Patent GB-852877-A (GB)
Title: Improvements in or relating to nuclear reactors and fuel elements therefor
IPC: G21C1/30
Filed: 1958-05-29
Abstract: 852,877. Nuclear reactors. GENERAL DYNAMICS CORPORATION. May 29, 1958 [June 10, 1957 ; May 9, 1958], No. 17232/58. Class 39(4). In a solid homogeneous reactor a mixture of fuel and moderator is placed in tubes or used in a single mass so that the neutron temperature varies simultaneously with the moderator temperature. The reactor has a large prompt negative temperature coefficient of reactivity given by the use of materials in the homogeneous mixture having large resonance cross-sections so that the resonance capture exceeds 3% and the neutron doppler effect is large, and of poisons such as cadmium, samarium, and boron-carbon-aluminium alloy so that the relative rate of capture in the poison increases with temperature. These mechanisms are in addition to more conventional ones such as the increase of neutron leakage and reduction of fission cross-section with increasing temperature. As the reactor is inherently safe it is suitable for teaching and general research. It is low powered and consists of a reactor tank 20, which may be of aluminium, containing fluid coolant 45 and a core assembly 11. The core contains vertical fuel elements 24 supported by grids 28 and 30 of aluminium. It is surrounded by a reflector 12 of carbon, beryllium, beryllium oxide or other moderator which is extended on one side as the thermal column 15. The whole reactor is enclosed by concrete shielding 13 in which access ports 16 and 17 are provided. The tank has a removable lead cover 22 and the thermal column a cover of lead 70 and concrete 68. The access ports also have covers. The tank top is strengthened by a steel ring 23. The fuel elements consist of aluminium cylinders 25 containing a solid body 26 formed of a homogeneous mixture of fissile material and solid moderator, for example beryllium, beryllium oxide, zirconium hydride or carbon, and a strong resonance absorber, for example uranium 238 or thorium 232, under a solid reflector 27. The dummy elements 29 contain moderator only. The heads 41 of the elements have lips 42 by which the elements are lifted. The control rods 14 have stainless steel lower tubes 54 which contain absorber (boron carbide) and slide in aluminium tubes 61 and engage the upper rod 53 through electro-magnets. Coolant (light or heavy water) enters through a pipe 38 and flows upwards through the core into the reactor tank which it leaves at 51. Poison elements may be added to the fuel elements for example at 74 or to the reflector.

Title: Improvements in or relating to an arrangement for the generation of radiation of charged particles of great energy
IPC: G21K1/10
Filed: 1951-07-24
Abstract: In order to increase the scattering of high power radiation from a generator, such as a betatron, without the production of more than a negligible proportion of X-rays, a scattering element, of a material of atomic number of at least 40, is placed in the path of the radiation outside the generator.  Its thickness is such that the intensity of X-rays produced is small in relation to the radiation transmitted and, in the case of gold or lead, it may be between 5 and 200 microns.  For convenience in bringing a desired one of a number of scattering elements into the operative position, several may be mechanically linked together and set up in front of the generator.

Heading B1B. Alcohol is distilled off in pot still 12 from fermented liquor produced from grain, the residual liquor (pot ale) is concentrated in multiple-effect evaporator 21, 29, and some of the vapour from liquid/vapour separator 30 is employed to heat the alcoholic liquor as it is pumped through plate-type heat-exchanger 16 which is connected to the still 12. Valve 61 is set so that the liquor does not boil in heat-exchanger 16, 'but only on passing through the valve. Separator 60 discharges vapour and hot liquors separately into pot still 12. Some of the pot ale vapour from separator 30 is also used to heat the alcohol being distilled in pot still 14. Multiple-effect evaporator 21, 29 is connected to multipleeffect evaporator 22, 39 via pot ale storage tank 36 and vapour-line 47. The heatexchangers associated with the quadrupleeffect evaporator are of the plate-type.
