Cherenkov radiation is the electromagnetic radiation emitted by particles moving through a medium faster than the speed of light in the same medium. It was fist a detected by Soviet scientist Pavel Alekseyevich Cherenkov, of who the effect is named after and a theory was later developed by Ilya Frank and Igor Tamm. Cherenkov’s contributionsRead MoreStatement of Purpose to Study at University of Illinois for Graduate Studies808 Words   |  3 Pages However, on the other hand, many other students do what they want by measuring the pros of the situation and head directly to achieve their goals despite some of the obstacles they face. Convincing my parents that studying abroad for nucle ar engineering and power generation in the UIUC will improve my education, develop my social skills and guarantee me a better career. Firstly, the education standard and technology applied in the University of Illinois is better than that of AUS. University ofRead MoreThe Physics Concepts And Principles Behind Nuclear Fusion1458 Words   |  6 Pagesreport outlines the physics concepts and principles behind nuclear Fusion, the advantages and disadvantages of fusion and whether nuclear fusion could be used in New Zealand. Also, this report outlines the comparison between Fusion and Fission. A fusion is when a reaction in light nuclei combines to form a nucleus with greater mass. Fusion can take place only under extremely high temperature conditions. Another name for this process is thermonuclear reaction. The process of nuclear fusion is importantRead MoreThe Duty of Nuclear Engineers Essay1311 Words   |  6 PagesDescription Nuclear engineers play a huge role in the research and development of methods to make use of nuclear energy for medical, military defence and energy fuel. Another main duty of nuclear engineers is in the handling and disposal of nuclear waste, which means there may be exposure to nuclear chemicals. As well as, an engineer in the nuclear industry, you would be responsible for the safe and productive running of nuclear power stations. In addition the skills you need to become a nuclear engineerRead MoreEssay on Nuclear Energy Is a Cheaper Alternative to Petroleum1531 Words   |  7 Pagespetroleum is cheaper, nuclear energy presents itself as a much stronger alternative to petroleum. This is because the cost of petroleum mining within the next fifty years or so will be too large to be an efficient energy source. A switch to nuclear energy may be more efficient as well as less hazardous to the environment as nuclear power plants emit much less carbon dioxide than fuel plants do. The Wo rld Nuclear Association went on to say â€Å"Greenhouse gas emissions of nuclear power plants are among theRead MoreNuclear Energy Is The Most Suitable Option For Australia1150 Words   |  5 PagesNuclear energy has a potential for replacing fossil fuel in Australia which will be limited in the future. According to Graaff (2015), in 2013, 6350 tonnes of uranium were mined from three uranium mines in Australia, making Australia as a third rank after Canada and Kazakhstan. Therefore, Australia should use Uranium to generate nuclear energy as an alternative energy of fossil fuel. It is important to consider the benefits of nuclear energy in order to prevent global warming implications, suchRead MoreIs Nuclear Power Worth the Risk? Essay1099 Words   |  5 Pagesof Using Nuclear Energy In the following, the benefits and drawbacks of generating electricity with the use of nuclear energy will be discussed. Advantages Large amount of energy production Nuclear power produces huge amount of energy through nuclear fission. 1 ton of uranium fuel, which is used as a fuel in generating electricity, equals to 50,000 tons of fossil fuels for generating the same amount of electricity. Since a small amount of nuclear fuel can produce a large amount of energy, it is powerfulRead More Unlocking the Secrets of the Universe Essay example1762 Words   |  8 Pagesknowledge of Physics, using the scientific method to make observations and test hypotheses is essential to unlocking the secrets of the universe. Energy is one of the most fundamental elements of the universe. Throughout history, man has endeavored to expose, understand, and explain how and why things work.
