Short description: Natural nuclear fission reactor discovered in 1972 in the Oklo region of Gabon The natural nuclear fission reactors of Oklo: (1) Nuclear reactor zones. (2) Sandstone. (3) Uranium ore layer. (4) Granite. Oklo Mine (sometimes Oklo Reactor or Oklo Mines), located in Oklo, Gabon on the west coast of Central Africa, is believed to be the only natural nuclear fission reactor. Oklo consists of 16 sites at which self-sustaining nuclear fission reactions are thought to have taken place approximately 1.7 billion years ago, and ran for hundreds of thousands of years. It is estimated to have averaged under 100 kW of thermal power during that time.[1][2][3] ## See also * Geology of Gabon ## References 1. ↑ Meshik, A. P. (November 2005).
