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.

Extractions: EFDA-JET Home Nuclear Fusion Basics Contents : The Nuclear Fusion Reaction Plasma Confinement Conditions for a Fusion Reaction Heating of Plasma Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy to sustain life on earth. For energy production on earth, different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two heavy forms (isotopes) of Hydrogen - Deuterium (D) and Tritium (T); eventually reactions involving just Deuterium or Deuterium and Helium ( He) may be used. Most suitable fusion reaction. At the temperatures required for the D-T fusion reaction - over 100 Million deg. C - the fuel has changed its state from gas to PLASMA. In a plasma, the electrons have been separated from the atomic nuclei (usually called the "ions"). Understanding plasma required major developments in physics. Plasmas are now used widely in industry, especially for semi-conductor manufacture. A vast, new source of energy.

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.

http://www.energyquest.ca.gov/ask_quester/answers_nuclear.html

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.

http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/fusion.html

Extractions: Nuclear Fusion If light nuclei are forced together, they will fuse with a yield of energy because the mass of the combination will be less than the sum of the masses of the individual nuclei. If the combined nuclear mass is less than that of iron at the peak of the binding energy curve, then the nuclear particles will be more tightly bound than they were in the lighter nuclei, and that decrease in mass comes off in the form of energy according to the Einstein relationship . For elements heavier than iron, fission will yield energy. For potential nuclear energy sources for the Earth, the deuterium-tritium fusion reaction contained by some kind of magnetic confinement seems the most likely path. However, for the fueling of the stars , other fusion reactions will dominate. Fusion concepts ... Nuclear R Nave Go Back Deuterium-Tritium Fusion The most promising of the hydrogen fusion reactions which make up the deuterium cycle is the fusion of deuterium and tritium. The reaction yields 17.6 MeV of energy but requires a temperature of approximately 40 million Kelvins to overcome the coulomb barrier and ignite it. The

Extractions: Nuclear Binding Energy Nuclei are made up of protons and neutron , but the mass of a nucleus is always less than the sum of the individual masses of the protons and neutrons which constitute it. The difference is a measure of the nuclear binding energy which holds the nucleus together. This binding energy can be calculated from the Einstein relationship The enormity of the nuclear binding energy can perhaps be better appreciated by comparing it to the binding energy of an electron in an atom. The comparison of the alpha particle binding energy with the binding energy of the electron in a hydrogen atom is shown below. The nuclear binding energies are on the order of a million times greater than the electron binding energies of atoms. Binding energy curve. Nuclear units. Index Nuclear Structure Concepts ... Nuclear R Nave Go Back Fission and fusion can yield energy Nuclear binding energy Fusion example Fission example Further discussion ... Nuclear R Nave Go Back Nuclear Binding Energy Curve The binding energy curve is obtained by dividing the total nuclear binding energy by the number of nucleons. The fact that there is a peak in the binding energy curve in the region of stability near iron means that either the breakup of heavier nuclei (fission) or the combining of lighter nuclei (fusion) will yield nuclei which are more tightly bound (less mass per nucleon).
