How Uranium Becomes Nuclear Fuel
 
05:51
Nuclear technology is constantly in the news. So how exactly do you make nuclear fuel? Special thanks to Life Noggin for animating this video! Check them out: http://www.youtube.com/lifenoggin Read More: Fuel Cycle Facilities http://www.nrc.gov/materials/fuel-cycle-fac.html “The U.S. Nuclear Regulatory Commission (NRC) regulates uranium recovery facilities that mill uranium; fuel cycle facilities that convert, enrich, and fabricate it into fuel for use in nuclear reactors, and deconversion facilities that process the depleted uranium hexafluoride for disposal.” Uranium processing http://www.britannica.com/EBchecked/topic/619232/uranium-processing “Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.” About Nuclear Fuel Cycle https://infcis.iaea.org/NFCIS/About.cshtml “Nuclear Fuel Cycle can be defined as the set of processes to make use of nuclear materials and to return it to normal state. It starts with the mining of unused nuclear materials from the nature and ends with the safe disposal of used nuclear material in the nature.” Nuclear Fuel Processes http://www.nei.org/Knowledge-Center/Nuclear-Fuel-Processes “Nuclear power plants do not burn any fuel. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

Uranium Mining in US and Canada in the 1970s
 
08:51
Physically removing the rock ore generally involves either open-pit mining or underground mining. Milling is the process that removes uranium from the ore, which is mostly obtained in open-pit and underground mines. Once at the mill, the ore is crushed and ground up, and treated with chemical solutions to dissolve the uranium, which is then recovered from the solution. Tailings are the wastes from the millings processes and are stored in mill tailings impoundments, a specially designed waste disposal facility. Since 1979, when uranium mine workers began being diagnosed with lung diseases, such as cancer, regulators have gradually tightened controls and mandated improved uranium mining practices. Recently, officials also have become concerned with the broader impacts of uranium mining on public health and the environment. Workers are directly exposed to the radiation hazards of uranium mines. Uranium mining also releases radon from the ground into the atmosphere. Mines and mining waste can release radionuclides, including radon, and other pollutants to streams, springs, and other bodies of water. Federal and state agencies have established pollutant discharge limits and drinking water standards, and continue to monitor these sites for public safety. Uranium mine waste from operations that closed before the mid-1970s are of particular concern. In many cases, these mines remain unclaimed and the waste is still piled near the mine. Weathering can lead to radioactive dust that is blown by the wind and the seepage of contaminants into the surface and groundwater. There are also cases of unclaimed uranium mine waste being used for house construction, which creates significant radon and radiation hazard for inhabitants. For more information on the hazards of uranium, go to USEPA website http://www.epa.gov/radtown/basic.html . This is clipped from the late 1970's BBC Production, Energy From The Crust, showing uranium mining activities and equipment and including footage from the following uranium mines: Schwartzwalder Mine, Near Boulder, Colorado King Solomon Mine near Uravan, Colorado and the Key Lake Mine in Saskatchewan, Canada.

Inspecting the Nuclear Fuel Cycle
 
05:33
The URENCO uranium enrichment plant at Almelo, Netherlands, enriches uranium for clients worldwide to a maximum licensed enrichment level of 6%. Uranium enrichment is one of the key processes in the nuclear fuel supply chain. After mining and conversion, uranium is enriched to a level that makes it suitable for the fabrication of fuel for types of nuclear power and research reactors. The technology at enrichment plants can also be used to manufacture highly enriched uranium (over 20%) and weapons grade uranium (over 85%). Therefore, there is a risk of nuclear proliferation and facilities of this kind come under IAEA Safeguards Agreements. Through inspections, the IAEA confirms that countries are using nuclear materials or technology for peaceful purposes only. IAEA Safeguards Inspector, Ania Kimberly Kaminski, explains the activities and the purpose of an inspection at the URENCO plant.

Isolation of Uranium Yellowcake from Ore
 
06:43
In this video, uranium is concentrated from its ore through a series of precipitations, which eventually yields a form of yellowcake, uranyl peroxide. Please remember to take proper precautions when working with a radioactive heavy metal such as uranium and its salts. Gloves, eye protection, and a dust mask are necessary. For processing, uranium ore is dissolved into hydrochloric acid, oxidized with bleach, precipitated with ammonia, filtered, leached with carbonate, filtered, neutralized with hydrochloric acid, precipitated with hydrogen peroxide, and filtered. The uranium produced by this procedure could in no way be considered weapons-grade or enriched. The enrichment process requires millions of dollars in investment and is impossible for any entity short of a national government to produce. This uranium maintains the isotopic ratio found within the earth's crust and is actually less radioactive than the ore from which it was processed due to the absence of more radioactive decay products of uranium, such as radium, protactinium, and other unstable nuclei produced by the spontaneous fission of U238. Though ore chemistry varies by locality, this process is generalized for any uranium on an acid-soluble matrix. This process was inspired by and based off of: http://carlwillis.wordpress.com/2008/02/20/uranium-chemistry/

WE DO NOT OWN THE MATERIAL EXCLUSIVELY, BUT HAVE A LICENSE CONTRACT FOR INTERNET STREAMING. If unavailable in your territory, or if you are interested in other license requests (feature movie, television, documentary, commercial...), please contact Javafilms: [email protected] Story The African continent is rapidly developing itself economically. The only bottleneck in this process are readily available resources. Besides money these mainly consist of poor infrastructure and availability of energy, especially electricity. Economically booming countries like for example Uganda still have a lot to gain when a steady supply of power is provided. Nowadays in Uganda the power plants can only cater for roughly 30% of the countries demand and even new hydraulic power projects in the Nile will not solve this problem. Nuclear power therefor seems the most cost effective solution for most of the African nations including Uganda. Western companies such as the French Areva fiercely lobby for more power plants on the continent. But is Atomic Energy the best solution for unstable regimes? And what does Atomic Energy and the mining of uranium mean for the wellbeing and safety of the local population and the environment? Social Interest Ever since the first nuclear reactor was build in Africa in Congo in 1958 there have been safety concerns, cause within the whole process of the production of nuclear energy a lot of things can go wrong, willingly and unwillingly, with possible devastating consequences for people and environment. For instance in 2007 the head of the Congolese research institute was arrested for illegally selling nuclear fuel rods. Also in Niger the highway where the mined uranium is transported on runs through rebel territory associated with Al-Qaida. The war in neighbouring Mali makes this transport even more risky. Besides the risks of fuel rods ending up in the wrong hands the mining of uranium itself poses danger to people and environment as well. Legal and illegal mining operations destroy ecosystems and leave the miners with radiation poisoning . Historical and Political Relevance Nuclear power, the right to enrich uranium and develop the technology to exploit its energy, has always been a difficult point in international politics. In the Cold War the threat mainly came from the war talk and power displays of archenemies the United States and the Soviet Union which both had a gigantic nuclear arsenal. As the cold war ended the threat of a nuclear war declined. However the nuclear disaster in a power plant in Chernobyl a few years earlier proved that the benefits of nuclear power also pose a big potential threat in case of incidents. However, this incident did not stop more countries from starting a nuclear program with a wide range of experiments While in the last decade the interest of the West in Nuclear power seems to decline some new players on the nuclear market, with questionable regimes like Iran and North Korea , are causing much international debate about the right to develop nuclear power. The rapidly developing African continent is in serious need of energy and has always been rich in raw resources to produce energy and is now slowly developing the knowledge to exploit them. The African continent may well be on the verge of a nuclear revolution so the political discussion about the right to use nuclear energy is more relevant than ever. Because not only questionable regimes can pose a potential threat, also war and especially terrorism are extremely dangerous, since it takes a single rocket fired by a single person to blow up a nuclear power plant.

Found Footage Lost 50 Years Ago In Malaysian Nuclear Uranium Mine

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1,000 tons per year are Niger, Russia, Namibia, Uzbekistan, China, the United States and Ukraine. Uranium from mining is used almost entirely as fuel for nuclear power plants. Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. The milling process commonly yields dry powder-form material consisting of natural uranium, "yellowcake," which is sold on the uranium market as U3O8

Uranium ore can also be recovered by the in-situ recovery (ISR) method, given appropriate geological conditions. The ISR method is applicable only to sandstone-hosted uranium deposits located below the water table in a confined aquifer. ISR is a method that leaves the uranium orebody in the ground. The uranium is dissolved in either sulfuric acid or a mildly alkaline solution that is injected into and recovered from the aquifer by means of wells. The uranium-bearing solution is then pumped back up to the surface, leaving the rock undisturbed. Nearly a quarter of the uranium mines use the ISR method. 3d animation by www.mininganimations.com

THE PETRIFIED RIVER  URANIUM MINING IN THE WESTERN USA  75674
 
28:14
Support Our Channel : https://www.patreon.com/PeriscopeFilm Made in 1957 by Union Carbide & Carbon company, PETRIFIED RIVER describes the modern romance of the present-day West in the search for uranium. It shows modern uranium prospecting, including prospecting by airplane, as well as mining in the Colorado Plateau. It also discusses the uses of radioactive isotopes at Oak Ridge National Laboratory. Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable (with half-lives of the 6 naturally known isotopes, uranium-233 to uranium-238, varying between 69 years and 4.5 billion years). The most common isotopes of uranium are uranium-238 (which has 146 neutrons and accounts for almost 99.3% of the uranium found in nature) and uranium-235 (which has 143 neutrons, accounting for 0.7% of the element found naturally). Uranium has the second highest atomic weight of the primordially occurring elements, lighter only than plutonium. Its density is about 70% higher than that of lead, but slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99.2739–99.2752%), uranium-235 (0.7198–0.7202%), and a very small amount of uranium-234 (0.0050–0.0059%). Uranium decays slowly by emitting an alpha particle. The half-life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years,making them useful in dating the age of the Earth. Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. While uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating. Uranium is used as a colorant in uranium glass producing orange-red to lemon yellow hues. It was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. Eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel. Research by Otto Hahn, Lise Meitner, Enrico Fermi and others, such as J. Robert Oppenheimer starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium-239. The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is an ongoing concern for public health and safety.

Iran Starts YellowCake production for Nuclear fuel توليد كيك زرد براي سوخت هسته اي ايران
 
00:37
June 27, 2018 (Persian calendar 1397/4/6) Yellowcake (also called urania) is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and refining methods, depending on the types of ores. Typically, yellowcakes are obtained through the milling and chemical processing of uranium ore forming a coarse powder that has a pungent odor, is insoluble in water, and contains about 80% uranium oxide, which melts at approximately 2880 °C.

Environmental impact of brown coal and uranium mining in East Germany (Documentary, 1991)
 
50:55
In the aftermath of the collapse of the Soviet Union the world became aware of the devastating impact on the environment and on the health of the people by brown coal and uranium mining in the former East Germany and Czechoslovakia. SAG/SDAG Wismut was a uranium mining company in East Germany during the time of the cold war. It produced a total of 230,400 tonnes of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time. It was the largest single producer of uranium ore in the entire sphere of control of the USSR. In 1991 after German reunification it was transformed into the Wismut GmbH company, owned by the Federal Republic of Germany, which is now responsible for the restoration and environmental cleanup of the former mining and milling areas. The head office of SDAG Wismut / Wismut GmbH is in Chemnitz-Siegmar. https://en.wikipedia.org/wiki/Wismut_(mining_company) Original title: Black Triangle A film by Ron Orders © 1991, Licensed by Cinecontact Subscribe to wocomoHISTORY: https://goo.gl/oXDoxY Follow us on Facebook: https://www.facebook.com/wocomo

How to Extract Yellowcake from Uranium Ore (Autunite) at Home
 
07:13
In this video we take a look at an amateur accessible route to obtaining a pure uranium compound of known stoichiometry, which can be used for future experiments. Note: The uranium peroxide can be carefully heated at around 300°C to obtain orange UO3, which dissolves more readily in a variety of acids to produce other desired uranium compounds. Care should be taken to not overheat, or else brown-green U3O8 may form that is difficult to dissolve. Disclaimer: Information presented in this video are for educational purposes only.

Uranium Enrichment from Yellow Cake to Enriched Fuel Grade Material and Storage of Used Nuclear Fuel
 
01:50
Uranium Enrichment from Yellow Cake to Enriched Fuel grade material and Storage of Used Nuclear Fuel - Educational 3D Animated Video Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238U isotope, with 235U only constituting about 0.711% of its weight. 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation.

How carbide inserts are made by Sandvik Coromant
 
06:21
Carbide inserts are used to machine almost everything made of metal. The insert has to withstand extreme heat and force, so it’s made of some of the hardest material in the world. We take you to the Sandvik Coromant's world class insert production facility at Gimo, Sweden to witness how an insert is made. See how it's done! Transcript Almost everything made of metal is machined with an insert. The insert has to withstand extreme heat and force, so it’s made of some of the hardest material in the world. A typical insert is made of 80% tungsten carbide and a metal matrix that binds the hard carbide grains together, where cobalt is the most common. It takes more than two days to produce an insert, so it’s a complicated process. In the material warehouse, row after row of raw material are stacked. The tungsten carbide we use is either recycled, or comes from our own mine in Austria. Cobalt, titanium and all other ingredients come from carefully selected suppliers; each batch meticulously tested in the lab. Some recipes contain very small amounts of selected ingredients that are added by hand. The main ingredients are then automatically dispensed at the different stops along the weigh line. In the milling room the ingredients are milled to the required particle size together with ethanol, water and an organic binder. This process takes from eight to 55 hours, depending on the recipe. The slurry is pumped into a spray drier where hot nitrogen gas is sprayed to evaporate the ethanol and water mixture. When the powder is dry, it consists of spherical granules of identical sizes. A sample is sent to the lab for quality check. Barrels of 100 kilograms of ready-to-press powder arrive at the pressing machine. The binder added in the milling room is the binder that holds the powder together after pressing. Up to 12 tons of pressure are applied, depending on the type of insert. The binder added in the milling room is what holds the powder together after pressing. The process is completely automated. Each insert is weighed and at certain intervals controlled visually by the operator. The pressed inserts are very fragile and need to be hardened in a sintering oven. This process takes about 13 hours at a temperature of approximately 1,500 degrees Celsius. The inserts are sintered into an extremely hard cemented-carbide product, almost as hard as diamond. The organic binder is incinerated and the insert shrinks approximately to half its original size. The excess heat is recycled and used to heat the premises in the winter, and cool them down during summer. The inserts are ground, one by one, in different types of grinding machines to achieve the exact size, geometry and tolerances. As the cemented carbide insert is so hard, a disc with 150 million small industrial diamonds, is used to grind it. The excess carbide is recycled, as well as the oil that is used as cutting fluid. The majority of inserts are coated, either through chemical vapour deposition (CVD) or physical vapour deposition (PVD). Here, we see a PVD-process. The inserts are placed in fixtures... …and put into the oven. The thin layer of coating makes the insert both harder and tougher. This is also where the insert gets its specific colour. Although the insert has been inspected at the lab regularly during the whole process, it’s manually examined again before it’s laser marked and packed. After labelling, the grey boxes are ready to be sent out to manufacturers around the world. When the inserts are worn out, they are returned to Sandvik Coromant for recycling, and the process of making a new insert begins.
