| abstract | 880,662. Nuclear fuel elements; nuclear reactor control rods. GENERAL ELECTRIC CO. Sept 14, 1959 [Sept. 29, 1958; Oct. 20, 1958], No. 31229/59. Class 39(4) [Also in Group XXII] A nuclear reactor core element (i.e. a fuel or control rod) comprises an elongated plate provided with a plurality of elongated sealed channels of lenticular or irregular but substantially rectangular cross-section containing active nuclear material (i.e. fuel or neutron absorbent material) in the form of closely packed particles the major axis of the cross-section being parallel to the principal exterior surface of the plate. In one arrangement three holes are drilled in a stainless steel billet and filled with powdered uranium dioxide, 20% enriched, which is compacted; the open ends of the holes are sealed and the billet rolled to produce the fuel plate shown in Fig. 2. In another arrangement a stainless steel strip is rolled to form a pair of U-shaped channels with a corrugated strip between them as shown in Fig. 3; the ends of the strip may be welded at 26, 28 or the flanges may be compressed to bond them together. One end of the billet is closed by stamping or forging and the billet is then filled with uranium dioxide powder and its open end closed. The billet is then rolled to produce the flat fuel plate shown in Fig. 4. Flat or curved fuel plates may be secured at their edges to side plates to form a fuel element assembly, Figs. 5 and 6 (not shown). Control rods may be made in the same way using a neutron absorbent such as boron carbide instead of fuel in the billet. A long flat control plate as in Fig. 2 or Fig. 4 may be welded to two short ones to form a cruciform control element, Figs. 7 and 8 (not shown). |
