Nuclear power is a very broad field that is compromised by many aspects of science including physics and chemistry. It was discovered in the early 1900s. It is a power source widely used by the United States due to the shear amount of energy that can be created from just two atoms. Nuclear fission, the most widely used form of nuclear power, creates incredible amounts energy incredibly efficiently and due to this it is actually really popular. Nuclear power is hailed to be eco-friendly but it is argued that the radioactive wastes and the constant potential for something to go wrong is too great a risk to the environment and people.
1. A Not So Brief History
In 1789 German chemist Martin Klaproth discovered uranium, naming after Uranus. It was not until the late 1800s that radiation was discovered. It was around this time that scientists found that certain elements gave off alpha, beta, and gamma radiation (“Outline History of Nuclear Energy”). Pierre and Marie Curie coined the term radioactivity in 1896 to name the phenomenon of an element emitting alpha, beta, and/or gamma waves. In 1911 naturally radioactive elements were found to have many isotopes with the same chemistry. James Chadwick discovered the neutron in 1932, the same year that Cockcroft and Walton discovered that bombarding atoms with accelerated protons caused nuclear transformations in the atoms. Two years later Irene Curie and Frederic Joliot found that these nuclear transformations created artificial isotopes. Enrico Fermi experimented with bombarding the atoms with neutrons and, in 1935, discovered that this created even more artificial isotopes which lead to the creation of heavier and lighter elements. Otto Hans and Fritz Strassman discovered in 1938 that some...

... into more. It is amazingly efficient in its production of energy. The incidents involving meltdowns have been few and far in between with a total of three occurring since the introduction of nuclear fission as a viable form for the production of electricity. All the byproducts from the production of the electricity are environmentally friendly with the exception of the depleted uranium. Using it would actually save the government and the average citizen an incredible amount of money. The dangers are few and far in between with many fail safes and precautions being implemented at the nuclear power plants. Nuclear power has the potential to completely replace the use of fossil fuel for the generation of electricity in the future. Overall nuclear power is a very useful and viable form of electricity production that should really be researched and invested into more.
Nuclear power is a growing source of energy to most of the world for many benefits. People doubt the significant of nuclear power because of one accident. Due to this accident, the world has only seen the flaws in nuclear power and not the many benefits it has to offer. Nuclear power would benefit worldwide if people would let go of the past and look towards the future. Nuclear power is a better alternative energy because of its economic and environmental benefits.
Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”.
In my opinion nuclear power is pretty amazing, and I doubt that people really believe otherwise. The amount of energy that it can produce compared to other sources of energy is huge. I believe that as long as it is done with the utmost care, nuclear power is the best source of energy we can
Albert Einstein predicted that mass could be converted into energy early in the century and was confirmed experimentally by John D. Cockcroft and Ernest Walton in 1932. In 1939, Otto Hahn and Fritz Strassmann discovered that neutrons striking the element uranium caused the atoms to split apart. Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, caused them to split, and start a chain reaction. If the chain reaction were limited to a moderate pace, a new source of energy could be the result. The chain reaction could release energy rapidly and with explosive force.
Nuclear energy is a very powerful source of energy. Just a little bit is required to make large amounts of electricity, which powers 1 in 5 households in the U.S. Nuclear energy has been advanced over the years and has been relied on heavily by many countries today.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.
Nuclear energy will always be a source for electricity. It has its pros and its cons but nuclear energy is reliable and it will always be available for developing nations. It takes time for countries to build power plants because it isn’t cheap. Also because of high radiation levels, people will always need to be careful when working around uranium because it can cause cancer. Power plants and nuclear energy will always be in use all over the world.
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
“The half-life of a radioisotope is the time required for half the atoms in a given sample to undergo radioactive decay; for any particular radioisotope, the half-life is independent of the initial amount of...
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
Uranium, a radioactive element, was first mined in the western United States in 1871 by Dr. Richard Pierce, who shipped 200 pounds of pitchblende to London from the Central City Mining District. This element is sorta boring but I found something interesting, they used it to make an an atomic bomb in the Cold War. In 1898 Pierre and Marie Curie and G. Bemont isolated the "miracle element" radium from pitchblende. That same year, uranium, vanadium and radium were found to exist in carnotite, a mineral containing colorful red and yellow ores that had been used as body paint by early Navajo and Ute Indians on the Colorado Plateau. The discovery triggered a small prospecting boom in southeastern Utah, and radium mines in Grand and San Juan counties became a major source of ore for the Curies. It was not the Curies but a British team working in Canada which was the first to understand that the presence of polonium and radium in pitchblende was not due to simple geological and mineral reasons, but that these elements were directly linked to uranium by a process of natural radioactive transmutation. The theory of radioactive transformation of elements was brilliantly enlarge in1901 by the New Zealand physicist Ernest Rutherford and the English chemist Frederick Soddy at McGill University in Montreal. At dusk on the evening of November 8, 1895, Wilhelm Rontgen, professor of physics at the University of Wurzburg in Germany, noticed a cathode tube that a sheet of paper come distance away. He put his hand between the tube and the paper, he saw the image of the bones in his hand on the paper.
Wilhelm Roentgen discovered radiation which is also known as x-ray in 1895. Radiation is energy turned into waves or particles in
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
