TL;DR Summary
I find it fascinating that there is evidence from a uranium mine in West Africa that there may likely have been a nuclear fission natural reactor that went critical 2 million years ago. More info availble online at PF or somewhere else?
This week I read through the chapter "Energy from the Nucleus" inside the familiar intro physics textbook Halliday, Resnick, Walker. I found it fascinating that there is evidence from a uranium mine in West Africa that there may likely have been a nuclear fission natural reactor that went critical 2 million years ago. Is there more information availble online at PF or somewhere else, where the reader can go deeper?

"Studies have suggested this as a useful natural analogue for nuclear waste disposal." Very interesting!

I recall reading an article on this many years ago (1980s?). It was published in either Scientific American or Smithsonian magazine.
