Nuclear Fusion Term paper
While the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. If you are in a time crunch, then you need a custom written term paper on your subject (nuclear fusion)
Here you can hire an independent writer/researcher to custom write you an authentic essay to your specifications that will pass any plagiarism test (e.g. Turnitin). Waste no more time!
Nuclear Fusion is constantly present in our solar system. In the core of the sun, Hydrogen is converted to Helium providing enough energy to sustain life on earth. This process occurs at temperatures of 10-15 million degrees Celsius.
Scientists are now trying different methods here on Earth to make fusion the next large-scale energy source. The most suitable reaction occurs between the nuclei of the two isotopes of Hydrogen - Deuterium and Tritium. Scientist have already begun to test reactions involving just Deuterium or Deuterium and Helium (3He).
The basic equation for D-T is Deuterium + Tritium = Helium-4 + neutron.
The amount of material fuel needed for fusion is rather low. For example 10 grams of Deuterium and 15g of Tritium would produce enough fuel for the lifetime electricity needs of an average person in an industrialized country.
The problems with fusion have been numerous. One of the problems is attaining the correct temperature for fusion to take place without using more energy then you produce. Fusion reactions occur at a sufficient rate only at very high temperatures. Over 100 million degrees Celsius is needed for the Deuterium-Tritium reaction, while other reactions require even higher temperatures.
The density of fuel ions must be sufficiently large for fusion reactions to take place at the required rate. The fusion power generated is reduced if the fuel is diluted by impurity atoms released from surrounding material surfaces or by the accumulation of Helium "ash" from the fusion reaction. As fuel ions are burnt in the fusion process they must be replaced by new fuel and the Helium ash must be removed. To fuel nuclear fusion reactions, scientists heat a gas until its components separate in a process appropriately named dissociation. Once the gas's particles are separated into a mass of charged particles, ions, and electrons, plasma is formed. Plasma, characterized by very hot temperatures, is the actual fuel of fusion reactions as well as the fourth state of matter. Because plasma is commonly found floating in space or in stars, it is the most common state of matter. On earth, you can see plasma in flames, aurora, fluorescent lighting, neon signs, and lightning.
Even with the hot plasma formed from heating gas until dissociation, fusion reactions aren't likely to occur because of the repulsion between similar or like charges. To overcome...
