Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey 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 isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and 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 is the only naturally occurring fissile isotope, which makes it widely used in nuclear power plants and nuclear weapons. However, because of the tiny amounts found in nature, uranium needs to undergo enrichment so that enough uranium-235 is present. 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 studied for future industrial use in nuclear technology. 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 lemon yellow to green colors. Uranium glass fluoresces green in ultraviolet light. 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 recently discovered 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 is closely monitored. Since around 2000, plutonium obtained by dismantling cold war era bombs is used as fuel for nuclear reactors.The development and deployment of these nuclear reactors continue on a global base. There is increasing interest in these power plants as they are powerful sources of CO2 free energy. In 2019, 440 nuclear power reactors produced 2586 TWh (billion kWh) of CO2 free electricity worldwide, more than the global installations of solar and wind power combined.

uranium
Uranium is a naturally occurring radioactive chemical element with the symbol U and atomic number 92. Known for its high density, uranium is approximately 70 percent more dense than lead and is weakly radioactive. It is highly common in the Earth's crust, making it about 40 times more common than silver. Uranium is mainly used as fuel in nuclear power plants due to its ability to produce large amounts of energy. Its isotopes, uranium-238 and uranium-235, are used for the production of nuclear weapons and in the generation of commercial electricity, respectively.
Webster Dictionary
Uraniumnoun
an element of the chromium group, found in certain rare minerals, as pitchblende, uranite, etc., and reduced as a heavy, hard, nickel-white metal which is quite permanent. Its yellow oxide is used to impart to glass a delicate greenish-yellow tint which is accompanied by a strong fluorescence, and its black oxide is used as a pigment in porcelain painting. Symbol U. Atomic weight 239.

Examples of Uranium in a Sentence
Today it became known that Great Britain, through the mouth of the deputy head of the Ministry of Defense of this country, announced not only the supply of tanks to Ukraine, but also shells with combined uranium.
Some of the biggest national security questions facing the country run through Piketon and Kemmerer, a Post-Soviet dealAmerican reliance on foreign enriched uranium echoes its competitive disadvantages on microchips and the critical minerals used to make electric batteries — two essential components of the global energy transition.But in the case of uranium enrichment, United States once had an advantage and chose to give it up.In the 1950s, as the nuclear era began in earnest, Piketon became the site of one of two enormous enrichment facilities in the Ohio River Valley region, where a process called gaseous diffusion was used.Meanwhile, the Soviet Union developed centrifuges in a secret program, relying on a team of German physicists and engineers captured toward the end of World War II. Its centrifuges proved to be 20 times as energy efficient as gaseous diffusion. By the end of the Cold War, United States and Russia had roughly equal enrichment capacities, but huge differences in the cost of production.In 1993, Washington and Moscow signed an agreement, dubbed Megatons to Megawatts, in which United States purchased and imported much of Russia’s enormous glut of weapons-grade uranium, which United States then downgraded to use in power plants. This provided the U.S. with cheap fuel and Moscow with cash, and was seen as a de-escalatory gesture.But it also destroyed the profitability of America’s inefficient enrichment facilities, which were eventually shuttered. Then, instead of investing in upgraded centrifuges in United States, successive administrations kept buying from Russia.ImageA mural celebrates Piketon’s gaseous diffusion plant, long ago shuttered, and United States role in the local economy.Credit... Brian Kaiser for The New York TimesImageIn the lobby at Piketon plant, a miniature display of new centrifuges.Credit... Brian Kaiser for The New York TimesThe centrifuge plant in Piketon, operated by Centrus Energy, occupies a corner of the site of the old gaseous diffusion facility. Building United States to United States full potential would create thousands of jobs, according to Centrus Energy. And it could produce the kinds of enriched uranium needed in both current and new-age nuclear plants.Lacking Piketon’s output, plants like TerraPower’s would have to look to foreign producers, like France, that might be a more politically acceptable and reliable supplier than Russia, but would also be more expensive.TerraPower sees itself as integral to phasing out climate-warming fossil fuels in electricity. Its reactor would include a sodium-based battery that would allow the plant to ramp up electricity production on demand, offsetting fluctuations in wind or solar production elsewhere.It is part of the energy transition that coal-country senators like Mr. Manchin and John Barrasso, a Wyoming Republican, are keen to fix as they eye nuclear replacements for lost coal jobs and revenue. While Mr. Manchin in particular has complicated the Biden administration’s efforts to quicken the transition away from fossil fuels, he also pushed back against colleagues, mostly Democrats, who are skeptical of nuclear power’s role in that transition, partly because of the radioactive waste it creates.
Iran has informed the agency that in order to comply with a legal act recently passed by the countrys parliament, the Atomic Energy Organization of Iran intends to produce low-enriched uranium ... up to 20 percent at the Fordo Fuel Enrichment Plant.
If hell uses highly refined uranium and completely pure hydrogen to stoke its fires, the roaring furnaces there will still be too cold for these depraved beings. (Speaking about the leaders of North Korea...) read about it here: http://standfortheright.com/archives/540
It changed my life. Everything is different, these people are the most developed human beings on the planet ... The government, just for their own benefit of uranium and all that other s**t, is destroying them.
