About 2 billion years ago, at least 16 natural nuclear reactors achieved criticality in a high-grade deposit of uranium ore (a 17 th was in the Bangombe deposit 30 km away). Each operated intermittently at about 20 kW thermal, the reaction ceasing whenever the water turned to steam so that it ceased to function as moderator.
As most of the mines use overburden as backfilling material for mined out areas, ground water contamination may also result from leaching activities, which may have Spartan …
