Marketing Nuclear Energy There are two types of nuclear energy, fission and fusion. 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.

This is quite a long page. Although it is designed to be read sequentially, a menu is provided in order that you can access any particular section quickly and easily. Introduction. Isotopes and Half-life. Fission in Uranium-235. Chain Reactions. ... Nuclear Power Stations. Introduction. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation E = mc The idea that there might be a way to get at the energy locked up in an atom's mass took time to catch on. Einstein himself thought it would never happen, and in an address given in England in 1933 the eminent atomic physicist and discoverer of the nucleus of the atom, Ernest Rutherford, said: "The energy produced by the breaking down of the atom is a very poor kind of thing. Anyone who expects a source of power from the transformation of these atoms is talking moonshine." However, within 10 years the world's first nuclear reactor had been built and by the mid-1950s nuclear power stations started supplying electrical power for industrial and domestic use.

29. Nuclear Energy Is The Most Certain Future Source. Discussion and FAQ from the Formal Reasoning Group (FRG) about nuclear energy sustainability. http://www-formal.stanford.edu/jmc/progress/nuclear-faq.html

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. A major advantage of nuclear energy (and also of solar energy) is that it doesn't put carbon dioxide (CO2) into the atmosphere. How much of an advantage depends on how bad the CO2 problem turns out to be.

Jon Stone Introduction Only 30 years ago, nuclear energy was an exotic, futuristic technology, the subject of experimentation and far fetched ideas. Today, nuclear energy is America's second largest source of electric power after coal. More than 110 nuclear energy plants supply more electricity than oil, natural gas or hydropower. Since 1973, they have saved American consumers approximately $44 billion, compared to the other fuels that would have been used to make electricity. Since our electricity system is interconnected, practically every American gets some electricity from nuclear energy. In addition to the economic benefits achieved through the use of nuclear energy, there are environmental benefits as well. There are, however, various drawbacks caused by the production of electricity through nuclear power. Although there are various risks involved when using nuclear energy as a source of power, we argue that the benefits greatly outweigh any potential problems that may arise. Nuclear Reactors and Their Fuel Cycles The use of nuclear reactors to generate electricity continues to increase all over the world. By December of 1979, about 128,000 million watts were being generated by 249 reactors operating in 22 countries.

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.

The most common use of nuclear reactors is for the generation of electrical power (see Nuclear power ) and for the power in some ships (see Nuclear marine propulsion ). This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines . There are also other less common uses as discussed below. Contents How it works Fission Heat generation Cooling ... edit How it works Main article: Nuclear reactor physics An induced nuclear fission event. A neutron is absorbed by the nucleus of a uranium-235 atom, which in turn splits into fast-moving lighter elements (fission products) and free neutrons. Though both reactors and nuclear weapons rely on nuclear chain reactions, the rate of reactions in a reactor is much slower than in a bomb. Just as conventional power stations generate electricity by harnessing the thermal energy released from burning fossil fuels , nuclear reactors convert the thermal energy released from nuclear fission edit Fission When a large fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron , it may undergo nuclear fission. The heavy nucleus splits into two or more lighter nuclei, releasing

Nuclear Synthesis and Nuclear Medicine Nuclear Fission and Nuclear Fusion Nuclear Fission Nuclear Fusion Nuclear Fission The graph of binding energy per nucleon suggests that nuclides with a mass larger than about 130 amu should spontaneously split apart to form lighter, more stable, nuclides. Experimentally, we find that spontaneous fission reactions occur for only the very heaviest nuclides those with mass numbers of 230 or more. Even when they do occur, these reactions are often very slow. The half-life for the spontaneous fission of U, for example, is 10 years, or about two million times longer than the age of our planet! We don't have to wait, however, for slow spontaneous fission reactions to occur. By irradiating samples of heavy nuclides with slow-moving thermal neutrons it is possible to induce fission reactions.

39. Population And Energy Resources nuclear energy fission and fusion, renewable energy resources hydroelectric, solar, wind, wave, tidal, geothermal, biomass, etc. Even though renewable resources will http://www.fusion-eur.org/fusion_cd/popu.htm

CONTROLLED FUSION : THE ENERGY OPTION FOR THE 21 st CENTURY World Population and Energy Needs Reasonable estimates indicate that the world population will be around 10 billion in the middle of the 21 st century. In 1990, annual per capita primary energy consumption was 2.2 x 10 Joules or 5.1 toe (tonnes of oil equivalent) in the industrialized countries - ten times more than in developing countries. In 2050, world primary energy consumption could be anything from two to three times its current level, depending on which energy demand scenario is chosen (see the table below). Most of this demand will have to be met by : fossil fuels (mainly coal, because crude oil and natural gas reserves will be greatly depleted), nuclear energy : fission and fusion, renewable energy resources : hydroelectric, solar, wind, wave, tidal, geothermal, biomass, etc. Even though renewable resources will probably be able to meet a greater proportion of the World's energy requirements than they do at present, experts agree that they will not be able to satisfy the total demand. New energy options must therefore be developed - systems which are optimally safe, environment-friendly and economical. Controlled thermonuclear fusion is one of these rare options. Fusion is the process by which the nuclei of light atoms (such as hydrogen) combine, or fuse, to form heavier elements. Temperatures of around 100 000 000 degrees C are needed to overcome the electrostatic repulsion between positively-charged nuclei and thus bring them close enough together for fusion reactions to occur at a sufficient rate. At these temperatures, the gas becomes a plasma (the ions and electrons form a macroscopically neutral fluid) and obviously cannot be in contact with material walls. The fusion power plant design based on a tokamak (the most performing device) uses magnetic fields to keep the plasma thermally insulated from the reactor walls. The volume of plasma, in such device, would be about 1000 m
