Title
(DE) DUAL FLUID REAKTOR - VARIANTE MIT FLÜSSIGMETALLSPALTSTOFF (DFR/ m)
(EN) DUAL FLUID REACTOR – VARIANT WITH LIQUID METAL FISSIONABLE MATERIAL (DFR/ M)
(FR) RÉACTEUR À FLUIDE DUAL - VARIANTE AVEC MATIÈRE FISSILE MÉTALLIQUE LIQUIDE (DFR/M)
Abstract
(DE)
Die Erfindung betrifft einen nach dem Dual Fluid Prinzip arbeitenden nuklearen Reaktor mit einem speziellen Flüssigmetallspaltstoffgemisch als Flüssigbrennstoff in der Flüssigbrennstoffleitung, das einen hohen Anteil an Aktinoiden, vorzugsweise 69 % und höher besitzt. Die Metalle sind bevorzugt ausgewählt aus Chrom (Cr), Mangan (Mn) und Eisen (Fe). Bevorzugte Aktinoide sind ausgewählt aus Thorium (Th), Uran (U) und Plutonium (Pu). Die Gemische und entstehende Multikomponentenlegierungen müssen nicht notwendigerweise ein Eutektikum sein.
(EN)
The invention relates to a nuclear reactor operating according to the dual fluid principle and having a special liquid metal fissionable material mixture as liquid fuel in the liquid fuel line, said mixture having a high proportion of actinides, preferably 69% and higher. The metals are preferably selected from chromium (Cr), manganese (Mn) and iron (Fe). Preferred actinides are selected from thorium (Th), uranium (U) and plutonium (Pu). The mixtures and resulting multicomponent alloys do not necessarily have to be a eutectic.
(FR)
L’invention concerne un réacteur nucléaire fonctionnant selon le principe du fluide dual avec un mélange spécial de matières fissiles métalliques liquides qui est utilisé comme combustible liquide dans la conduite de combustible liquide et qui comporte une forte proportion d’actinides, de préférence 69 % et plus. Les métaux sont de préférence choisis parmi le chrome (Cr), le manganèse (Mn) et le fer (Fe). Les actinides préférés sont choisis parmi le thorium (Th), l’uranium (U) et le plutonium (Pu). Les mélanges et les alliages multi-composants résultants ne doivent pas nécessairement être eutectiques.
