Abstract

1,130,329. Reactors. BABCOCK & WILCOX Ltd. 4 Feb., 1966 [24 Feb., 1965], No. 5118/66. Heading G6C. An integral gas-cooled nuclear reactor has a core 3 and a vapour generating heat-exchanger 5 arranged within a pressure vessel 2, and a coolant gas space including means defining a path through which the coolant gas flows successively through the core 3 and the heatexchanger 5, the wall of the pressure vessel 2 being included in the boundary of the gas space and lined internally by cooling tubes 18 connected to the heat-exchanger 5 so that water flows in sequence through the cooling tubes 18 and the heat-exchanger 5. The heat-exchanger 5 and the core 3 are separated by a cylindrical biological shield 4. The vessel 2 is fabricated from metal plate and has cooling water tubes 7 welded to its outer surface. These tubes 7 are cooled by the passage through them of condensate from a turbine driven by steam generated in the heat-exchanger 5. The vessel 2 is insulated on its inner surface by a layer 8 of corrugated stainless steel plates and is encased in a concrete shell 9. The heat-exchanger 5 consists of tubes lying in planes extending radially from the vessel centre and each is formed of horizontal tube lengths connected together by return bends. Inlet and outlet feed branches 11, 12 are provided for the heatexchanger 5, the former being connected to the heat-exchanger 5 by the tubes 18 which form an internal tube lining of the vessel 2. A thermal shielding 19 located at the upper end of the vessel 2 comprises a covering 20 of heat-resisting steel lined on the underside with hollow metal castings 21 filled with refractory insulating material. Circulating fans 13 are mounted at the ends of ducts 27 connected to a plenum chamber 6 beneath the core 3, gas being withdrawn from the heat-exchanger 5 along the passages containing the fans 13 and then passed along the ducts 27 to the plenum chamber 6. From the plenum chamber 6 the gas passes upwardly through the core 3, then over the edge of the shield 4 and downwardly over the heatexchanger 5. Water fed into the inlet branches 11 passes along the tubes 18 and cools the vessel 2, before being converted into steam in the heat-exchanger 5 and passed through the outlet branches 12 to the steam turbine.
