  • Where Does Uranium Come From? Nuclear Energy Institute

    Ore mined from openpit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, dried and packaged. A conversion plant removes impurities from yellowcake and chemically converts the material to uranium hexafluoride.

    Conventional nuclear reactors only use about 3 to 4 percent of uranium's accessible energy. The energy left behind is what makes conventional nuclear waste—radioactive for hundreds of thousands of years—so dangerous. Extracting more of the available energy reduces the radioactive lifetime of the waste.
