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.

Abstract: Apparatus wherein a partially ionized mass of gas is enclosed by a rotationally symmetric, axially elongate housing and set in rotation by a force which arises as a result of a substantially axial magnetic field constant in time and an electric current having a non-zero vector component in the radial direction, whereby positively charged ions originating from a centralized axial gas discharge arc region and moving at a high speed of rotation set the whole mass of gas in rotation by pulse transfer, said housing being lined on the inside with annular wall electrodes segmented in non-azimuthal direction and arranged against each other; the inside wall of said housing at an extremity thereof curving toward the center axis and approaching a centrally mounted electrode of opposite polarity, the wall electrodes being connected with variable resistors which are adjusted so that the voltage applied to the wall electrodes increases blockwise from a minimum value at a chosen point on the axis of the housing to the grid-

Abstract: Apparatus comprising a vessel provided with electrodes, magnet and cooling means designed for the stable confinement of an ionized gaseous mixture or a plasma inside a heavy gas envelope that moves at high speed along the inside of an electrically gas-repelling vessel wall. The apparatus may be used not only for bringing about thermonuclear reactions, but also for separating gases of different specific mass from one another.
