Natural chain reaction in the Oklo mine in Gabon
Creators
Description
An isotopic analysis of a sample of uranium ore from the Oklo mine in Gabon showed a significantly reduced content of 235U (down to 0.296% 235U). The isotopic composition of neodymium (shown), lead, rubidium, ruthenium, strontium, krypton, and xenon proved that a chain reaction took place in the ore deposit approximately 1,800 million years ago. The reaction proceeded for about 10 to 70 thousand years. About 200 kg of 235U has undergone fission and the burn-up amounted to 25,000 MWd/t. (B.S.)
