Gabon natural analogues

Bangombe, Oklo natural reactors, Gabon Natural Analogue 0.25 — 25-500 Presence of a weathered zone. Groundwater chemistry controlled by the Fe " /Fe(OH)3 equilibria. Fluids are not enriched in CO2. [Pg.174]

The Oklo natural reactors in Gabon are the best natural analogues for assessing the geological behaviour of fission products and actinides (see also Gauthier-Lafaye et al. 2004). Elements that were compatible with the U ore structure were retained, whereas elements that... [Pg.82]

One namral analogue for geological disposal of nuclear waste is at a site near Oklo, Gabon, West Africa. About 2 billion yr ago, a uranium ore body sustained fission for a period of about 100,000 yr. Most of the fission and activation products from this namral reactor migrated only a short distance from the fission sites, which gives natural supporting evidence for the potential of radionuclide transport from underground waste disposal facilities. [Pg.97]
