Abstract

806,985. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 15, 1957 [July 17, 1956], No. 22021/56. Class 39(4). A cooling system for a heterogeneous reactor in which a coolant gas is supplied to the central region of the moderator structure whence it flows outwardly to a heat exchanger, comprises a graphite core 1 having vertical channels 2 each receiving a stack of fuel elements 3, each element being surrounded by a tube 4 carried thereby (Fig. 1a (not shown). The tubes 4 define an annular gas entry passage 2a between their outer surfaces and the surface of the channel 2 and an annular gas exit passage 2b between their inner surfaces and the elements 3, the gas being supplied at 36 to both ends of the channel 2 and reaching the passage 2b through apertures 4a in the central tube 4, the heated gas 37 leaving through tubes 5, 7. Gaps 4b between the tubes 4 permit gas leakage between the passages 2a, 2b. The coolant gas also enters control rod channels 9 connected by holes 10 to the channels 2. The channels 2 are arranged in square-shaped groups of sixteen channels, the tubes 5 of each group being connected to an upper header vessel 6 connected at 14. for limited vertical movement, to a charging tube 13 in the pressure vessel wall 15. Adjacent header vessels 6 are connected together through ports 18 having flexible joints 19 permitting limited lateral movement. The control rod tube 16 of the group is located by a pressure seal 17, and the tubes 7 of each group are connected to a lower header vessel, Fig. 4, (not shown) somewhat similar to vessel 6. A circulator 29 feeds gas 30a into the pressure vessel 15 through a duct 30, the heated gas 31a from the vessels 6 being conducted to a heat exchanger 32 through a duct 31 within the duct 30. A pressure shell 33 surrounds the exchanger 32. A further circulator (not shown) feeds gas to a duct 34, the duct 35 receiving heater gas from the lower header vessels whence it flows to a further heat exahnger. In a modified arrangement, Fig. 6, (not shown) the fuel elements are longitudinally finned each element having a sleeve (which may be double-walled) functioning in lieu of a tube 4. The cooling system may also be applied to a heavy-water moderated reactor.
