Nuclear Energy: How Is Nuclear Energy Created?
Nuclear Energy
Nuclear energy results from mass-to-energy conversions that occur in the separation of atoms larger than Iron or combining atoms smaller than Iron. The slight amount of mass that is lost from either the separation or combination follows the Einstein’s mass energy relation E=mc2 where m is defined as the mass and c is the speed of light.
How is Nuclear Energy Created?
Nuclear energy is created either from the Fusion or Fission of atoms.
Nuclear fusion is the joining of two small atoms such as Hydrogen or Helium to produce heavier atoms. This reaction can release more energy than fission without producing radioactive by-products. Fusion reactions occur in the sun, using Hydrogen as fuel and producing Helium as waste. Nuclear fusion

This is evident in Figure … where an equivalent amount of energy is given, the nuclear energy is able to sustain power up to years, where normal fossil fuel can only sustain up to a few days. Although there are debates that the life span of nuclear power sources such as Uranium is low and is comparable to oil, this do not pose a threat as nuclear energy can be recycled.
In addition, nuclear power plant only emits hot water into the environment which makes it environmental friendly. In fact, little or almost no carbon dioxide is being released into the atmosphere. The little amount of carbon dioxide is produced because of the mining and construction of the power plant, however the amount released is not comparable to that of other fossil fuel.
Finally, with nuclear energy, people now need not depend solely on traditional fossil fuel to generate electricity. Since the nuclear power fuel can reach a temperature in the magnitude of thousands, it can be thermo-chemically broken down into Oxygen and Hydrogen which can be used to power up vehicles Most of the world supply of uranium is in Australia and Canada. With fuel recycling, the supply of Uranium is not a

The Moderator. It is a material found in the core which slows down the fission process so that a rapid continuation of fission process can take place.
3. The control rods. The rods are made with cadmium, hafnium or boron which can absorb the neutrons. These are inserted or withdrawn from the core to control the rate of reaction or to temporarily stop it. This is so as in the process of fission, the release of some neutrons are delayed. In order to enable a smooth chain reacting system, the release has to be controlled in order to hold the precise criticality.
4. The Coolant. It is a liquid that flows through the core in order to transfer the heat. This is exceptionally important in order to maintain the temperature and avoid overheating of the core.
5. Pressure vessel. It is normally a steel vessel which contain the core, moderator and coolant.
6. Steam Generator. It forms a portion of the cooling system of pressurised water reactors. The high pressure primary coolant transfers the heat from the reactor and is used to generate steam in a secondary
Helen Cadicott Nuclear Power Is Not The Answer Summary
939 Words | 4 PagesIn “Nuclear Power is Not the Answer,” Helen Caldicott argues that pursuing nuclear energy would be a detriment to the United States. According to Caldicott, nuclear power, contrary to what the industry claims, is not clean and green, but rather a pollutant and a strong contributor to the destruction of the ozone layer. Because of the availability of uranium ore steadily decreasing, the process is requiring more and more fossil fuels to extract the ore. Caldicott projects that within ten to twenty years, nuclear reactors will be counterproductive because of the amount of fossil fuel it will take to mine the remaining uranium. In addition to air pollution, nuclear power plants also emit radioactive gases and materials that have the potential
Examples Of Proof Why Canada Should Use More Nuclear Energy
695 Words | 3 PagesFacts, data, expert opinion: a) Low Pollution such as air pollution, water pollution - Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn’t discharge any gasses like methane and carbon dioxide b) Low Operating Costs - The cost of the uranium, which is utilized as a fuel in this process, is low. Also, even though the expense of setting up nuclear power plants is moderately high, the expense of running them is quite low. The normal life of nuclear reactor is anywhere from 40-60 years, depending on how often it is used and how it is being
Compare And Contrast Three Mile Island And Chernobyl
348 Words | 2 PagesThe general attitude by the public towards nuclear reactors is that of fear or disapproval simply due to its name or the rumors. Nuclear reactors are merely devices that sustain chain reactions, in which only one of the emitted neutrons hits another nucleus to create fission. Though nuclear reactors cannot become a weapon or a bomb, some of the dangers relate to our lives to the extent that we may need to seek alternatives, as demonstrated by the reactors in Three Mile Island and Chernobyl. Nuclear reactors operate on chain reaction, which does not grow due to neutron multiplications of 1. They depend on slow neutrons—in explosion, they are only as powerful as TNT.
The Pros And Cons Of Nuclear Power Plants
824 Words | 4 PagesOver 20 percent of the energy in the United States comes from nuclear energy power plants. (Rinkesh, 2018) They so their best to get as much energy to the country as possible, but there are those out there who don’t agree with them. While there are downsides to nuclear energy, the pros vastly outweigh the cons. Nuclear power plants are a great way to get energy because they don’t let out much pollution, are very efficient, and are very safe.
Argumentative Essay-Nuclear Energy Is Australia's Future
607 Words | 3 PagesNuclear power produces fewer carbon emissions than traditional energy sources because energy is not produced by burning molecules but splitting atoms. ‘An energy mix including nuclear power has the lowest impact on wildlife and Ecosystems’ as shown by a Conservation Biology paper. Consequently, greenhouse gas emissions have reduced by nearly half which shows the benefits and popularity of nuclear power use. Nuclear power has many environmental benefits such as small waste production, leaves no adverse effect on water, land or any habitats. By reducing fossil fuel consumption and switching to Nuclear Energy, we will sustain the environment, quality of air, improving the overall quality of
Compare And Contrast Nuclear Fission Vs Nuclear Fusion
138 Words | 1 PagesNuclear fission can be similar to nuclear fusion for example they both release heat energy. However, in nuclear fusion: • two nuclei must join together • Extremely high temperatures are needed. To develop further: Nuclear fusion is the joining of smaller nuclei to make larger ones. For example; Deuterium and Tritium form to make a bigger and heavier nucleus and Helium releases a lot of energy. Nuclear fusion also happens in stars..
Advantages And Disadvantages Of Nuclear Energy
1375 Words | 6 PagesNUCLEAR ENERGY Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particles that can break a material. Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom.
Fission Vs Nuclear Fusion Essay
1284 Words | 6 PagesNuclear fission and nuclear fusion are reactions that release energy because of the high-powered atomic bonds between the particles in the nucleus. To understand fission and fusion reactions, we must first understand the difference between them. In a fission reaction, a massive nucleus is split in the form of gamma rays, free neutrons and other subatomic particles. In a fusion reaction, two nuclei combine to form a new element that contains more protons in the nucleus (higher atomic number). Those are the basic definitions of the fusion and fission reactions.

Persuasive Speech: Nuclear Energy Vs. Solar Energy
1466 Words | 6 PagesProbably words like radiation, mutations and Homer Simpson pop into your head. However, that is not the case. According to Mark A. Jones, Director of Nuclear Operations and Engineering at Hutchinson Island Nuclear Power Plant, during our interview stated: “Nuclear energy compared to solar energy brings less of an impact because nuclear energy doesn 't emit air pollution unlike other forms of energy. It also only needs the fraction of land the salon energy needs and self-contain its own waste from polluting the environment.”
Nuclear Power Argumentative Essay
944 Words | 4 PagesNuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).
Nuclear Energy Thesis
1617 Words | 7 Pages01 June 2015. Since some of them might offer a partial position on the topic, pro or against nuclear energy I will try to compare their data every time I am talking about a specific event or situation in order to provide data that are as objective as possible. Even though a thesis should be used to demonstrate a position it is politically correct to list the same data from different sources and not just by the one that is more similar to my position. 8. Main Objectives Nuclear energy has become an integral part our lives.
Nuclear Fusion Is A Major Part Of A Star's Life
868 Words | 4 PagesNuclear fusion creates an outward pressure that balances with the inward pressure caused by gravity which stabilizes the star and for most of its life a star will spend it in its stable phase. Main sequence stars fuse hydrogen atoms to form helium atoms in its cores and approximately 90% of the stars in the universe, including the sun, are main sequence stars.3 The bigger a star is, the more it needs to burn hydrogen fuel to avoid the star from having a gravitational collapse. Bigger stars have higher temperatures because they require more fuel to burn. 4 Stars begin their lives mostly made with 70% hydrogen and 28% helium.
Houtermans Theory Of Nuclear Fusion
1638 Words | 7 PagesFor example, the energy released by a deuterium-tritium collision, both isotopes of hydrogen, is 17.6 MeV. One gram of matter used in this reaction would result in an incredible 339 GJ. In comparison, only 13.6 eV is released by adding an electron to a hydrogen nucleus. While individual atoms in nuclear fission do produce more energy than individual atoms in nuclear fusion, because atoms are much lighter in fusion than in fission, the energy per unit of mass is far greater in nuclear fusion than in fission. This means we cannot disregard the immense potential in nuclear fusion as a clean energy source. NUCLEAR FUSION IN NATURE: STARS
Nuclear Advantages
1005 Words | 5 PagesIn addition to the process of nuclear system, the disposal of nuclear waste, which results during the generation of nuclear power is much easier to deal with. The reason is because it is just dumped in to a geological site where it decays over a period of time and has not negative impact on the environmental. This is also the main advantage of nuclear energy compared to the other chemical used generating system, which cause much more poisonous gases. Most of the generating energy system came up with problem that lack of source to generate enough, however, the source of nuclear power is uranium, which is available in abundance in the crust of the Earth with major deposits being uncovered in Canada and Australia. Since the source of nuclear power is available for more than century to come, this energy system is strongly inexhaustible.
