Natural Nuclear Reactor

The region of uranium mines in Oklo, Gabon West Africa is examined in detail and shown that a natural nuclear reactor operated there 2 billion years ago. How this was possible is explained in terms of the different half-lives and the presence of an underground river. What this means for nuclear waste storage and its long-term effects.

    Some more detail on this can be found in James Mahaffey's excellent book _Atomic Awakening:_ ---------- The uranium had been sitting there for billions of years when something changed and groundwater started leaking into the underground deposit. The water acted as a moderator, slowing neutrons down to fission-producing energies, and the reactors fired up. The reactors operated in pulse mode, with the water being heated to a few hundred degrees Celsius, boiling away, and temporarily shutting down for cool-off. The operating interval was about 2 hours and 30 minutes. The power production continued for a few hundred thousand years, which, needless to say, is an admirable and unprecedented working life for a nuclear machine. They produced power at a rate of 100 kilowatts in the form of heat, made 11,907 pounds of radioactive waste, and 3,307 pounds of plutonium. The water-logged, sandstone/shale structure of the Oklo mines is hardly an ideal geologic depository for nuclear waste. We would never consider using such a place for long-term storage of radioactive fission by-products. Yet, in 1.5 billion years the toxic remnants of the Oklo reactor operations had barely migrated a few centimeters. Nothing poisonous had made its way into the ground-water, there was no evidence of biological harm, and the highly radioactive fission products had remained in place until they decayed into stable end-products. Mother Nature had effectively built a power-reactor cluster, pulled the controls, and ran the thing for a long time without causing any harm.

The whole cycle was about 3h long, with 30 minutes of reactions that lead to water evaporation, and stopped the reactor, which allowed water to fill it up and cool down, which started reactions again, and the cycle repeated.

    Excellent! The best presentation I've ever seen regarding the topic! Wow, impressive and will use as an example to re-enforce the paradigm of thinking along with recycling/concentrating waste, nucleosynthesis and advanced areas of opportunity to remediate waste into more valuable elements.

    @@oldgeezerproductions Sure, if you are finished being pedantic, let me rephrase. I haven't watched nor read anything from that person other than this exact video. There is nothing stating his opinion on the matter of nuclear waste disposal in this video. So if you are not talking about this video why comment here ? I'm sure there is other video actually containing his opinion or as you said "his hypothesis (not even a theory)" The only conclusion this video has is "Given the quite small observed radioisotopes migration on a natural nuclear reactor occasionally washed by water over a geological timescale , it is until the observation are proven false, possible to imagine storing nuclear wastes over geological timescale." I don't see anything wrong with that statement. Here he doesn't state anything more than that. I don't see how his opinion (not part of this video) would change that. As I said, the only person stating anything "unwarranted" is you. Whatever wrong opinion you think he may has, it would still not be "unwarranted" either. And that would hold true until the findings at Oklo are proven to be misunderstood all along.

The heat comes from the natural geothermal temperature gradient as groundwater percolates to a sufficient depth. However, the terrestrial heat flow is due in part to the heat generated by the decay of the principal radionuclides uranium, thorium and potassium. that was known over a hundred years ago as studies of heatflow on granites was shown to be caused by their content of U, Th and K.

    Okay, this is great video, maybe one of the best on explaining Oklo that I could find. And it's a great concept of "the perfect accidental circumstance" has occurred for the reaction to happen. But my question is, and I'm not a nuclear physicist so if my question is stupid please bee gentle, but my question is, is it really possible that this happened accidentally? One of the articles I read about Oklo stated that yes all of these ores and the underground rivers are all present, but these are not the correct circumstances for nuclear fission to happen. One of the biggest arguments is that the water has to be pure (I believe we use distilled water in reactors) for the reaction to happen? Are there limitations in nature that make this process impossible without outside manipulation? I'm not saying aliens btw, just a question.

    Why would the water have to be pure? Even in say salt water, or muddy water there is a lot of water to slow down the neutrons. But it is the hydrogen in water that slow down the neutrons, so it is not the water, it is the hydrogen atoms. Presumably there was no sign of tampering in these geological structures.
