Abstract

1,012,257. Fuel elements; reactor control rods. EUROPEAN ATOMIC ENERGY COM. MUNITY (EURATOM). March 4, 1964 [March 8, 1963], No. 9095/64. Heading G6C. [Also in Division B3] Fillings in tubes or in containers of annular cross-section are compacted by a pilger deformation, the ends of said tubes or containers being closed. The filling is preferably a precompressed powder and the articles so produced may be nuclear fuel elements or control rods, the latter being filled with boron carbide powder. Annular section rods are internally supported by a mandrel. The basic pilger process comprises mounting the tube on a mandrel between two opposed rolls rotated by a limited amount in opposite directions, the rolls having eccentric peripheral grooves which are conically tapered and extend over approximately 180 degrees of the periphery. After each rolling operation, the rolls release the tube, which is rotated axially through about 60 degrees before the next rolling operation commences. When the complete circumference has been rolled, the workpiece is axially displaced to move that portion reduced to the required size from the working area, and the process is then repeated. The apparatus comprises a pair of pilger rolls 10, a drive 11 for rotating the fuel rod 14, mandrels 12a, 13a and chucks 12, 13. The fuel rod is traversed between the pilger rolls by a carriage 15 driven by a leadscrew 19. Fuel rod end plugs 14c are welded to the can. The mandrels 12a, 13a may be replaced by further fuel rods in a continuous process. Members such as wires, cables and struts may be placed in the container prior to rolling. Where the container is formed by the annular space between two concentric tubes, the inner tube is internally supported by a mandrel.
