An ancient nuclear reactor that was churning away 2 billion years ago sounds like a fabricated myth. WUZ. Uranium is the primary element used to generate energy via nuclear fission. Rather they were the products of the decay of radioactive isotopes of iodine, which in turn were formed from radioactive tellurium and so forth, according to a well-known sequence of nuclear reactions that gives rise to stable xenon. Physicists from several countries met in Gabon to find out what was happening at the Oklo mine and found that underground, there was a nuclear reactor that appeared to be natural. Gauthier-Lafaye et al., 1997. Carbonaceous substances in Oklo reactorsAnologue for permanent deep geologic disposal of anthropogenic nuclear waste. Researchers have labeled the Nuclear Reactor at Okloa Natural Nuclear Reactor, but the truth goes far beyond our comprehension.A few researchers engaged in the testing of the Nuclear reactor concluded that the minerals had been enriched in the distant past, around 1.8 billion years ago to produce a chain reaction naturally.They also discovered that water had been used to lessen the reaction in the same manner that modern nuclear reactors cool down using graphite-cadmium shafts preventing the reactor from going into a critical state and exploding. And they certainly can, though not necessarily about reactor design. The answer came only when someone recalled a prediction published 19 years earlier. Natural nuclear fission reactors: Time constraints for occurrence and their relation to uranium and manganese deposits and to the evolution of the atmosphere. The Oklo reactor we studied had switched on for 30 minutes and off for at least 2.5 hours. Create your free account or Sign in to continue. To analyze the isotopic composition of xenon requires a mass spectrometer, an instrument that can separate atoms according to their atomic weight. After my colleagues and I had worked out in a general way how the observed set of xenon isotopes was created inside the aluminum phosphate grains, we attempted to model the process mathematically. However, uranium solubility is a little tricky. These neutrons can then happily shoot towards other atoms and continue the chain reaction. The energy produced by these natural nuclear reactors was modest. Two billion years ago parts of an African uranium deposit spontaneously underwent nuclear fission. If you were to extract it from the Earth's crust, or from rocks from the moon or in meteorites, that's what you would find. Scientists found an old nuclear reactor in an African mine. "Then the Lord rained down fire and tar from heaven upon Sodom and Gomorrah, and utterly destroyed them." Genesis 19:24.

This neutron fuses with a Uranium 235, and together they combine to form Uranium 236, which is unstable. Thus, two billion years ago in Gabon two of the four conditions for the development of a natural nuclear fission reactor were met: there were significant concentrations of uranium, and this uranium still contained a significant amount of highly-fissionable uranium-235. There were also no significant quantities of neutron-absorbing elements to inhibit the self-sustaining fission reaction. Incredibly, for a large nuclear reactor like this, the thermal impact on the environment was limited to just 40 meters on thesides. THE SCIENTISTS. About the Author: Evelyn Mervine is currently pursuing her PhD in Marine Geology & Geophysics in the joint program between MIT and Woods Hole Oceanographic Institution. Nuclear power was invented in Africa 2 billion years ago. When the Earth was first formed, uranium-235 comprised more than 30% of uranium [Figure 3]. Which again may have all occurred naturally but to many researchers, this seems more like it was designed. Of course, we first needed to decide where exactly to aim the laser beam. The ancient nuclear reactors use surface water and groundwater to modulate and reflect sequenced fission neutrons, its operation is much more advanced than that of modern nuclear reactors. Maybe it's because the term reactor usually implies a manmade structure. In: Uranium-Series Geochemistry. But it did not work as it should due to a lack of maintenance. Physicists confirmed the basic idea that natural fission reactions were responsible for the depletion in uranium 235 at Oklo quite soon after the anomalous uranium was discovered. During a routine isotopic measurement of uranium ore from Gabon, the French noticed something very strange: the uranium ore did not have a uranium-235 content of 0.720%. According to studies, this ancient nuclear reactor was several kilometers long. The isotopic distribution of uranium is remarkably uniform in Earths crust, so all uranium ore mined today contains about 0.720% uranium-235. There are four conditions which must be met in order for a stable natural nuclear reactor to develop: 1. Subscribe today for ourWeekly Newsletterin your inbox! Nuclear fission is when an atom breaks apart into smaller atoms, usually releasing energy in the process. So, in theory, an ancient (billions of years old) uranium deposit could have spontaneously developed a self-sustaining nuclear fission, assuming the uranium was concentrated enough, there was a substance (probably water) to act as a moderator, and there were not significant amounts of neutron-absorbing elements nearby. 14. So, it would have been very difficult to concentrate a significant amount of uranium since there was no oxygen to transform uranium into its soluble forms. This increase of atmospheric oxygen allowed uranium to become mobile and to be concentrated through hydrothermal circulation. Shortly after this astonishing discovery, physicists from around the world studied the evidence for these natural nuclear reactors and came together to share their work on the Oklo phenomenon at a special 1975 conference held in Libreville, the capital of Gabon. But before using his apparatus, we had to extract the xenon from our sample. In an area of stable geology, they found a number of deposits, all oddly . This conclusion may very well have furrowed some brows since there are three very specific conditions that a reactor needs to churn out energy continuously. The only difference was that it was way more advanced than the modern nuclear reactor and could use 100-percent pure water to generate energy, which is still impossible by today's . The nuclear reactors are found in the FA sandstone layer. The lower part of this sandstone layer originally contained many small bits of uranium-bearing minerals (monazite, thorite, probably uraninite). Kuroda pointed out that the conditions necessary for a natural nuclear reactor to develop could have been present in ancient uranium deposits. The uranium must contain significant amount of fissionable uranium-235. After a time, the water would get so hot that it would start to boil off. But even if nature could miraculously create a similar process on a microscopic scale, the mix of xenon isotopes in the aluminum phosphate grains we studied would have been different from what we found. ALEX P. MESHIK began his study of physics at St. Petersburg State University in Russia. That small difference was enough to alert French scientists that there was something very strange going on with the minerals. But in this case, the reactor is a region of natural uranium within the Earth's crust, found in Okla, Gabon. This is because the concentration of uranium-235 is too small (only 0.720% of uranium, as I mentioned above) for a self-sustaining fission reaction to be sustained. All of this provided the perfect recipe for a natural nuclear fission reactor. 3 min read. Shortly thereafter, Paul K. Kuroda, a chemist from the University of Arkansas, calculated what it would take for a uraniumore body spontaneously to undergo selfsustained fission. The nuclear fission began, moderated by water, and continued until all available water boiled away as a result of nuclear heat. Several experts discussed the great Nuclear Reactor at Oklo, stating that at no time in the geologically estimated history of the Oklo deposits was the uranium sufficiently abundant Uranium 235 for a natural nuclear reaction tohappen. BREAKING NEWS ! Finally, after millions of years, and well after the nuclear chain reactions terminated, xenon 129 formed. What was fund in Oklo surprised everyone gathered there, the site where the uranium originated from is an advanced subterranean nuclear reactor that goes well beyond the capabilities of our present scientific knowledge? The xenon did not simply migrate from one set of preexisting minerals to anotherit is unlikely that aluminum phosphate minerals were present before the Oklo reactors began operating. After scratching their head for weeks, researchers at the French Atomic Energy Commission (CEA) came to the conclusion that the missing uranium must have gone through a nuclear fission and split into other atoms which was extremely unlikely as this would require some very specific conditions. Nuclear Energy Is as Old as Life Itself. Okay, so everyone is assuming 'ancient Africans' refers to humans, when it really can refer to any (hypothetical) ancient being from Africa, as clearly this is before humans . 2021 BEYOND SCIENCE TV. For weeks, specialists at the French Atomic Energy Commission (CEA) remained perplexed. Remarkably, these grains showed the highest concentration of xenon ever found in any natural material. Possibly because of this periodic on-and-off behavior, the Gabon natural nuclear reactors were extremely stable. Uranium has three isotopes: uranium-238, uranium-235, and uranium-234. The energy produced by nuclear fission is generally used to heat water and produce steam, which turns large turbines that produce electricity. This is something considered as a holy grail of atomic science. The natural reactor must have annoyed nuclear scientists: The first nuclear reactor to produce electricity started up in 1951, and this only produced a trivial amount of energy. Figure taken from Mossman et al., 2008. Ancient Nuclear Reactor found in Africa believed to be 2 billion years old. These oxidizing waters dissolved the uranium-bearing minerals and concentrated the uranium in several deposits towards the top of the sandstone layer. Undeniable Proof that we are Not the First Species of this Planet . In 1972, a worker at a Reactor fuel processing plant observed something strange in a routine analysis of uranium extracted from a mineral source from Africa. Because there was really no other possible explanations for it. As a result of this fission, fast neutrons are produced. The first being the size of the uranium deposit needs to exceed the length that fission-inducing neutrons travel. The views expressed are those of the author and are not necessarily those of Scientific American. Some university science faculty and for the use of inclusive language and terminology: administrators are resistant to making . https://www.youtube.com/watch?v=H9PAxAK6fBk, Scientist concludes death is only an illusion, it is not real, The Nazi Antarctic Fortress: Base 211 and Operation Highjump, Rare, ancient maps show how thousands of years ago, an advanced civilization mapped the Earth, Secret Space Program Whistleblower claims Humans are on Mars since 70s. Xenon possesses nine stable isotopes, produced in various proportions by different nuclear processes. These ancient "batteries" were found by German archaeologist Wilhelm Konig in 1938 just outside of Baghdad, Iraq. An ancient nuclear reactor, which is estimated to be around 2 billion years old, was discovered in 1972 by French physicist Francis Perrin in Gabon, West Africa. Discover world-changing science. Thanks for reading Scientific American. The incredible features of the Great Pyramid of Egypt. Uranium enrichment plantsindustrial facilities that require considerable skill to construct take advantage of this property to produce reactor fuel. For three decades, the two-billion-year old Oklo phenomenon has been used to argue against _ having changed. They hate you and want to impoverish/control/starve you via Great Reset. She can be found on Twitter as @GeoEvelyn. All of this, in nature. The reactor eventually slowed to a stop, leaving only a few traces behind that it ever existedincluding the enigma of the "missing uranium. Introduction to U-series Geochemistry. Danilo Russo/Flickr (CC BY-ND 2.0), Greenland's Ice Sheet Hasnt Been This Hot For At Least 1,000 Years, New Anti-Aging Pills For Dogs Hope To Make Them Live Longer. Notably, in a 1956 paper Paul Kuroda theorized the conditions under which nuclear fission could spontaneously develop and be sustained. 19: 1-13 Two factors came together, 1.7 billion years ago, to create a natural . The second epiphany was that the extracted gas had a significantly different isotopic makeup from what is usually produced in nuclear reactors. 2 BILLION Year Old NUCLEAR REACTOR Discovered in Africa, 10 Things That Will Happen if Humans Suddenly DISAPPEARED, 2,400-Year-Old Statues of the Goddess of Hygiene Rescued from Rubble of Ancient Medicine City, Bizarre Facts About Ancient History And Ancient Peoples, The Middle Ages In Europe And Around The World, Italys Most-wanted Mafia Boss, Matteo Messina Denaro Arrested After 30 Years On The Run. But last year Steven K. Lamoreaux and Justin R. Torgerson of Los Alamos National Laboratory drew on Oklo to posit that this constant has, in fact, varied significantly (and, strangely enough, in the opposite sense from what others have recently proposed). Israel's security concerns increased in 1978 as France decided to provide highly enriched uranium as well, and increased still further in 1979 . Create your free account or Sign in to continue. The ability to moderate the reaction means that once the reaction was commenced, it was possible to leverage the output power in a controlled manner, with the capacity to prevent disastrous explosions or the release of the energy at a single time. Dr. Glenn T. Seaborg, former head of the United States Atomic Energy Commission and Nobel Prize winner for his work in regard to the synthesis of heavy elements, mentioned that conditions must be correct for uranium to burn in a reaction.For example, the water involved in the nuclear reaction must be crude.Even a few particles per million of contaminants can poison the reaction, bringing it to a stop.The problem is that no pure water exists naturally anywhere in the world. The natural nuclear fission reactors in Gabon are unique to date, no additional natural nuclear reactors have been discovered. Evidence Exists For Prehistoric Nuclear War Ancient Indian Epics, especially the Mahabharata, document apparent pre-historic nuclear devastation and destruction, that is being verified by diverse scholars. Eventually, sixteen natural nuclear reactors were discovered in uranium mines at Oklo [Figure 1]. Each side was in a mad race to harness its destructive power first. "Hearst Magazines and Yahoo may earn commission or revenue on some items through the links below." A small nuclear reactor in France found no evidence of sterile neutrinos, the ever elusive fourth neutrino. In order to increase the efficiency of the nuclear chain reactions, uranium-235 is artificially enriched to approximately 3% before uranium is used as a fuel in nuclear power plants. Scientists are still working to understand the Gabon reactors, but over the past forty years, they have managed to tease out some of the details of how these nuclear reactors operated and were preserved in the geologic record. When these deposits were formed in the distant past, due to the slowness of the radioactive decay of U-235, the fissionable material would have constituted only 3 percent of the total deposits something too low mathematically speaking for a nuclear reaction to take place. Further analyses showed that ore from at least one part of the mine was far short on uranium 235: some 200 kilograms appeared to be missing enough to make half a dozen or so nuclear bombs. Archaeologists found the Oklo nuclear plant in Africa that is said to be at least 2 billion years old. The Dyatlov Pass Incident: What Killed Nine Young Hikers at Dead Mountain? Ancient nuclear reactor found in African country. There are several types of power reactors, but only one, the light-water reactor, is widely used. These zones were all identified decades ago. CIA/MOSSAD/ISI is owned and operated by the Rothschild-Rockefeller Cartel. 4 days ago. As the atoms started to split, they released neutrons as well as energy. It had seemingly lost a large portion of the xenon 136 and 134 that would certainly have been created from fission, whereas the lighter varieties of the element were modified to a lesser extent. Researchers believe that this ancient nuclear reactor is around 1.8 billion years old and operated for at least 500,000 years in the distant past. Incredibly, compared with this massive nuclear reactor, our modern-day nuclear reactors are not comparable both in design and functionality. 2005. Today even the most massive and concentrated uranium deposit cannot become a nuclear reactor, because the uranium 235 concentration, at less than 1 percent, is just too low. Natures Operating Schedule The reactions could not begin again until new water infiltrated the reactor. Elsewhere in the earths crust, on the moon and even in meteorites, we can find uranium 235 atoms that make up only 0.720 percent of the total. x. Whats the Significance of the Worldwide Monoliths? They also found that water had been used to moderate the reaction in the same way that modern nuclear reactors cool down using graphite-cadium shafts preventing the reactor from going into critical state and exploding. Two billion years ago parts of an African uranium deposit spontaneously underwent nuclear fission. However, when uranium is in its oxidized form (U6+), uranium easily forms soluble complexes. If you look around, there are clues found all around the world from the Great Pyramids of Egypt to the Sacsayhuaman ruins in Peru that point to the possibility that advanced prehistoric civilizations may have existed on this planet tens of thousands or even millions of years ago and in this article we will talk about one of the most intriguing finds, an ancient nuclear reactor. Scientists Solve Major Nuclear Reactor MysteryIsrael Sebastian - Getty Images. by Ancient Code Team. Scientists who were sent to investigate the site concluded that This nuclear reactor came into being 1.8 billion years ago, and was operational for about 500 thousand years. chemistry of the noble gases xenon and krypton. Other uranium deposits (which did not host natural nuclear reactors) are found at Boyindzi, Oklobondo, and Mikouloungou. 25: 781-782. The ancient reactor consisted of five hundred tons of utilized uranium ore in six different areas. The more important lessons may be about how to handle nuclear waste. None of the xenon isotopes we measured were the direct result of uranium fission. In 1972, a worker at a Reactor fuel processing plant observed . Oklo - Ancient African Nuclear Reactor. This requirement helps to ensure that the neutrons given off by one fissioning nucleus are absorbed by another before escaping from the uranium vein. This exercise revealed much about the timing of reactor operation, with all xenon isotopes providing pretty much the same answer. This on-and-off behavior of the reactors probably operated over a timescale of a few hours, analogous to the way in which geysers erupt periodically as a result of groundwater recharge. Why is it that these parts of the deposit did not explode and destroy themselves right after nuclear chain reactions began? The preservation of the Gabon reactors is a result of two factors: the long-term stability of the African craton, and the isolation of the uranium deposits from oxidizing groundwater. Even a few parts per million of contaminant will poison the reaction, bringing it to a halt. We applied this technique to many tiny spots on our lone available fragment of Oklo rock, only one millimeter thick and four millimeters across. . Proof in the Light Elements Scientists appear to have unraveled the mystery of uranium ore found at a mine in Oklo . The ancient nuclear reactors use surface water and groundwater to modulate and reflect sequenced fission neutrons, its operation is much more advanced than that of modern nuclear reactors. Such a natural reactor was discovered sixteen years later, in 1972, in Gabon. I was fortunate to have access to an extremely accurate xenon mass spectrometer, one built by my Washington colleague Charles M. Hohenberg. Xenon is extremely rare, which allows scientists to use it to detect and trace nuclear reactions, even those that occurred in primitive meteorites before the solar system came into existence. At the Oklo mine in Gabon, West Africa, in 1972, a company from France was searching for Uranium to fuel their nuclear power plants. The pile of rock in the ground in Okla, on the other hand, creatednuclear power around2 billion years ago! Scientists who were sent to investigate the site concluded that This nuclear reactor came into being 1.8 billion years ago, and was operational for about 500 thousand years. note: thanks to readers for pointing two errors, now fixed: it is ten million, not one million lightbulbs that a manmade reactor can power, and it is nuclear, not chemical energy that is released in it. Further, at the Gabon reactors many of the radioactive products of the nuclear fission have been safely contained for two billion years, providing evidence that long-term geologic storage of nuclear waste is feasible. There must not be significant amounts of neutron-absorbing elements (such as silver or boron), which would inhibit a self-sustaining nuclear reaction, in the vicinity of the uranium. When uranium is in its reduced form (U4+), uranium tends to form very stable compounds that are not easily brought into solution. Required fields are marked *. Per . NUCLEAR REACTOR OPERATIONAL AFTER 34 YEARS, START OF NUCLEAR POWERED - PHILIPPINES 2022 Update: Latest development regards to Nuclear Energy in the Philippines, reviving the Bataan Nuclear Power Plant made possible by the Duterte Administration. Amazingly, the actual conditions that prevailed two billion years ago in what researchers eventually determined to be 16 separate areas within the Oklo and adjacent Okelobondo uranium mines were very close to what Kuroda outlined. The second condition is a source of neutrons. Sixteen years later, in 1972, just such a natural nuclear reactor was discovered in Gabon. Even a few parts per million of any contaminant will poison the reaction, bringing it to a halt. Take a look at the complete line-up of bloggers at our brand new blog network. Her interviews with her father became extremely popular and were distributed far and wide on the internet. But only recently did my colleagues and I finally clarify major details of what exactly went on inside one of those ancient reactors. However new research has definitively ruled out that this strange measurement . Precambrian Research, vol. Being a noble gas, it resists chemical bonding with other elements and is thus easy to purify for isotopic analysis. No human-made reactor can be compared to what the French scientists found at the Oklo mining site. 52: 1-22. Uranium is naturally radioactive, and the conditions in this rocky areahappened to be just right to cook up some nuclear reactions. This watery cycle probably continued for hundreds of thousandsof years. AmINotAlpharius 1 min. The proportion of uranium-235 relative to uranium-238 has been changing because isotopes of uranium are radioactive and decay to other elements over time. The Workings of an Ancient Nuclear Reactor. So was this ancient reactor just a natural marvel as many publications claim or could it have been constructed by a bygone civilization millions of years ago.

These conditions are very similar to the conditions under which nuclear reactions are sustained in manmade nuclear reactors. Geological Society of America Memoirs, vol. 120, no. 2.2k views. Our first surprise was the location of the xenon. Water was able to percolate into the permeable sandstone containing the uranium deposits, and this water acted as the neutron moderator. TrueRignak 1 min. However, uranium-238 decays at a much slower rate than uranium-235, so uranium-235 has become more and more depleted (relative to uranium-238) over the Earths 4.54 billion year history.
