically holding frame allowing access to the point to be welded. The frame containing the grid is then placed on a revolving device belonging to a roundabout, at a first welding position and welding is carried out therein on at least one face of the grid by means of a welding member movable in two perpendicular directions for bringing it at right angles to each of the welding points on the face. The frame is then brought to a second welding position in which the plates are welded to the surround by means of a second welding member movable in only one direction, after rotation through 90.degree. of the frame by means of the revolving device; and the operations are repeated as necessary until the whole of the welds have been executed.

摘要： The present invention relates to a spacer grating for fuel element in a nuclear reactor of the PWR type, said grating being constituted by intersecting plates. Over the greater part of the walls equipped with springs, double springs comprise two active parts on either side of the wall on which the double spring is placed, allowing the symmetrical action of this spring on two different pencils inside two adjacent cells. On the other walls equipped with springs, single springs comprise one active part only, disposed in one of the two cells separated by the wall on which is placed the spring of which the other part is not capable of coming into contact with a fuel pencil. The invention is particularly applicable to the manufacture of fuel assemblies in nuclear reactors of the PWR type.
