Title: Heat transport system

Abstract

A falling bed of ceramic particles receives neutron irradiation from a neutron-producing plasma and thereby transports energy as heat from the plasma to a heat exchange location where the ceramic particles are cooled by a gas flow. The cooled ceramic particles are elevated to a location from which they may again pass by gravity through the region where they are exposed to neutron radiation. Ceramic particles of alumina, magnesia, silica and combinations of these materials are contemplated as high-temperature materials that will accept energy from neutron irradiation. Separate containers of material incorporating lithium are exposed to the neutron flux for the breeding of tritium that may subsequently be used in neutron-producing reactions. The falling bed of ceramic particles includes velocity partitioning between compartments near to the neutron-producing plasma and compartments away from the plasma to moderate the maximum temperature in the bed.

  • There is provided a solar collector comprising a straight tubular metal heat pipe having an evaporator section and a condenser section. Two elongate metal absorber plates are longitudinally connected to the evaporator section and are bent in an outwardly extending X-shape with respect thereto. The absorber plates are in thermally conductive contact with the evaporator section.
  • A support column for a heavy component of a liquid metal fast breeder reactor heat transport system which will deflect when the pipes leading coolant to and from the heavy component expand or contract due to temperature changes includes a vertically disposed pipe, the pipe being connected to the heavy component by two longitudinally spaced cycloidal dovetail joints wherein the distal end of each of the dovetails constitutes a part of the surface of a large diameter cylinder and the centerlines of these large diameter cylinders intersect at right angles and the pipe being supported through two longitudinally spaced cycloidalmore » dovetail joints wherein the distal end of each of the dovetails constitutes a part of the surface of a large diameter cylinder and the centerlines of these large diameter cylinders intersect at right angles, each of the cylindrical surfaces bearing on a flat and horizontal surface.« less

  • This patent describes a combination with a sodium cooled reactor having an intermediate heat exchanger for extracting heat in a nonradioactive secondary sodium loop from the sodium rector. It comprises: first and second upstanding closed cylindrical vessels, one of the cylindrical vessels being exterior of the other of the cylindrical vessels; the other of the cylindrical vessels being interior, smaller, and concentric of the larger cylindrical vessel so as to define between the inside of the larger vessel and the outside of the smaller vessel an interstitial annular volume; at least one feedwater inlet plenums at the bottom of themore » larger vessel communicated to the interstitial annular volume; at least one feedwater outlet plenums at the top of the larger and outer vessel communicated to the interstitial annular volume; tubes communicated to the feedwater inlet plenum at the bottom of the vessels and to the steam outlet plenum at the top of the vessel; a first conduit; a large submersible electromagnetic pump; and a jet pump having an inlet, a venturi, and a diffusing outlet.« less
