Uranium, an element in chemistry, is one of the world’s rare earth metals. It serves many purposes like forging electricity and reinforcing armor. However, why are these things so important and why not use some other environmentally friendly resource?
Firstly, know that uranium has an atomic number of ninety-two on the periodic table. It is in the actinide series and has the period number seven. It was discovered in 1789 by Martin Klaproth, a German Chemist and he named it after the planet Uranus. It is a silvery-white metal. Uranium is radioactive but it radiates, or decays very slowly. It has no stable isotope however; its most stable isotope is U-238. It has a half-life of 4,468,000,000 years. This is good for it efficiency.
Uranium, unlike coal, is very efficient at power making because of its half-life. Its radioactivity can be harnessed to power many things at once. In fact, one small power plant can power the whole west side of Saint Louis. It isn’t very common, but it isn’t very uncommon. In the earth’s crust, there is about two point seven milligrams per kilogram. There are some risky things about using uranium.
Uranium has its downsides and its upsides. Albeit, uranium is efficient, it is also very dangerous if not handled carefully or disposed properly. In a reactor, a malfunction can occur. If it is not treated quickly and carefully, the reactor can overheat and can have a core meltdown. If the nuclear reactor is inside a city, it can shut down a city for years to come. One example of this is the city of Chernobyl in the northern part of the Ukraine. The power plant had a core meltdown in the year of 1986 and is still radiating radioactivity today. It is possible that mill tailings could have co...

... The end product of the mining and milling stages, or of ISL, is uranium oxide. This is the form in which uranium is sold. The Uranium must undergo a series of ways to convert it into usable fuel. For most reactors, the next step in processing the fuel is to convert the uranium oxide into a gas, uranium hexafluoride, which enables it to be enriched. Enrichment increases the proportion of the uranium-235 isotope from its natural level. This enables greater technical efficiency in reactor design and operation, particularly in larger reactors, and makes for the use of ordinary water as a moderator.
Uranium is very useful in society today. Most of the reasons we don’t use other environmentally friendly resources is because none are as efficient as uranium. It also has its uses after it’s used up like reinforcing armor. This makes it very useful in today’s life.
On top of it being cleaner it is cheaper the mining of uranium is cheaper than the mining of coal
The Nuclear Metals Incorporation or the Starmet Corporation is located on a 2229 Main Street in Concord, Massachusetts. The site produced depleted uranium products for armor piercing ammunition. They also created metal powders for medical applications, photocopiers, and specialty metal products, such as beryllium tubing for aerospace needs. From1958 to 1985, the holding basin that contained all the industries waste such as depleted uranium and copper was unlined, which caused issues.
Before we can analyze the ethical use of DU ammunition, it is important to first establish the technology behind DU and DU weapons. Uranium is one of the heaviest elements found in nature and is emits alpha, beta, and gamma particles. It is 1.7 times denser than lead.12 The half-life of U238 (DU is 99% U238) is 4.5 billion years!13 Uranium byproducts(such as Thorium (Th232)) have even longer half-lives, making uranium an element that gets more radioactive during its own decay process.5 Natural uranium is 99.274% U238, 0.720% U235, and 0.0055% U234.14a Uranium is enriched when its contents of U235 reaches 3.2-3.6% (since U235 is fissible). Weapon-grade uranium is +90% U235.14a What is depleted uranium? We start out with natural uranium and extract enriched uranium for nuclear fuel and weaponry. The leftover from the extraction process is something very similar to natural uranium, known as “depleted uranium”. The only difference is that DU has 0.202% of U235 and 0.0008% of U234.14a How much DU do we currently have? As of June 1998, we have around 57,800 huge steel cylinders of DU or 496,000 metric tons. 14b Storage of DU is very complicated and problematic since corrosion of DU storage cylinders often occurs over relatively short periods of time.15
From its time of discovery in 1941 Plutonium has been both beneficial and detrimental to the human race. The isotope most detrimental is Plutonium-239 which has been used to create nuclear weapons. Plutonium-239 was used in the atomic bomb codenamed “Fat Man” that was dropped on Nagasaki during World War II. Normally a nuclear bomb uses 10 kilograms of Plutonium, but “Fat Man” used even less and still caused a lot of destruction. To put it in perspective again just 1 kilogram of Plutonium-239 causes an explosion equal to that of 20,000 tons of TNT. The way Plutonium-239 works in an atomic bomb is it is controlled by explosives until it goes critical and cause a fission chain reaction. When this happens all the energy is released causing a nuclear
Plutonium, which is a byproduct of the fission process, can also be used for manufacturing weapons and only requires 2-10kg to develop weapons. The atom bomb that landed in Nagasaki contained plutonium fuel. Depleted uranium, which is the left over from the enrichment process, is used to make military grade armor piercing bullets. These DU penetrators have been used in wars throughout history, the most recent being the Gulf wars. This is a disadvantage because the depleted uranium is toxic and has been scientifically proven to cause birth defects, cancer, and death where it was used.
mining of uranium which is a resource used to creating nuclear weapons also causes nuclear
Cost and availability of fuel is a considerable factor when dealing with nuclear power. Fission requires an element that can be easily split in a particle accelerator, such as uranium or plutonium. Fusion, on the other hand, uses isotopes of hydrogen atoms, specifically deuterium and tritium, that can be obtained from ordinary water. Uranium ores occur naturally in many parts of the world but must go through a costly purification process before used as fuel. The unprocessed ore contains approximately 99.3% uranium-238, a non-fissionable isotope of uranium, and only about 0.7% of U-235 required for fission. One hydrogen atom out of 6700 appears as deuterium, a naturally occurring isotope of hydrogen with an extra neutron, and can easily be separated from the rest. Uranium-235 is a non-renewable resource that will eventually run out, much like the fossil fuels. The abundance of deuterium and lithium provide a virtually unlimited supply of fuel for nuclear fusion. Therefore, nuclear fusion seems to be the better choice.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
Between U-235 and U-238, which one contains more natural uranium, and how can the 2 be separated to obtain pure U-235?

As the demand for global energy rises, nuclear energy is the world 's largest source of emission-free energy and has more energy than any other fuels on earth in a weight to energy produced ratio. Nuclear power plants are capable of providing larger amount of energy in a minimum amount of space. As the scientists at The Nuclear Fuel Cycle wrote : “Typically, some 44 million kilowatts per hour of electricity are produced from one ton of natural Uranium. The production of this amount of electrical power from fossil fuels would require the burning over 20,000 tons of black coal or 8.5 million cubic meters of gas.” Nuclear energy has very high volume to energy production ratio; this is due to the elements which are used as nuclear fuels such as uranium, plutonium, and other nuclear elements which are used as nuclear fuels. Nuclear fuels release their potential chemical energy
Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (primarily a mix of uranium oxides) in 1789.Klaproth, as well as the rest of the scientific community, believed that the substance he extracted from pitchblende was pure uranium, it was actually uranium dioxide (UO2). After noticing that 'pure' uranium reacted oddly with uranium tetrachloride (UCl4), Radioactivity was first discovered in 1896 when Antoine Henri Becquerel, a French physicist, detected it from a sample of uranium. Today, uranium is obtained from uranium ores such as pitchblende, uraninite , carnotite and autunite as well as from phosphate rock , lignite (brown coal) and monazite sand . Since there is little demand for uranium metal, uranium is usually sold in the form of sodium diuranate , also known as yellow cake, or triuranium octoxide).
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
