Extractions: Another major form of energy is nuclear energy, the energy that is trapped inside each atom. One of the laws of the universe is that matter and energy can't be created nor destroyed. But they can be changed in form. Matter can be changed into energy. The world's most famous scientist, Albert Einstein , created the mathematical formula that explains this. It is: E m c This equation says: E [energy] equals m [mass] times c c stands for the velocity or the speed of light. c means c times c, or the speed of light raised to the second power or c-squared.] You can listen to Einstein's voice explaining this at: www.aip.org/history/einstein/voice1.htm Please note that some web browser software may not show an exponent (raising something to a power, a mathematical expression) on the Internet. Normally c-squared is shown with a smaller "2" placed above and to the right of the c.

Extractions: I was wondering... when you split two positively charged atoms, you make nuclear energy. But, when they try to make cold fusion, they split two negatively charged atoms and can't do it. Why can't you try to split a positive and a negative atom to make cold fusion? (I know you have to have nickel to do it also!) -Thanks (John, 8th grade, Queen of Angels School, B.C. Canada) The Professor Answers: Dear John: It's not really a question of two positively charged atoms versus two negatively charges ones when discussing nuclear power. First, you already know that atoms are made up of protons (positive charge), electrons (negative charge) and neutrons (neutral charge). Because atoms have the same number of electrons and protons, the positive and negative charges balance equally. The force that holds the protons and neutrons together in the nucleus is called nuclear force. Each atom of Uranium-235, the fissionable isotope of uranium, contains 92 protons, 92 electrons and 143 neutrons. That's what makes it an isotope; having more neutrons. Although each atom is balanced, all nuclei are unstable to a certain degree. The bigger the nucleus, the more unstable it is. It is this instability that makes U-235 perfect for fission to occur. The balanced, but large, unstable U-235 nucleus is bombarded by neutrons. When a neutron hits the nucleus, the nucleus splits into two smaller, more stable nuclei. These smaller nuclei need fewer neutrons to make them stable and two or three neutrons are usually released. These then cause other nuclei to break up and can start a chain reaction. The energy needed to hold all of the particles together in the new nuclei is less than that required in the original nucleus and the "spare" energy is released, mostly as heat.

Extractions: Chapter Head Home Table of Contents Glossary ... Appendix Fission Fission occurs when the nucleus of an atom divides into two smaller nuclei. Fission can occur spontaneously; it may also be induced by the capture of a neutron. For example, an excited state of uranium (created by neutron capture) can split into smaller " daughter " nuclei. Fission products will often emit neutrons because the N/Z ratio is greater at higher Z. With a proper arrangement of uranium atoms, it is possible to have the neutrons resulting from the first fission event be captured and to cause more uranium nuclei to fission. This "chain reaction" process causes the number of uranium atoms that fission to increase exponentially. When the uranium nucleus fissions, it releases a considerable amount of energy. This process is carried on in a controlled manner in a nuclear reactor, where control rods capture excess neutrons, preventing them from being captured by other uranium nuclei to induce yet another uranium fission. Nuclear reactors are designed so that the release of energy is slow and can be used for practical generation of energy. In an atomic bomb, the chain reaction is explosively rapid.

Programme objectives The goal of the Nuclear Energy Programme is to help exploit the full potential of nuclear energy, both fusion and fission, in a sustainable manner, by making current technologies even safer and more economical and by exploring promising new concepts. The availability of secure, sustainable and competitive sources of energy is essential to economic growth, prosperity and quality of life in Europe. In view of the expected growth in demand for energy, continued use will need to be made of all potential sources. Nuclear energy has the potential to provide Europe with a secure and sustainable electricity supply at a competitive price. It also makes a significant contribution to the policy of diversifying energy supply and reducing overall emissions of CO2. Efforts to develop the safety and security of nuclear energy systems can strengthen the Community's industrial competitiveness, through exploiting the European technological advance and enhance the acceptability of nuclear energy.

In these processes a small amount of mass is converted to energy according to the relationship E mc , where E is energy, m is mass, and c is the speed of light (see relativity ). The most pressing problems concerning nuclear energy are the possibility of an accident at a nuclear reactor or fuel plant, such as those which occurred at Three Mile Island Chernobyl (1986), and Takaimura, Japan (1999), and the potential threat to the continued existence of the human race posed by nuclear weapons (see disarmament, nuclear Sections in this article:

Extractions: Clean Nuclear Energy via Isotopic Transformation The First Artificial Accelerated Decay Transformation On April 28, 1932, at a meeting of the Royal Society, Lord Rutherford announced that two of the workers in Cavendish Laboratory, J. D. Cockcroft and E. T. S. Walton, had successfully demonstrated the release of excess radioactive energy from lithium elements and other light elements by protons entirely artificially generated by high electric potentials. The most surprising feature at the time was the relatively low voltage necessary. The generator installed had a peak voltage of about 750,000 volts, but artificial decay started at only one-sixth of this, 125,000 volts. Indeed, later Rutherford, using deuterons (atoms of the hydrogen isotope of mass 2) instead of protons, pushed back the starting point to some 20,000 to 40,000 volts, which is well within the range of quite a small x-ray induction coil. The protons were generated in a long vertical hydrogen vacuum-tube, specially designed to withstand the high voltage, and with a window of the thinnest possible mica leaf at the end, through which they emerged to impinge on the target element being bombarded. The protons were estimated to have a velocity of one-thirtieth of that of light, and their range in air was only 1 cm. The bombarded substance was examined by the scintillations produced in

http://reactor.engr.wisc.edu/fission.htm

Extractions: University of Wisconsin - Madison Atoms are the building blocks from which matter is formed. Everything around us is made up of atoms. Nuclear energy is contained within the center of the atom in a place known as the nucleus . Particles within the nucleus are held together by a strong force. If a large nucleus is split apart (fission) , generous amounts of energy can be liberated. Small nuclei can also be combined (fusion) with an accompanying release of energy. Using this strong force that holds the nucleus together to produce energy is essentially what the field of nuclear power generation is about. In the fission process certain heavy elements, such as some forms of Uranium , are split when a neutron strikes them. When they split, they release energy in the form of kinetic energy (heat) and radiation . The process not only produces energy but also additional neutrons that can be used to fission other Uranium nuclei and start a chain reaction.

Extractions: University of California, Berkeley Scientists have conceived of a number of approaches to harness fusionthe source of energy that heats the starsas a future nonpolluting energy source. These web pages explore one potential route, called inertial confinement fusion , providing a largely nontechnical introduction to the technology. F usion's promise as an energy source comes from its inexhaustible fuel supply, and from its potential for almost negligible environmental impact compared to the environmental costs of competing energy sources: the air pollution and carbon dioxide emission from fossil fuel combustion; high-level radioactive waste generation from nuclear fission; and the emissions from the production of the larger quantities of concrete, steel, glass and other materials required to collect dilute solar energy. Significant technical barriers must be overcome before fusion could compete economically with these other energy sources. These notes focus on a specific technologyinertial confinement fusion (ICF)and outline reasons to be optimistic that the inertial route to fusion energy also promises economical viability. Thus, besides discussing the basics of fusion reactions, how ICF "targets" work, and what major components would go into an inertial fusion energy (IFE) power plant, these notes also present the latest economic estimates for IFE power.

http://www.geocities.com/eddly_17/nuclear_energy_.htm

Extractions: An atom's nucleus can be split apart. When this is done, a tremendous amount of energy is released. The energy is both heat and light energy. This energy, when let out slowly, can be harnessed to generate electricity. When it is let out all at once, it makes a tremendous explosion in an atomic bomb. The word fission means to split apart. A nuclear power plant (like Diablo Canyon Nuclear Plant shown on the right) uses uranium as a "fuel." Uranium is an element that is dug out of the ground many places around the world. It is processed into tiny pellets that are loaded into very long rods that are put into the power plant's reactor. Inside the reactor of an atomic power plant, uranium atoms are split apart in a controlled chain reaction. In a chain reaction, particles released by the splitting of the atom go off and strike other uranium atoms splitting those. Those particles given off split still other atoms in a chain reaction. In nuclear power plants, control rods are used to keep the splitting regulated so it doesn't go too fast. If the reaction is not controlled, you could have an atomic bomb. But in atomic bombs, almost pure pieces of the element Uranium-235 or Plutonium, of a precise mass and shape, must be brought together and held together, with great force. These conditions are not present in a nuclear reactor.
