Abstract

883,717. Reactors. BABCOCK & WILCOX Ltd. March 31, 1960 [April 3, 1959], No. 11438/59. Class 39(4) In a heterogeneous nuclear reactor, water flows upwards through the core and acts as both coolant and moderator. The core is formed of vertical fuel and control rods supported at their ends, within the cylindrical pressure vessel, by an upper and a lower lattice having a cellular structure. The sides of each cell incorporate a vertical tube through which flows the coolant from a fuel chamber. As shown, water flows into pressure vessel 1 through inlet 14 and part moves upwards through passages 18, 28 52 and by apertures 19, 26 into compartments 51 of the upper core support 37. From 51, water flows through apertures 47 in plate 45 through the fuel element chambers 31 into the lower chamber 67. Further coolant from 14 flows downwardly through passage 72 and enters 67 through orifices 73. From 67, part of the coolant flows upwards through orifices 74 over the outside of the control rods 32, into chamber 95 and the remainder passes upwardly through the inner fuel element chambers 31 through tubes 80 to 95. The coolant discharges from 95 to the outlets 13. Each control rod 32 has a lower follow up section 34 of low neutron capture cross section material and each fuel element chamber container 56 is substantially surrounded by the control rod ribs 33. Each control rod rests on a resilient stop 75. Specification 883,716 is referred to.
