Abstract

873,794. Nuclear reactors. ALLMANNA SVENSKA ELEKTRISKA A.B. Dec. 23, 1959 [Dec. 30, 1958], No. 43646/59. Class 39(4). The cover of the pressure vessel of a reactor employing heavy water as moderator and as coolant comprises a flat vessel for containing, a radiation protection liquid and consists of an upper plate 1 and bottom plate 2 having extending therebetween a number of channels for the passage of fuel elements. The plates 1, 2 are of carbon steel and each passage comprises an outer tube 4 of carbon steel and an inner tube 5 of stainless steel, the lower side of the plate 2 which is in contact with the water being clad with a stainless steel layer 3. The tube 4 is welded at 6 to the plate 1 and has a flange 7 clad with a stainless steel layer 8. A slot 9 is in the tube 5 receives a split ring 10 embraced by a stainless steel ring 11 which abuts the layer 8 and is welded at the layer 3. The lower end of the tube 5 is welded at 16 to the ring 11. A torque from the tube 5 is transmitted to the plate I by external teeth 12 on the tube 5 engaging slots 14 in a ring 13 welded at 17 to the plate 1.
