Splitting uranium atoms—the fission process—creates heat to boil the water. Before its use in a reactor, uranium must undergo four major processing steps to convert it from its raw state to a usable fuel source: mining and milling, conversion, enrichment, and fuel fabrication. The resulting pellets are loaded into fuel rods.

Wastes from mining milling. In most respects, conventional mining of uranium is the same as mining any other metalliferous ore, and wellestablished environmental constraints apply in order to avoid any offsite pollution. From open cut mining, there are substantial volumes of barren rock and overburden waste.

Open pit mining is a surface mining technique that is done by removing the top soil and rocks underneath to excavate the uranium ore. The debris is recovered and transported to the milling facilities. This type of mining is usually used if the uranium ores are located above shallow deposits. This form of mining is used for a high grade ore.

Radiation Facts. Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.
