Abstract

1,081,674. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 22, 1964 [Jan. 8, 1964], No. 959/64. Heading G6C. A water-cooled reactor has its core penetrated by two groups of pressure tubes containing fuel, steam being generated in the first group and superheated in the second group; each pressure tube of the second group has a wall tube 5 associated with it to define with the pressure tube a closed chamber 6 of chamber cross-section, through which a fraction of the feed water is circulated to cool the pressure tube; the heated water is used to preheat the main feed water supply. The core comprises a D 2 O containing tank 9 through which the pressure tubes 3a (steam generating) and 3b (superheating) pass. A second tube 16 is preferably placed between the fuel 2b and the wall tube 5, and the space 17 between these two tubes is closed at the top to provide an annular layer of stagnant steam. The pressure tubes are zirconium and the tubes 16 stainless steel; tubes 16 may be placed in direct contact with the wall tubes 5 and the space 17 dispensed with; the tubes 16 are retained to protect the zirconium from damage caused by the fuel elements. Coolant circulation.-Light water is fed by a pump 11 to the lower ends of the steam tubes 3a in which boiling takes place. Steam and water pass to a steam drum 12 from which steam passes, via a drier 13, to the superheating tubes 3b; hot water from the steam drum 12 passes back to the water inlet. A small fraction of feed water passes through a valve 14 to the annular chamber 6 and thence to the steam drum 12.
