Abstract
Nuclear reactor with a MHD driven gas-core vortex, that may be preceded by an enrichment section and followed by a reprocessing section, both sections based on gas-cores that are MHD driven gas-vortexes, in which the nuclear reactor functions with a mixture of e.g. UF.sub.6 and one or more light gases such as H.sub.2, DT, He.
Claims3
Apparatus for the stable confinement of a fast rotating gaseous mixture of a heavy gas component and a light gas component comprising:
- an elongated reactor vessel constructed for nuclear fission reactions having a wall of circular cross section and end covers;
- means for cooling the reactor vessel;
- at least one supply pipe for supplying a gaseous mixture of heavy and light components to the interior of the vessel;
- means for imparting rapid rotation to the gas in the center of the vessel so that the heavy gas component, by means of a high pressure gradient caused by centrifugal forces, moves to the inside of the vessel wall and so that the light gas component forms a central gas column extending axially in the vessel, said means for imparting rapid rotation including means for ionizing the gas column, means for inducing an axial magnetic field extending the length of the vessel so that the gas in the vessel is subjected to the field, and means including at least one electrode mounted on at least one end cover of the reactor vessel in the center of the cover, from which an ionized column of light gas extends along the central rotation axis of the gas mass, for producing a radial electrical potential between the ionizing means and the vessel wall;
- means for flowing the heavy gas component in the form of a gas envelope axially along the vessel wall and then axially in an opposite direction;
- and supply and discharge pipes communicating with the ionized gas column, and a neutron reflector-moderator jacket mounted between the wall of the reactor vessel and the magnetic field-inducing means, said vessel wall being lined with electrode rings which are electrically insulated from each other, openings being provided in the inner surface of the wall of said reactor vessel which give access to annular cavities surrounded by cooling channels, said inner surface and the walls of the cavities being made of carbon or of a carbon compound.
Method for effecting a rotation in a mass of light and heavy gas components contained in a rotationally symmetric housing comprising effecting a gas discharge arc functioning as a central electrode along an axially symmetric pattern along the lines of force of an axial magnetic field, applying a radially symmetric electric potential between this central arc and the enveloping wall of the housing, under whose influence ions move in a radial direction from the arc to the wall producing thereby a radial electric current in the gas normal to the axial magnetic field, whereby a force is exerted on the partially ionized gas, which force as a result of the rapid rotation produced in this way compensates the frictional forces between the gas and the wall and thus produces a controllable stationary rotation, whereby light gas components and heavy gas components are compressed at the wall according to a pressure exponentially increasing with the radius, the pressure increase being attended by a separation of light and heavy gas components, in such a manner that the mass of gas passes successively through different zones of the housing lying one behind the other, wherein the wall of the vessel includes electrodes which form hollow chambers through which an electrically conductive coolant is propelled under the influence of the magnetic field present and of the local artificial radial electric fields.
