  • 2 Governing Uranium

    Before becoming suitable for nuclear energy, producers extract uranium from the ground and process it into uranium ore concentrate (UOC). UOC must then be transported to a facility to be converted to uranium dioxide (UO2) or hexafluoride (UF6). The transportation process is extensive, presenting a host of formidable yet

    But the uranium oxide from the mine is about 99 percent U238. So you need to somehow separate the U235 from the U238 and increase the amount of U235. The process of concentrating the U235 is called enrichment, and centrifuges are a central part of the process. U235 weighs slightly less than U238. By exploiting
