Nuclear Energy Institute Science Club 4 Your Class Project How nuclear energy works When uranium atoms are split, the heat produced is called nuclear energy. This energy is converted to electricity by a nuclear power plant. Fission releases large amounts of energy (heat), which is called nuclear energy because it comes from a reaction in the nucleus of the uranium-235 atom. For uranium to be used as a fuel, its U-235 content must be increased from less than 1 percent to between 3 and 5 percent. August 2000

The Difference Between Fission and Fusion Nuclear Fission - Splitting Atoms How Fission works Energy Efficiency Radioactivity Security Issues ... Fusion Alternative The Difference between Fission and Fusion Fission and Fusion are both nuclear energy, but when people discuss nuclear power, they are usually referring to nuclear fission. This is because we have many nuclear power plants that use fission, but no one has been able to build a working fusion plant yet. The main difference between fission and fusion is that in fission, a large nucleus is split into two smaller ones, and in fusion, two nuclei are combined into one. Both processes release vast quantities of energy. (See simple animation of

Nuclear Energy, Plutonium and Radioactive Power Part 1 Nuclear Fission About the method of generating electricity by nuclear fission, a look at nuclear energy, plutonium and radioactive materials. Leave On the Lights, but Turn Off the Plutonium If sunbeams were weapons of war, we would have had solar energy centuries ago.Sir George Porter, Nobel Laureate in Chemistry Nuclear fission is the most dangerous method of generating electricity known to man, yet it could bring the captains of American industry enormous wealth even as it jeopardizes the safety of humanity. Through the massive production of weapons-grade nuclear materials, the civilian reactor program greatly enhances the risks of nuclear war, nuclear terrorism by fanatical groups, and nuclear-arms proliferation. In addition, the routine operation of nuclear power plants spreads throughout the world a vile spectrum of lethal poisons which can never be completely contained and which the environment cannot safely absorb. Fortunately, nuclear-fission power is as unnecessary as it is unjustifiedwe can meet the world's electrical needs without a single fission power plant, if we sensibly temper our energy demands. Nuclear energythat is, the energy inherent in the nuclei of atomsis a broad term encompassing fission as well as fusion energy. The only kind of nuclear power generating facilities that exist today utilize fission. Fusion, a technology that might revolutionize life on earth if scientific barriers to its achievement are breached at a competitive cost, will not happen until near the end of this century, if at all.

A single 100 watt light bulb uses about the same amount of energy as your body does. And then there's your family car, computer, television, hot water, air conditioning, dishwasher, plus the movie theatre, shopping centre, and all of society's infrastructure! The total energy used each year by an average Australian (or other citizen of the developed world) is 20 X 10 How do you think we should generate this energy? Do we need to use so much? Certainly we could and should improve our energy efficiency, for example installing insulation instead of air conditioning. However, modern society seems likely to use large amounts of energy for some time to come. Nearly 30 countries around the world use nuclear power plants to generate electricity. The USA has more than 100 nuclear power plants, nearly a quarter of the world total. France generates 75% of its electricity by nuclear reactors, although for most countries the proportion is much less. In the 1950s and '60s, there was great excitement about the potential of nuclear power, and many plants were ordered and built. Many countries in Asia and elsewhere continue to build new reactors. In Western countries, enthusiasm for nuclear power has dampened somewhat since the 1970s, though even some environmentalists concede it offers benefits.

68. Fission, Fusion, Helium 3, Nuclear, Energy, Free Energy, Alternate Energy, Elect This short Treatise explores lithium fission as a possible source of clean nuclear energy. http://www.nuenergy.org/alt/IsoLithium.htm

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

ver the past few decades, the American public has become increasingly wary of nuclear power because of concern about radiation releases from normal plant operations, plant accidents, and nuclear waste. Except for Chernobyl and other nuclear accidents, releases have been found to be almost undetectable in comparison with natural background radiation. Another concern has been the cost of producing electricity at nuclear plants. It has increased largely for two reasons: compliance with stringent government regulations that restrict releases of radioactive substances from nuclear facilities into the environment and construction delays as a result of public opposition. Partly because of these concerns about radioactivity and the cost of containing it, the American public and electric utilities have preferred coal combustion as a power source. Today 52% of the capacity for generating electricity in the United States is fueled by coal, compared with 14.8% for nuclear energy. Although there are economic justifications for this preference, it is surprising for two reasons. First, coal combustion produces carbon dioxide and other greenhouse gases that are suspected to cause climatic warming, and it is a source of sulfur oxides and nitrogen oxides, which are harmful to human health and may be largely responsible for acid rain. Second, although not as well known, releases from coal combustion contain naturally occurring radioactive materialsmainly, uranium and thorium.

SITE MAP Electricity from Nuclear Energy Nuclear energy originates from the splitting of uranium atoms in a process called fission. Fission releases energy that can be used to make steam, which is used in a turbine to generate electricity. Nuclear power accounts for approximately 19 percent of the United States' electricity production. More than 100 nuclear generating units are currently in operation in the United States. No nuclear power plants have been built since 1996. Environmental Impacts of: Natural Gas Coal Oil Hydroelectricity ... Non-Hydro Renewable Uranium is a nonrenewable resource that cannot be replenished on a human time scale. Uranium is extracted from open-pit and underground mines. Once mined, the uranium ore is sent to a processing plant to be concentrated into a useful fuel (i.e., uranium oxide pellets). This uranium enrichment process generates radioactive waste. Enriched fuel is then transported to the nuclear power plant. At the power plant, the uranium oxide pellets are bombarded with neutrons, causing the uranium atoms to split and release both heat and neutrons. These neutrons collide with other uranium atoms and to release additional heat and neutrons in a chain reaction. This heat is used to generate steam, which is used by a turbine to generate electricity.

77. Ecology.com - The Nuclear Energy Challenge As a result, the first usable electricity from nuclear fission was produced Perhaps the greatest challenge facing nuclear energy production after any http://www.ecology.com/feature-stories/nuclear-energy-challenge/sidebar.html

The Nuclear Energy Challenge by Eric McLamb document.write('Print This Page'); The atom, courtesy California Energy Commission The atom, the smallest component of any element, contains enormous energy. When it is split a process called fission, this energy is released in the forms of tremendous heat and light. It is this energy that was released on Hiroshima and Nagasaki, Japan, by two separate atom bombs in 1945 that led to the conclusion of World War II. The horrors created by those two bombs led the international community to condemn further use of atomic weapons. Still, engineers, governments and scientists realized that if the atom's energy could be controlled and harnessed, it would revolutionize the world's energy markets and provide significant electricity reserves to help meet the world's energy demands. It was even envisioned that it could one day replace the need for fossil fuels. As a result, the first usable electricity from nuclear fission was produced at the Idaho National Engineering Laboratory in 1951. A History In 1954, The Atomic Energy Act was passed to promote the peaceful use of nuclear energy. Subsequently, in 1957, the International Atomic Energy Agency (IAEA) was formed to promote peaceful use of nuclear energy and to provide international safeguards and an inspection system to ensure nuclear materials are not diverted from peaceful to military uses. It was later replaced by the Nuclear Regulatory Commission and the Energy Research and Development Administration, the latter of which became the US Department of Energy in 1977.

A Nuclear Reactor The term Nuclear Reactor means an interaction between two or more Nuclei, Nuclear Particles, or Radiation, possibly causing transformation of the nuclear type; includes, for example, fission, capture, elastic container. Reactor means the core and its immediate container. Nuclear Reactors are used to produce electricity . The numbers of Nuclear Reactor plants have grown sufficiently . Electricity is being generated in a number of ways, it can be generated by using Thermal Power. It can be employed by using two basic systems a Steam Supply System and an Electricity Generating System these two systems are related to each other. The Steam Supply System produces steam from boiling water by the burning of coals and the Electricity Generating System produces electricity by steam turning turbines. The Nuclear power plants of this century depend on a particular type of Nuclear Reaction, Fission (The splitting of a heavy nucleus like the uranium atom to form two lighter "fission ! fragments" as well as less massive particles as the Neutrons). In the Nuclear Reactors this splitting is induced by the interaction of a neutron with a fissionable nucleus. Under suitable conditions, a "chain" reaction of fission in which events may be sustained. The energy released from the fission reactions provide heat, part of which is ultimately converted into electricity. In the present day Nuclear power plants, this heat is removed from the Nuclear fuel by water that is pumped past rods containing fuel. The basic feature of the nuclear reactor is the release of a large amount of energy from each fission event that occurs in the nuclear reactors core. On the average, a fission event releases about 200 million electron volts of energy. a typical chemical reaction, on the other hand releases about one electron volt. The difference, roughly a factor of 100 million electron volts. The complete fission of one pound of uranium would release roughly the same amount of energy as!
