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.
