Abstract

749,064. Nuclear reactors. TEXACO DEVELOPMENT CORPORATION. April 8, 1953, No. 9521/53. Class 39 (4). [Also in Group XXVI] In a nuclear reactor the fissionable material is maintained in a fluidized phase or is used to fluidize a moderator. The reactor 11 contains particles of compounds comprising U<SP>235</SP>, U<SP>238</SP> and/or Pu, fluidized by a gas pumped at 34 through 37 and extracted at 18 through a cyclone separator, fines being returned at 21 from this separator and at 29 from an ultrasonic or electrostatic, separator 28. The fluidizing medium may be air, hydrogen, deuterium or helium. A coolant is preheated at 23, and then heated in a coil 38 to drive a turbine 42. Alternatively or in addition to this system, a coolant in tubes 38a in the reactor walls passes through a heat exchanger 40. Na, K, Bi, Pb and Sn in their molten phases, water and/or heavy water, diphenyl, He, and H are described as suitable coolants. Particles of graphite or beryllium may be included in the reactor if the fluidizing medium is not of itself sufficient as a moderator, and particles of Zr, Mg, or A1 may be included to improve the heat transfer. In response to temperature rises at 47, 48, 49 or increase in radiation at 51, 51, rods 14, 16 of Cd or B are advanced into the reactor; or the rate of flow or the pressure of the fluidizing medium is increased, or the proportion of hydrogen to deuterium in this medium is increased, thus controlling the nuclear reaction. A part of the fluidizer stream is processed at 32 to extract radio-active isotopes. The vertical rods 16 retard the reaction rapidly if the flow of fluidizer ceases and the fissionable particles fall. Uranium hexafluoride gas may be used to fluidize moderator particles of graphite or beryllium oxide. The coolant may also be used as the fluidizer, Fig. 2 (not shown). The reacting particles may be fluidized mechanically, Fig. 4, by helically pitched blades 164, with the aid of a fluidizing medium admitted at 185 and removed through filters 188, the reactor and blades 164 being cooled by a coolant admitted at 153, 156, 159, 169. In heat exchangers 176, 194, heat is extracted from the coolant and from the fluidizer.
