Nuclear Energy The sun and stars are seemingly inexhaustible sources of energy. That energy is the result of nuclear reactions, in which matter is converted to energy. We have been able to harness that mechanism and regularly use it to generate power. Presently, nuclear energy provides for approximately 16% of the world's electricity. Unlike the stars, the nuclear reactors that we have today work on the principle of nuclear fission. Scientists are working like madmen to make fusion reactors which have the potential of providing more energy with fewer disadvantages than fission reactors. Production Changes can occur in the structure of the nuclei of atoms. These changes are called nuclear reactions . Energy created in a nuclear reaction is called nuclear energy , or atomic energy Nuclear energy is produced naturally and in man-made operations under human control. Naturally: Some nuclear energy is produced naturally. For example, the Sun and other stars make heat and light by nuclear reactions. Man-Made: Nuclear energy can be man-made too. Machines called

Salvetti R.A. Ricci E. Sindoni Included in series Enrico Fermi International School of Physics, 116 Description This book reinvestigates and analyses, in various aspects and details, the scientific basis of an up-to-date 'nuclear culture' and presents the basic and outstanding problems of this field, with its important technical and social applications and consequences. The contributions are presented by leading experts in this area and the fundamental approaches related to nuclear fission and fusion have been considered and covered. In the light of public opinion regarding nuclear energy as a whole, after the Chernobyl accident, the various items, including safety and ecological problems, are treated beyond the political and social misunderstandings due to ideological and fashionable interferences. The resulting collection of papers therefore satisfy the double need of maintaining a high scientific standard and of presenting the data and the facts in such a way that they can be understood, in their essential aspects, by a more general audience.

Chapter 13: Nuclear Energy - Fission and Fusion 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. Scientists used Einstein's famous equation as the key to unlock atomic energy and also create atomic bombs. The ancient Greeks said the smallest part of nature is an atom. But they did not know 2,000 years ago about nature's even smaller parts.

17. Nuclear Energy 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 http://www.lbl.gov/abc/wallchart/chapters/01/7.html

Chapter Head Home Table of Contents Glossary ... Appendix Nuclear Energy 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.

ABC's of Nuclear Science Nuclear Structure Radioactivity Alpha Decay Beta Decay ... Antimatter Nuclear Structure An atom consists of an extremely small, positively charged nucleus surrounded by a cloud of negatively charged electrons . Although typically the nucleus is less than one ten-thousandth the size of the atom, the nucleus contains more than 99.9% of the mass of the atom! Nuclei consist of positively charged protons and electrically neutral neutrons held together by the so-called strong or nuclear force. This force is much stronger than the familiar electrostatic force that binds the electrons to the nucleus, but its range is limited to distances on the order of a few x10 meters. The number of protons in the nucleus, Z, is called the atomic number . This determines what chemical element the atom is. The number of neutrons in the nucleus is denoted by N . The atomic mass of the nucleus, A, is equal to Z + N . A given element can have many different isotopes, which differ from one another by the number of neutrons contained in the nuclei. In a neutral atom, the number of electrons orbiting the nucleus equals the number of protons in the nucleus. Since the electric charges of the proton and the electron are +1 and-1 respectively (in units of the proton charge), the net charge of the atom is zero. At present, there are 112 known elements which range from the lightest, hydrogen, to the recently discovered and yet to-be-named element 112. All of the elements heavier than uranium are man made. Among the elements are approximately 270 stable isotopes, and more than 2000 unstable isotopes.

20. Nuclear Binding Energy The difference is a measure of the nuclear binding energy which holds the nuclear binding energy, Fusion example, fission example, Further discussion http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/nucbin.html

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).
