U-235 in Natural Uranium



Hello All:



Does anyone have any literature/information on the normal variability of 

the U-235 concentration in naturally occurring uranium in ores and soils 

i.e. 0.72% +/- ??.  I understand that the NRC considers depleted uranium 

(DU) as uranium depleted below 0.711% U-235.  Does this then mean that 

natural uranium does not exhibit U-235 levels this low (except in unique 

circumstances such as the Okla natural reactor)?



Thank you.
