摘要： A liquid metal-cooled nuclear reactor includes, within a reactor pressure vessel, a primary electromagnetic pump (EMP) circulating liquid metal coolant through the reactor core and a backflow EMP. The nuclear reactor may be configured to at least partially mitigate liquid metal coolant backflow in response to a primary EMP failure. The backflow EMP is coupled in series with the primary EMP within the reactor pressure vessel. The backflow EMP may be selectively activated in response to failure of the primary EMP to mitigate liquid metal backflow through the primary EMP. The primary EMP and backflow EMP may receive power from separate power sources. Multiple backflow EMPs may be coupled in parallel to the primary EMP via parallel liquid metal coolant lines. A nuclear reactor may include multiple primary EMPs and multiple sets of backflow EMPs, where each separate set of backflow EMPs is coupled to a separate primary EMP.

摘要： A fast breeder reactor having an intermediate heat exchanger (21) into which a liquid metal in one of both cooling systems of a primary cooling system and a secondary cooling system of the fat breeder reactor is introduced as a primary fluid and a liquid metal in the other cooling system as a secondary fluid, the secondary cooling system being furnished with a pump which causes the liquid metal in this secondary cooling system to flow; characterized in that the intermediate heat exchanger (21) is constructed of a magnetic field generator (23, 24), and a channel which is so formed that its flow direction is set to a direction traversing a magnetic flux produced by the magnetic field generator, the channel being partitioned by an electrically-conductive heat transfer plate (30) to define a primary cooling system channel (31) through which the primary fluid is passed and a secondary cooling system channel (32) through which the secondary fluid is passed. When one of the primary and secondary fluids is caused to flow by the pump (6) within a magnetic flux established by the magnetic field generator (23, 24) and while defining an angle to the magnetic flux, current is induced, and the other fluid flows subject to the current and the magnetic flux of the magnetic field generator, whereby heat is exchanged between both the fluids through the heat transfer plate (30) during the flow of both the fluids. The common structure achieves a heat exchange function and a pumping function which can contribute to the miniaturization of the fast breeder reactor.

摘要： Die vorliegende Erfindung betrifft eine Vorrichtung zur Erzeugung eines variablen Drehimpulses oder Drehmomentes, die ein Behältnis (1), das teilweise mit einem magnetisierbaren Fluid (2) gefüllt ist, und eine Einrichtung zur Erzeugung eines oder mehrerer rotierender oder wandernder Magnetfelder aufweist, mit denen das magnetisierbare Fluid (2) in dem Behältnis (1) auf einer geschlossenen Bahn kontinuierlich bewegt werden kann. Die Einrichtung zur Erzeugung der rotierenden oder wandernden Magnetfelder weist mehrere elektrische Spulen (4) auf, deren Spulenachsen in der Bahnebene angeordnet sind. Durch diesen Aufbau lässt sich ein variabler Drehimpuls ohne mechanisch bewegte Teile oder die Notwendigkeit externer Magnetfelder erzeugen. Die Vorrichtung ermöglicht bspw. eine einfache und kostengünstige Lageregelung von Raumfahrzeugen.
