Abstract
(DE)
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.
(EN)
The present invention relates to a nuclear reactor with a circuit for liquid nuclear fuel which, in contrast to similar systems such as the generation IV liquid salt reactor, does not use the fuel circuit at the same time to remove heat. The cooling is provided instead by a separate cooling circuit in close thermal contact with the conduit of the liquid fuel. In this way, the advantages of a liquid fuel can be fully exploited, while at the same time the cooling circuit can be optimized. This results in considerable simplifications of the safety devices. This reactor also has an optimized neutron economy and is thus able to deactivate its own long-life fission products, such that only short-life radiotoxic waste has to be stored. With the neutron surplus, moreover, long-life radiotoxic constituents from spent fuel in today's light-water reactors can be deactivated or medical radio-isotopes produced.

L'invention concerne un réacteur nucléaire comportant un circuit de combustible nucléaire liquide. Contrairement à des systèmes similaires tels que le réacteur à sels fondus de génération IV, le réacteur selon l'invention n'emploie pas simultanément le circuit de combustible pour l'évacuation de la chaleur. Le refroidissement se fait plutôt au moyen d'un circuit de refroidissement séparé se trouvant en contact thermique étroit avec la conduite de combustible liquide. Ceci permet d'exploiter pleinement les avantages du combustible liquide tout en optimisant le circuit de refroidissement. Ainsi, les mesures de sécurité peuvent être simplifiées considérablement. Ce réacteur présente par ailleurs une économie neutronique optimisée et est ainsi en mesure de désactiver ses propres produits de fission à longue durée de vie de telle manière que seuls des déchets radiotoxiques à courte durée de vie doivent être stockés. L'excès neutronique permet par ailleurs de désactiver des constituants radiotoxiques à longue durée de vie issus d'éléments combustibles brûlés de réacteurs à eau légère contemporains ou de produire des radiosiotopes médicaux.
