摘要： A molten salt fission reactor. The reactor comprises a reactor core, which comprises a plurality of fuel tubes. Each fuel tube contains a fuel salt and a gas interface. The fuel salt is a molten salt of one or more fissile isotopes. The gas interface is a surface of the fuel salt in contact with a gas space during operation of the reactor. The reactor also comprises a fuel salt cooling system, which is configured to cool the fuel salt. The cooling system comprises a heat exchanger and a coolant tank. The coolant tank contains a coolant liquid in which the fuel tubes are at least partially immersed. The heat exchanger is for extracting heat from the coolant liquid. The fuel salt cooling system is configured such that during operation of the reactor, for all points within the fuel salt within each fuel tube except at the respective gas interface: (I)

摘要： Configurations of molten fuel salt reactors are described that allow for active cooling of the containment vessel of the reactor by the primary coolant. Furthermore, naturally circulating reactor configurations are described in which the reactor cores are substantially frustum-shaped so that the thermal center of the reactor core is below the outlet of the primary heat exchangers. Heat exchanger configurations are described in which welded components are distanced from the reactor core to reduce the damage caused by neutron flux from the reactor. Radial loop reactor configurations are also described.

摘要： A nuclear fission reactor comprising a core, a pool of coolant liquid, and a heat exchanger. The core comprises an array of hollow tubes which contain molten salts of fissile isotopes. The tube array is at least partly immersed in the pool of coolant liquid. The tube array comprises a critical region, where the density of the fissile isotopes during operation of the reactor is sufficient to cause a self-sustaining fission reaction. Heat transfer from the molten salts of fissile isotopes to the tubes is achieved by any one or more of natural convection of the molten salts, mechanical stirring of the molten salts, and oscillating fuel salt flow within the tubes. The molten salts of fissile isotopes are contained entirely within the tubes during operation of the reactor.

摘要： Die vorliegende Erfindung stellt einen Kernreaktor mit einem Kreislauf für flüssigen Kernbrennstoff dar, der im Gegensatz zu ähnlichen Systemen wie dem Flüssigsalzreaktor der Generation IV den Brennstoffkreislauf nicht gleichzeitig zur Abfuhr der Wärme verwendet. Die Kühlung geschieht vielmehr durch einen getrennten, in engem Wärmekontakt mit der Leitung des Flüssigbrennstoffs stehenden Kühlkreislauf. Auf diese Weise lassen sich die Vorteile eines Flüssigbrennstoffs voll ausschöpfen, während gleichzeitig der Kühlkreislauf optimiert werden kann. Dadurch ergeben sich erhebliche Vereinfachungen der Sicherheitsvorrichtungen. Dieser Reaktor hat überdies eine optimierte Neutronenökonomie und ist damit in der Lage, seine eigenen langlebigen Spaltprodukte zu deaktivieren, so dass nur kurzlebige radiotoxische Abfälle gelagert werden müssen. Mit dem Neutronenüberschuss können darüber hinaus langlebige radiotoxische Bestandteile aus abgebrannten Brennelementen heutiger Leichtwasserreaktoren deaktiviert oder medizinische Radioisotope produziert werden.

摘要： A molten salt breeder reactor that has a fuel conduit surrounded by a fertile blanket. The fuel salt conduit has an elongated core section. The geometry of the fuel conduit is such that sub-critical conditions exist near the input and output of the fuel salt conduit and the fertile blanket surrounds the input and the output of the fuel salt conduit, thereby minimizing losses.

摘要： The present invention relates to a method of adjusting the oxoacidity of a molten metal hydroxide salt, the method comprising the steps of: estimating a target concentration of at least one of H2O, O2-, and OH- in a molten salt of a metal hydroxide; providing an oxoacidity control component; and contacting the oxoacidity control component with the molten salt of a metal hydroxide to adjust the oxoacidity of the molten salt of a metal hydroxide. The method allows better utilisation of the available temperature range for a molten salt of a metal hydroxide by reducing the corrosive nature of the metal hydroxide.

摘要： A molten salt reactor is disclosed. In some embodiments, the molten salt reactor comprises a containment vessel; a molten salt chamber disposed within the containment vessel; a molten salt mixture disposed within the molten salt chamber; and a heat exchange system at least partially disposed within the molten salt chamber. In some embodiments, the molten salt reactor comprises one or more of a shutdown mechanism, a thermally activated failsafe mechanism, and/or a passive reactivity control system. The shutdown mechanism, for example, may be coupled with the molten salt chamber, the shutdown mechanism comprising a material that when inserted into the molten salt chamber will inhibit fission reactions within the molten salt mixture. The thermally activated failsafe mechanism, for example, may be coupled with the molten salt chamber, the thermally activated failsafe mechanism passively inhibits fission reactions within the molten salt mixture.
