2 - Governing Uranium

B efore 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 (UO 2) or hexafluoride (UF 6).The transportation process is extensive, presenting a host of formidable yet manageable security risks.
