    Commercial nuclear reactors typically use one of two types of fuels. CANDU heavy water reactors are capable of using natural uranium (containing about 0.7 of the fissile isotope U 235) in the form of UO 2 fuel pellets. Light water reactors on the other hand require enriched UO 2 with higher concentrations (between 3 5 ) of U 235.. The uranium conversion process for heavy water reactors

    Uranium processingUranium processingLeaching Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore
