Fission reactions are the process in which a nucleus splits, forming two smaller nuclei and fusion reactions are the process in which two nuclei fuse together forming a larger nuclei. Nuclear reactors use controlled nuclear reactions to produce electricity. Nuclear energy is a more efficient energy source than any other available energy sources. The Three Mile Island nuclear disaster brought about sweeping changes in many areas of nuclear safety. Nuclear reactors have been designed to automatically shut down in the case of an earthquake.
Nuclear Energy Nuclear energy-This is energy that binds together components of an atomic nucleus. This is made by the process of nuclear fission. Nuclear fission is produced when an atomic atom is split. The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate of the splitting of the nuclei at once which causes watts of electricity to be forced into the energy type.
Nuclear Power Producing energy from a nuclear power plant is very complicated. The process of nuclear energy involves the fission of atoms, the release of energy from fission as heat, and the transfer of heat to electricity in power plants. The process of splitting the atom is called nuclear fission. Fission can take place in many different kinds of atoms. This explanation uses Uranium - 235, the atom most commonly used in nuclear reactors.
The most important isotope is plutonium 239, or Pu-239. When struck by a neutron, this isotope undergoes a process called fission. In fission, When struck by a neutron, the nucleus of the plutonium atom is split into two nearly equal parts, and energy is released. Although the energy released by one atom is not much, the splitting of the nucleus releases more neutrons, which strike more plutonium atoms. This process, called a chain- reaction, produces enormous amounts of energy.
This new group of nuclear explosives involved getting energy sources from within the nucleus of the atom. The Atomic bomb gained its power from the fission of all of the atomic nuclei in several kilos of uranium. A Ball about the size of a baseball made an explosion equal to about 20,000 tons of TNT. An atomic bomb can also be called a fission bomb because it uses fission to release the nuclear power from the fuel. The fuel is usually either Uranium-235 or plutomium-239.
December 1953, President Dwight D. Eisenhower decided to make nuclear information available to other countries (snedden 13). A combined 371,762 megawatts were produced in 2012 (Nuclear History Timeline 1). Nuclear energy has it's benefits but is also dangerous. Nuclear energy is dangerous because of nuclear radiation, nuclear meltdowns, and environmental dangers. German chemist Martin Klaproth discovered uranium in 1789 (“Outline History of Nuclear Energy” 1).
