@import url("/includes/css/bch_main5.css"); /*IE and NN6x styles*/ Home Community Involvement in Education Education - 8-12 - Nuclear Energy Nuclear energy is energy that is obtained by converting matter into energy. Matter is the physical substance things are made of. All matter is made up of atoms, consisting of a central nucleus surrounded by electrons. In some cases, the nucleus is unstable, and spontaneously breaks apart, releasing nuclear fragments and energy. This process is called radioactivity . Over the last 50 years, scientists have found ways to control some nuclear processes so that heat energy can be produced to generate electricity. This type of energy is called nuclear or atomic energy. Two different processes, called fission and fusion, yield nuclear energy. Fission is the process used in nuclear-powered electricity generating plants. It involves breaking apart large nuclei, usually from uranium or plutonium, into smaller parts. The smaller parts have less mass than the original nucleus had. The lost matter is converted into energy. Atomic bombs are created when a few kilograms of uranium are converted into energy all at once, with no controls to slow down or restrain the conversion of uranium nuclei into energy. Fusion takes place when two nuclei of hydrogen join together to form one nucleus of helium. The new helium nucleus has a little less mass than the two hydrogen atoms. The mass has been converted into energy.

Nuclear Fission Fission utilises the energy released when atoms split. In fission the actual energy required to split the atom is greater than the energy produced. But by creating a situation in which is possible for the high energy particles produced when the atoms split, to split other atoms, a chain reaction can take place and vast amounts of energy can be released (i.e. an atomic bomb). In a nuclear reactor this chain reaction is controlled by using graphite control rods to block the high energy particles controlling the chain reaction. The heat produced from the fission reaction is transferred through a coolant gas to a heat exchanger which heats water, creating steam and turning turbines. Nuclear fission though is very dangerous. The by-products of the process is harmful radioactive materials which is difficult to dispose of safely. Nuclear Fusion Nuclear fusion in theory is the answer to man's energy needs. In nuclear fusion atoms are fused together releasing energy. Water could be used as the fuel source, but at present the technology can only produce fusion for very short periods and even then the amount of energy required to start the reaction is far more than the energy we get out of the reaction.

Nuclear energy is used for things such as atomic bombs, hydrogen bombs and other nuclear weapons. Nuclear energy can also be used for powering electricity-generating plants all over the world. There are many arguments for and against nuclear power. Nuclear power is an inexpensive clean source of power. Others feel that because of the hazardous radiation emitted during the producing of the power and the radioactivity of the material used that nuclear power is not as good as the alternatives which are fossil fuels and solar power.(Hansen, 1993) If matter changes state or composition, it is accompanied by the production of energy. Processes such as combustion produce energy by rearranging the atoms or molecules of that substance.(Brain, 1998) An example of this is the

About the Author The Ten Types Nuclear Energy There are two types of nuclear energy, fission and fusion. Both forms of energy are stored as mass in the atoms of certain elements. This mass can be changed into energy under the proper conditions according to Albert Einstein's famous equation: where E = energy, m=mass, and c=speed of light As you will see below, both types of nuclear energy can be stored, either in the atoms of hydrogen or the atoms of radioactive elements like uranium. Therefore, nuclear is a potential form of energy. Fusion (c) 2002 Nuclear reactions occur because the new elements are more stable than the original elements. Nuclear reactions can continue changing lighter elements into heavier elements up to the element oxygen. Elements heavier than oxygen are more stable and cannot be changed into heavier elements via nuclear reactions. This is one reason that elements heavier than helium are present in the universe today, these elements being manufactured in the middle of stars like our sun. So all of the carbon atoms that we are made of and all of the oxygen atoms we breathe were made in the nuclear reactions of stars a long time ago.

To Guide Entry Introduction During the 1970’s, interest in different energy alternatives surfaced in this country. Obviously, this increase in public awareness was mainly due to our problems with foreign oil. Energy alternatives, like gas, coal, solar, wind, and nuclear, have been researched and each of their advantages and disadvantages have been examined and scrutinized. The energy alternative that is the subject of this unit is probably the most controversial, nuclear energy. One reason I chose this topic is because of the ignorances and fears of many people regarding nuclear energy. My students are the adults of tomorrow and should be given the facts on this energy source, its past record and what the possibilities and changes are for the future. The unit covers 4 to 6 weeks and is planned for use in a 9th grade Physical Science course. The unit is divided into the following sections:

THE HISTORY OF NUCLEAR ENERGY Nuclear Engineering U.S. Department of Energy DOE/NE-0088 The History of Nuclear Energy Energy from the Atom Although they are tiny, atoms have a large amount of energy holding their nuclei together. Certain isotopes of some elements can be split and will release part of their energy as heat. This splitting is called fission. The heat released in fission can be used to help generate electricity in powerplants. Uranium-235 (U-235) is one of the isotopes that fissions easily. During fission, U-235 atoms absorb loose neutrons. This causes U-235 to become unstable and split into two light atoms called fission products. The combined mass of the fission products is less than that of the original U-235. The reduction occurs because some of the matter changes into energy. The energy is released as heat. Two or three neutrons are released along with the heat. These neutrons may hit other atoms, causing more fission. A series of fissions is called a chain reaction. If enough uranium is brought together under the right conditions, a continuous chain reaction occurs. This is called a self-sustaining chain reaction. A self-sustaining chain reaction creates a great deal of heat, which can be used to help generate electricity. Nuclear powerplants generate electricity like any other steam-electric powerplant. Water is heated, and steam from the boiling water turns turbines and generates electricity. The main difference in the various types of steam-electric plants is the heat source. Heat from a self-sustaining chain reaction boils the water in a nuclear powerplant. Coal, oil, or gas is burned in other powerplants to heat the water.

Four thousand jobs were lost and the once prosperous town of Seaside quickly slipped into recession. In an effort to revive the economy in Seaside, a group of concerned citizens has lobbied the Nuclear Regulatory Commission , and convinced them that Seaside would be an ideal location for California's next nuclear power plant. The citizens of Seaside have been left with two choices: Vote to accept the power plant and all of its benefits or reject the proposal because of the negative aspects of living with the danger of a nuclear power plant in their backyard. The Task The city council of Seaside has decided to gather a team of specialists to investigate the opening of the power plant. Each specialist will present their report at a town meeting. It has been decided that the team will consist of six members: Standard Electric Board Member who wants to convince the town people that a power plant would be an economic boon in a time of recession.

How is nuclear energy produced? Chain reaction How is uranium related to energy? Uranium is an element found in nature. Used as a nuclear fuel, it is a source of energy. Uranium fuel is emissions-free, making it safe for the environment and in comparison to other fuels, only a tiny quantity is required to generate an equivalent amount of electricity. All the uranium produced by Cameco is used to generate electricity. Society depends on electricity. It wakes us up, cooks our food, keeps us warm, cools us off, runs the factories, and connects us to the Internet. We may take these conveniences for granted but many of the things we do require electricity. Electricity is a form of energy. The universe is made up of both matter and energy. Matter is all those things that have weight, or mass - rocks, trees, lakes, people, animals. Energy is harder to describe, but it is observed all the time. Energy is the force that makes things move and change. In other words, if the universe were a watch... energy would make it tick. A typical pellet of uranium weighs about 7 grams (0.24 ounces). It can generate as much energy as 3.5 barrels of oil, 17,000 cubic feet of natural gas, or 1,780 pounds of coal.

Fission is a break up of a nucleus in two or more pieces (smaller nuclei). Fusion is the opposite process: Formation of a bigger nucleus from two small nuclei. A question may arise: How two opposite processes can both produce energy? Can we make an inexhaustible souce of energy by breaking up and then fusing the same nuclei? Of course not! The energy conservation law cannot be circumvented in no way. When speaking about fusion and fission, we speak about different ranges of nuclei. Energy can only be released when either light nuclei fuse or heavy nuclei fission. To understand why this is so, let us recollect that for releasing energy the mass of initial nuclei must be greater than the mass of the products of a nuclear reaction. The mass difference is transformed into the released energy. And why the product nuclei can loose some mass as compared to the initial nuclei? Because they are more tightly bound, i.e. their binding energies are lager.

The new reactors will feature so-called passive safety systems that do not require human intervention in the case of an accident. Some will operate at sufficiently high temperatures to produce hydrogen from water as well as electricity. Experts say the new systems will be more economical to build, operate, and maintain than current generations of nuclear reactors. EVOLUTIONARY Four advanced boiling-water reactors, such as this one at the Lungmen Power Station, Taiwan, are under construction in Japan and Taiwan. TAIWAN POWER COMPANY PHOTO These new types of reactors are often described as "evolutionary" or "revolutionary." The evolutionary systems, known as generation III and III+ systems, have designs that evolved from the generation II fleet of reactors that were built in the 1970s and 1980s and continue to operate today. Generation III systems were developed in the 1990s and feature enhanced safety systems. They are more economical to build, operate, and maintain than the previous generation; two are currently in operation and another four are under construction. Generation III+ systems are evolving from the generation III systems but are not yet operational. They are actively under development and being considered in several countries for deployment over the next decade or so.

Liz Minchin reports. In an icy February day in Paris this year, Ian Hore-Lacy sat down to lunch with 200 colleagues at the annual gathering of the nuclear industry's public relations strategists. The conference ended on an optimistic note, as the European Nuclear Society News reported, "with many delegates confirming that the tide of public opinion is slowly turning in nuclear energy's favour". Speaking to The Age at the time, Hore-Lacy, the Melbourne-based head of communications for the World Nuclear Association, was feeling good about the industry's prospects. But he did have one frustration: the refusal of Australian politicians to publicly discuss, let alone consider, nuclear power as a way to generate electricity. "I think that attitude is a political dodging of the issue," Hore-Lacy said. Suddenly, all that has changed. Over the past few weeks, some of Australia's most senior politicians - including New South Wales Labor Premier Bob Carr, Prime Minister John Howard, Treasurer Peter Costello and Foreign Minister Alexander Downer - have been tripping over themselves to call for a "sophisticated" debate on nuclear power.

Nuclear Energy The Energy stored in the nucleus of an Atom and released through fission, fusion, or Radioactivity . In these processes a small amount of Mass , equal to the difference in mass before and after the reaction, is converted to energy according to the relationship E = mc-squared (m x c^2), where E is energy, m mass, and c the Speed of Light (see Relativity ). In fission processes, a fissionable nucleus absorbs a Neutron , becomes unstable, and splits into two nearly equal nuclei. In fusion processes, two nuclei combine to form a single, heavier nucleus. Fission occurs for very heavy nuclei, while fusion occurs for the lightest nuclei. Nuclear fission was discovered in 1938 by Hahn, Otto and Fritz Strassman, and was explained in 1939 by Lise Meitner and Otto Frisch. Fission energy can be obtained by bombarding the fissionable Isotope Uranium -235 with slow neutrons in order to split it. Because this reaction releases an average of 2.5 neutrons, a chain reaction is possible, provided at least one neutron per fission is captured by another nucleus and causes a second fission. In an Atomic Bomb the number of neutrons producing additional fission is greater than 1, and the reaction increases rapidly to an explosion (see

Nuclear Engineering and Health Physics Scholarship and Fellowship Program This program is designed to meet the Department of Energy's (DOE) needs for appropriately trained personnel for the maintenance and development of nuclear power technology and in research related to ongoing programs at DOE facilities. Increasing costs for graduate education, a high demand for nuclear engineers and health physicists, and the declining number of academic programs have had a negative impact on the number of well-qualified students seeking degrees in fission technologies and sciences. However, current and planned uses of fission reactors for energy generation and research support at DOE facilities, emphasize the importance of the availability of appropriately educated, highly qualified nuclear engineers and health physicists with undergraduate and advanced degrees. These fellowship and scholarship programs are designed to encourage talented students to continue their education in a related nuclear energy field. These programs will assist in preparing students for leadership roles in fission technology and will also support the broader objective of advancing fission energy through educational and research efforts.

Nuclear Overview History Facts and Figures Environment ... Electricity Generation Electricity generation using nuclear energy Overview Heat energy is produced when atoms break down and split into two or more parts. This is called atomic fission and the atoms as they break down are said to be radioactive . When they break down they produce small particles and energy, called radiation, and this is dangerous to living things. As some radioactive atoms break down they release small particles called neutrons. If these strike other radioactive atoms they make them split, releasing more neutrons. This is called a chain reaction and can result in huge amounts of energy being produced. Nuclear reactors use radioactive substances to produce heat energy that can be changed into electrical energy. The reactors control the rate of nuclear fission using rods to absorb some of the released neutrons and slow others down. The rods are called control rods and allow the fission reaction to be managed safely and to do useful work. The fuel for nuclear fission reactions is either uranium-235 or plutonium-239.

NUCLEAR ENERGY There are two paths to deriving energy from nuclear reactions - Nuclear Fission and Nuclear Fusion First, what is a Nuclear Reaction Remember that the nucleus of every atom is composed of protons ( p ) and neutrons ( n o ). If you add or subtract a nucleon to a nucleus, this is a nuclear reaction. The Forces of Nature Gravity is the force that prevents the Sun from expanding despite the fact that it is a hot gas. Gravity also keeps the Earth forever falling towards the Sun in its orbit and keeps all the people in this room in their seats. One way to look at gravity is that it is an attractive force between objects with mass Electric Force is a force felt between charged particles like electrons (e ) and protons (p ). There are both attractive and repulsive electrical forces. Like charges repel, opposite charges attract . The Electrical Force holds atoms and molecules together and is useful for all kinds of nifty gadgets that have been built in the last 150 years. Fun note: The electric force is what keeps you from falling through the chair and floor and earth and being cooked in the center of the Earth. You are suspended above your chair by the repulsive force of the protons in your body against the protons in the chair. Nuclear Force . If you think about it for a minute, the nuclei of atoms which contain protons (positively charged) and neutrons (no charge) should not be stable. All those "like" charged protons should be repelling one another and fly right out of the nucleus. Since nuclei ARE stable, it can be inferred that there is another force that is stronger than the electrical force which glues those nuclei together. This is the
