The Natural Nuclear Reactor in Gabon
The Natural Nuclear Reactor in Gabon
In 1972, scientists discovered an incredible phenomenon in Gabon, Africa—a natural nuclear reactor. It is located in the Oklo region and proves that two billion years ago, a controlled nuclear reaction took place there, similar to those used in today’s nuclear power plants.
How Could a Natural Nuclear Reactor Form?
The Oklo region contains large amounts of uranium-235, an element used for nuclear energy production. Billions of years ago, uranium concentration was higher than today. Under the right conditions, with the presence of water, a chain reaction started and produced energy for about 500,000 years.
A Scientific Mystery
Scientists were surprised by several facts:
The nuclear waste remained in place and did not spread, unlike modern nuclear reactors, which still struggle with waste disposal.
The conditions for the formation of a natural nuclear reactor had to be extremely precise, which is very rare in nature.
An Alien Origin?
Some people believe that the Oklo reactor was not formed naturally but was created by an advanced civilization—possibly even aliens. Scientists reject this theory, but the mystery of the Oklo reactor continues to fascinate the world.
