Not true. Uranium is an extremely common element. It's found throughout the earths crust and in high concentrations in seawater. Currently, we only mine the easy to get stuff. In 100 years or so, we may need to extract uranium from seawater at an increased cost. It is inconceivable that we could run out of uranium.
