Uranium assay, extent of deposit, geometry of deposit, presence or
absence of moderator, and presence or absence of poisons are all
important variables. I can think of no good reason to believe there
should have been more than one [set of] Oklos. After all, there are
many natural wonders which are indeed unique.
