United States uranium position

For the immediate future the magnitude of uranium reserves are far more important than the ultimate size of the resources which may eventually be found. The rate at which new uranium reserves can be found and equipped to feed the lightwater reactors is a vital factor in the transition to more advanced conversion systems such as the Liquid Metal Breeder. The breeders require substantial accumulations of recycled plutonium and uranium in their inventories before they can sustain their growth from the recycling of their own wastes
