Uranium processing - Canadian Nuclear Association

The uranium conversion process for CANDU heavy water reactors involves converting UO 3 to uranium dioxide (UO 2). This takes place in Port Hope, Ontario, home to Canada''s only uranium conversion facility. Nitric acid and ammonia are added to UO 3, which is then fed into a special kiln operating with a reduction atmosphere.

NRC: Uranium Enrichment

The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.
