Abstract

910,515. Nuclear reactors. ROLLS-ROYCE Ltd. May 19, 1960 [May 1, 1959], No. 15054/59 Class 39 (4). [Also in Group XXIX] A nuclear reactor 50 has double - walled fuel - element receiving tubes 51 through which steam is fed for cooling purposes and the thin inner walls of which are supported by pressurized helium which is fed to the space between the walls from storage bottles 55 via a control valve 54 (see Group XXIX), which ensures that the helium pressure is equal to or slightly less than the pressure of the cooling steam. A pump 74 continuously circulates the heavy water moderator liquid via coolers 71, 73. The control tubes 80 are fed with heavy water from a dump tank 81 and the level of the heavy water in the tubes is varied, to vary the reactivity of the reactor. A pump 98 draws helium from the bottles 55 to provide a helium atmosphere for the dump tank 81 from which it passes to a weir tank 101, a cooler 103, a flame trap 105 and a recombiner 106. The weir tank 101 is located above and is connected to the reactor tank 50 and provides a collection space for the dissociation products-deuterium and oxygen-whiich are carried to the recombiner 106 which receives make-up oxygen from a bottle 120.
