Oklo Mine: Natural Nuclear Reactors in Gabon, West Africa 1972

08 Jun

Oklo Mine, Gabon, AfricaI recently learned about the existence of a natural nuclear reactor in Oklo (Gabon – see Image), from a physics podcast and was amazed to learn that this reactor was active until about 1.5 billion years ago. It was discovered in 1972 by French physicist Francis Perrin.

“It came as a great surprise to most, therefore, when, in 1972, French physicist Francis Perrin declared that nature had beaten humans to the punch by creating the world’s first nuclear reactors. Indeed, he argued, nature had a two-billion-year head start. Fifteen natural fission reactors have been found in three different ore deposits at the Oklo mine in Gabon, West Africa. These are collectively known as the Oklo Fossil Reactors.”

    Well… There you go, once again it is proven that though man can make affects on nature it still has the ability to do it, itself. Hmm Global warming, Ozone holes and now nuclear reactors. Life it circular and we are just along for the ride.
