The Oklo phenomenon as an analogue of radioactive waste disposal A review
The first part of this report gives details of the natural reactions that took place in the Oklo uranium deposit in Gabon. The uranium concentrations (20-70%) which generated the nuclear reactions at Oklo were derived from the total desilication of rich sandstones (with a uranium level from 2-15%). This phenomenon occurred during tectonic actions, but was greatly extended by the nuclear reactions themselves through the convection currents which developed following the generation of heat. The second part presents the information available on the retention or migration of the most interesting fission products at Oklo. An attempt is made to illustrate the relevance of the Oklo experience in predicting the destiny of high activity waste disposed of in stable geological formations.
