The Oklo, Gabon, Natural Fission Reactor
Papers and Reports
 |
The natural nuclear reactor found at Oklo, Gabon, is the best known of this phenomena. Many excellant descriptions of it are to be found across the internet, so I will not attempt to repeat them here.
A naturally occurring nuclear chain reaction is no longer possible on earth, as the neutrons released by the chain reaction cannot be moderated sufficiently, and a sufficient concentration of uranium maintained, at a U-235 enrichment of 0.7%. Millions of years ago, before radioactive decay reduced its concentration relative to U-238, natural fission reactors were possible.
What is presented here is a collection of research reports that touch on the Oklo reactor. Some are no longer freely available to the public after the National Laboratories closed their electronic libraries to the public after 9/11. None of the research is in any way restricted at the time of their download. They make facinating reading, and many require a bit of thought to be understood, being written and meant for people with advanced degrees.
If you have similar reports in electronic format, and wish to share them with others, please contact me [psch(a)optonline.net] and I will add them to this collection. You will be listed as the donar of the paper. I ask that the papers be available for free public distribution and not be classified, or have a copyright whose holder does not grant the right to free distribution.
