All, just a bit of further explanation so people don't come up with misconceptions in trivial pursuit games about radioactive jargon or facts,  there cannot be "billions" of pounds of UF6 (uranium hexaflouride which is a gas) in the world much less in Oak Ridge.  I'm assuming Bob is using "billions" as a substitute word for large amounts.  Even so, that is a stretch.  UF6 is the gaseous uranium state used in a gaseous diffusion set-up to enrich for bomb grade uranium at Oak Ridge for WWII and (now in other places in the world????).  Depleted gas is reduced to metal state simply to reduce the volume of the gas.  There for sure is depleted U-238 around with the halting of the production of Pu-239 actually from feeder U-238.  Or so says a nuclear physicist/engineer who has made his way around Oak Ridge, Hanford and Los Alamos and many other nuclear sites over the last 40 years.
