Nuclear energy is an alternative to using fossil fuels. Although nuclear energy is also nonrenewable, it has a much lower amount of air pollution, as well as a lower risk of affecting the climate through global warming. There are three main kinds of nuclear energy, nuclear fusion, nuclear fission, and radioactive decay. This report will explain how nuclear fusion works, as well as explaining the advantages and disadvantages of nuclear fusion.
Nuclear fusion occurs when two or more elements are fused together. Nuclear fusion cannot be used with elements that are heavier than iron, only lighter elements are used. Lighter elements produce more energy. Energy is produced because the mass of the combined elements is lower than the mass of the two separate elements. When the two nuclei combine, some of their mass is converted to energy.
All nuclei have a positive charge and repel each other, which makes it difficult to combine the nuclei. If the nuclei are brought close enough together, though, the nuclei’s attractive force will be high enough to combine the nuclei. The easiest way to bring the nuclei close enough to combine is by accelerating the nuclei. This can be achieved by heating the nuclei up to thermonuclear temperatures. The minimum temperature for achieving nuclear fusion is approximately 100 million Kelvin. At this temperature, hydrogen is plasma.
A fusion reactor reaches the high temperature and pressure needed for fusion. The power needed to start a reactor is about 70 megawatts, but the power produced is about 500 megawatts. Fusion reactions take from 300 to 500 seconds. The temperatures involved in nuclear fusion are too hot for a material container. There are two main kinds of fusion reactors. T...

...ity to construct complex models of the nuclear reactor. The DEISA (Distributed European Infrastructure for Supercomputing Applications) was granted 26 million Euros for this project.
Nuclear fusion has many advantages. One advantage of nuclear fusion is that nuclear fusion produces more energy than any other type of resource. A fusion reaction is measured in MeV, million of electrical volts. A single deuterium- tritium reaction can contain 14 MeVs.
Another advantage of nuclear fusion is that it does not pollute the air with carbon dioxide like burning fossil fuels. It also does not pollute the air with radioactive chemicals like nuclear fission. A third reason nuclear fusion is better is because nuclear fusion has a very small chance of serious nuclear mishaps. Nuclear fission produces many radioactive particles, nuclear fusion produces very few.

Nuclear Energy Essay

- The discovery of nuclear energy began in the 1980’s with Rontgen’s discovery of the X-Ray soon after scientists unraveled the structure of the atom and made the discovery that all atoms have neutrons and protons. The last major component o the atom was discovered in 1932 the neutron. Another important discovery was made in 1938 Germany; the Germans were the first to carry out the fission of uranium atoms. The energy that fission created opened the possibility of two things, powerful weapons, and energy for civilian use....   [tags: Radiation, Radioisotopes, Energy]

IEE Article Review: The Nuclear Fusion of a Hydrogen Atom Essay

- ... Characteristics of such a process would be clean, safe, efficient, and cost effective. The “should be” value of this process is clean energy from a resource that is not usable for any other purpose. A “should be” system would look like is obtain nuclear rod, put it into system, convert nuclear materials to energy, no waste left over. Now for the “as is” section of this process starting with understanding our purpose established in the “should be” section. The reason for the purpose is that we are slowing destroying the earth with the massive amounts of CO2 emissions and if we don’t find an alternative source for energy we will have to either give up harnessing energy all together or keep...   [tags: nuclear plant, laser, alternative fuels]

Nuclear Energy Essay

- Nuclear energy now is the world’s mainly useful form of energy. Energy are devolved and have been used from the fossils fuels and are still be used now, but it is not an option to use it in the future. So this turned that we have a nuclear power as the best choice. There are many positives to nuclear energy over fossil fuels such as less global warming effects. At this time nuclear power provides 6% of the world’s energy and about 14% of the world’s electricity. The best part of this nuclear power is generated from the U.S., Japan, and France....   [tags: Energy ]

Nuclear Energy Essay

- Nuclear Energy Energy consumption has become a necessity and an important part of our daily life in the past 10 years. It seems that the world is looking for an energy source that is cleaner, cheaper and more efficient and since nuclear energy has emerged it has become the forerunner for alternative energy sources. ‘As of 2004, nuclear power provided 6.5% of the world's energy and 15.7% of the world's electricity, with the U.S., France, and Japan together accounting for 57% of nuclear generated electricity’ (‘Nuclear energy facts’ 2007)....   [tags: Renewable Energy]

Essay about Nuclear Energy

- Radiation is a form of energy that we can find almost all around us, there are many other types of radiation that exist, some having more energy than others. Although using these materials could present danger if a great deal of exposure is released. Interaction with any exposed radiation can cause a contamination to surrounding or personal property. We use nuclear energy in what we call nuclear reactors, inside of a nuclear reactor the energy is released as heat and then used as electricity, the process that makes this electricity is fission and fusion, during fission an atomic nuclease will split into separate fragments, which will release in a form of heat and radiation....   [tags: Radiation, Nuclear Weapons]

Creating Energy from Deuterium - Tritium Fusion Essay

- Deuterium-Tritium Fusion Abstract The energy crisis is upon us. Fossil fuels are expected to be totally depleted within the next ten to fifty years. We need an energy source that can consistently output lots of energy and be easily operated. Deuterium-Tritium fusion appears to be the best and most effective way to produce energy. By fusing the two isotopes of Hydrogen in to the heavier element Helium large quantities of energy are released. D-T fusion is the safest form of fusion, producing no waste and no harmful radioactive atoms....   [tags: Alternative Energy Power]

Different Sources for Alternative Energy Essay

- In order to understand alternative energy sources we must first know what they are. Alternative energy sources can be described as energy that actually won’t pollute as much fossil fuel, in addition to being less harmful to the environment as well as humans, lower in cost, lastly, comes from sources of which we won’t run out of. Alternative energy is not to be confused with renewable energy.
