Abstract

Procédé et appareil d'enrichissement et d'augmentation de la concentration de l'eau lourde. L'appareil comprend des moyens pour mettre en contact une source d'eau lourde partiellement enrichie dans une colonne catalytique avec de l'hydrogène gazeux (essentiellement D2 ) provenant d'une cuve d'électrolyse, de façon à enrichir l'eau de la source d'alimentation avec du deutérium prélevé à partir de l'hydrogène gazeux électrolytique, et des moyens pour faire passer l'eau enrichie en deutérium vers la cuve d'électrolyse. Application à l'enrichissement et l'augmentation de la concentration de l'eau lourde.
