Ancient Nuclear Waste Is Teaching Us About Radioactive Storage Today
“To get data on what happens to spent nuclear fuel over long periods of time, researchers are turning to a unique place on Earth — the oldest, and only, known natural nuclear reactor.”
Meet Oklo, the Earth’s Two-billion-year-old only Known Natural Nuclear Reactor
“For such a phenomenon to have happened naturally, these uranium deposits in western Equatorial Africa must have had to contain a critical mass of U-235 to start the reaction. Back in those days, they did. A second contributing factor was that, for a nuclear chain reaction to happen and be maintained, there needed to be a moderator. In this case: water.”
The world’s first and only natural nuclear reactor
“In a singular but well-documented circumstance, scientists have found evidence that naturally occurring fission reactors were created inside three uranium ore deposits in the west African country of Gabon.”
