  • Method and apparatus for reducing uranium trioxide
    Patent number: 7029633
    Abstract: Uranium trioxide is reduced to uranium dioxide using microwave radiation or radiofrequency radiation directed in such a way that the radiation encounters an interface between uranium trioxide and the uranium-containing reduction product without first having passed through that product. By this method, and also using a reducing gas, it is possible to obtain UO2 with an O:U ratio less than 2.04:1.
    Type: Grant
    Filed: March 1, 2001
    Date of Patent: April 18, 2006
    Assignee: Cameco Corporation
