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.

FREQUENTLY ASKED QUESTIONS ABOUT NUCLEAR ENERGY by John McCarthy This page discusses nuclear energy as a part of a more general discussion of why human material progress is sustainable and should be sustained. Energy is just one of the questions considered. Up to: Main page on why progress is sustainable Incidentally, I'm Professor of Computer Science at Stanford University, emeritus (means retired) as of 2001 January 1. Here's my main page . I write about sustainability as a volunteer public service. I am not professionally involved with nuclear energy. Here's a new page on Nuclear Energy Now . It is motivated by the Bush Administration in the U.S. having tentatively re-opened the question of building new nuclear plants in the U.S. I hope they persist and are successful. One of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil and natural gas. These are discussed in the main page on energy . They will last quite a while but will probably run out or become harmful in tens to hundreds of years. Solar energy will also work but is not much developed yet except for special applications because of its high cost. This high cost as a main source, e.g. for central station electricity, is likely to continue, and nuclear energy is likely to remain cheaper. Q. What are the details on nuclear energy?

Nuclear Energy (An Overview) Also See Our Nuclear Issues Web Page Nuclear energy in California produced 40,417 million kilowatt/hours (GWh) of electricity in 1999, or 14.66 percent of electricity from all sources. The total dependable capacity of California's nuclear-supplied power is more than 5,300 megawatts, including the two operating nuclear power facilities in California and portions of nuclear facilities in other states owned by California electricity companies. There are two fundamental ways to release energy from nuclear reactions: fission and fusion of atomic nuclei. Electricity generating technologies based on fission are commercially available, whereas fusion is still in the early stages of research and development and is at present only a theoretical possibility for controlled power generation. Nuclear fission is the process of splitting the nuclei of atoms, which releases energy from within those atoms. Nuclear fusion is the process of joining, rather than splitting, such atomic particles with similar releases of energy. FISSION Of the several types of fission reactors, the most common type in the United States is light water reactors (so called because normal (light) water is used to cool the reactor core; some reactors use heavy water, which contains hydrogen atoms with an additional neutron in the nucleus), based on pressurized water reactor (PWR) and boiling water reactor (BWR) technology. PWRs and BWRs use uranium-235, a naturally-occurring radioactive isotope of uranium, as the fuel. As the nucleus of a uranium-235 atom is hit by a neutron, it splits into two smaller atoms of other elements, and releases energy and extra neutrons. Those neutrons hit more atoms of the original uranium-235, creating a fission chain reaction that releases more energy and neutrons.

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.

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). The binding energies of nucleons are in the range of millions of electron volts compared to tens of eV for atomic electrons. Whereas an atomic transition might emit a photon in the range of a few electron volts, perhaps in the visible light region, nuclear transitions can emit

Nuclear Fission If a massive nucleus like uranium-235 breaks apart (fissions), then there will be a net yield of energy because the sum of the masses of the fragments will be less than the mass of the uranium nucleus. If the mass of the fragments is equal to or greater 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 uranium nucleus, and that decrease in mass comes off in the form of energy according to the Einstein equation . For elements lighter than iron, fusion will yield energy. The fission of U-235 in reactors is triggered by the absorption of a low energy neutron, often termed a "slow neutron" or a "thermal neutron". Other fissionable isotopes which can be induced to fission by slow neutrons are plutonium-239, uranium-233, and thorium-232. Uranium-235 Fission Index Fission concepts HyperPhysics ...

NUCLEAR FISSION The first large scale use of nuclear fission occurred on July 16, 1945, in New Mexico, with the test of the world's first atomic bomb. Following the Second World War, research was undertaken on how to use the power of the atom for "peaceful" purposes. In 1955, the U.S. navy submarine "Nautilus" travelled over 62,000 miles, powered by a single lump of uranium the size of a golf ball. Shortly thereafter, electricity was produced in commercial amounts by reactors in both the U.S. and the then Soviet Union; and Canada soon developed its own reactor design, the CANDU reactor. In the following years, nuclear reactors were envisioned as a clean and cheap source of electricity, capable of meeting vastly increased demand in the future. Miniature backyard reactors were also seen as possibilities for supplying heat to single family homes. At the present time, about 430 nuclear reactors are connected to the world's electricity grids, supplying 16% of the world's electricity demand. The majority of these reactors are located in the industrialized countries of the world. This amount of electricity generation is far less than that which had been predicted back in the 1960s when nuclear power was in its infancy. The increasing cost of nuclear power plant construction is one reason why nuclear energy has not lived up to its potential; but the main reason is safety concerns. Nuclear power plant accidents such as those at Three Mile Island in Pennsylvania and Chernobyl in the former U.S.S.R. have drastically increased public opposition to nuclear power. Recent worldwide concern over the threats of global warming and acid rain has, however, resulted in some renewed interest.

It is an important factor in reducing Europe's energy dependence. However, over the past two decades it has been the centre of much controversy - so much so that several European countries have decided to dispense with it. No doubt the reservations have more to do with the issue of waste management than the safety of installations.

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 that 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.

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.

Site Map (S-8) Nuclear Power Note: This is a side-excursion into the basics of nuclear energy Bear in mind that even without math, this can be a fairly difficult subject and that the discussion is rather lengthy. The ideas from section S-7 are reviewed in what follows next. The rest of the section is a qualitative discussion of all key processes involved in the practical use nuclear energy. A Review of Nuclear Structure The way the Sun generates its energy helps understand the way a nuclear power station does so. The two processes are however quite different. Here some facts about the way protons and neutrons combine to form nuclei, as covered in section S-7 about the Sun: helium Unlike gravity or electrical forces, the nuclear force is effective only at very short distances. At greater distances, the protons repel each other because they are positively charged, and charges of the same kind repel. For that reason, the protons forming the nuclei of ordinary hydrogenfor instance, in a balloon filled with hydrogendo not combine to form helium (a process which also would require some to combine with electrons and become neutrons). They cannot get close enough for the nuclear force, which attracts them to each other, to become important! Only in the core of the Sun, under extreme pressure and temperature, can such a process take place. Other small nuclei can similarly combine into bigger ones and release energy, but in combining such nuclei, the amount of energy released is much smaller. The reason is that while the process

College of Engineering University of Wisconsin - Madison University of Wisconsin Nuclear Reactor Tour Nuclear Energy 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.
