Extractions: Atoms Name: 6.5 To investigate and understand that all matter is made up of atoms, including parts, elements, etc. Electric Forces between the negative electrons attracting to the positive nucleus help to hold the electrons in place. A great deal of force is needed to keep the repeling protons in the nucleus together. This force is called strong nuclear force. When the nucleus of an atom splits, the released energy is called nuclear energy. The splitting of an atom is known as fission.

Extractions: The Nuclear Ignition Facility will allow the U.S. to keep testing nuclear weaponsand perhaps undermine treaties on global arms proliferation. it's promoted as a path to clean, boundless fusion energy. but a prominent science writer explains why this claim is dubious. by Keay Davidson A major new nuclear weapons project is being sold to the public as a potential source of boundless, clean, affordable commercial energy. In fact, its relevance to world energy needs is debatable, while its main goalto help U.S. scientists maintain a huge nuclear arsenal after the Cold Waris all too clear. The proposed National Ignition Facility would house a laser as big as a football field, located at Lawrence Livermore National Laboratory east of San Francisco. The laser would blast tiny pellets of nuclear fuel to trigger miniature thermonuclear explosions inside a sealed chamber. In this way, weapons researchers could simulate bomb blasts"virtual" nuclear explosions, one might call themin order to continue honing their nuclear skills after tests using real bombs are banned by international treaty. The superlaser would cost $1.1 billion ($1.8 billion if you include long-term operational costs) and is planned for construction starting in 1997, pending final approval from the Department of Energy. If built, the National Ignition Facility would be the crown jewel of a post-Cold War nuclear weapons complex that is slated to include several other costly nuclear-simulation devices at the nation's main nuclear weapons labs: Lawrence Livermore in California and the Los Alamos and Sandia laboratories in New Mexico. The nuclear-simulation program (technically known as Science Based Stockpile Stewardship) "should enable the United States to. . .remain an acknowledged nuclear power without underground testing," according to an official summary of a 1994 Sandia conference on the project.

Nuclear Energy An Overview
This page is an over view of nuclear power. There are two fundamental ways to release energy from nuclear reactions fission and fusion of atomic nuclei.
http://www.energy.ca.gov/nuclear/overview.html

Extractions: 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. 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.

Extractions: Nuclear Fusion Basics Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy to sustain life on earth. For energy production on earth different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two heavy forms (isotopes) of Hydrogen - Deuterium (D) and Tritium (T); eventually reactions involving just Deuterium or Deuterium and Helium ( He) may be used. Most suitable fusion reaction. At the temperatures required for the D-T fusion reaction - over 100 Million deg. C - the fuel has changed its state from gas to PLASMA. In a plasma, the electrons have been separated from the atomic nuclei (usually called the "ions"). Understanding plasma required major developments in physics. Plasmas are now used widely in industry, especially for semi-conductor manufacture. A vast, new source of energy.

Extractions: Web posted at: 8:59 p.m. EST (0159 GMT) From Correspondent Cynthia Tornquist NEW YORK (CNN) Americans are losing patience with nuclear fusion, once considered a promising energy source of the future. The Tokamak Fusion Reactor at the Princeton Plasma Physics Laboratory one of the world's most powerful experimental fusion reactors illustrates the point. No fusion reactor has ever achieved a self-sustaining burn of nuclear fuel, although the Princeton reactor set a record in 1994 by producing nearly 11 million watts of fusion power for about one second. The reactor has been shut down for financial reasons. Some scientists believe its demise is a shortsighted decision that jeopardizes future hopes of generating inexhaustible energy from fusion. "My belief is the RFRT [Princeton reactor] is being shut down prematurely," physicist Robert Budny said. "It has a lot more potential." Fusion is the process that powers the sun. It occurs when atoms, usually hydrogen ions in a gas plasma, collide at high temperatures and fuse. The heat energy released can be converted to electricity.

http://www.fusion.org.uk/focus/

Extractions: Fusion power: Safe and clean FUSION power offers the potential of an almost limitless source of energy for future generations but it also presents some formidable scientific and engineering challenges. It is called 'fusion' because it is based on fusing light nuclei such as hydrogen isotopes to release energy. The process is similar to that which powers the sun and other stars. Effective energy-producing fusions require that gas from a combination of isotopes of hydrogen - deuterium and tritium - is heated to very high temperatures (100 million degrees centigrade) and confined for at least one second. One way to achieve these conditions is to use magnetic confinement. The most promising configuration at present is the tokamak, a Russian word for a torus-shaped magnetic chamber. See an animated schematic of the fusion reaction Much of the early work on fusion was undertaken by universities, before being centered at Harwell and Aldermaston. The original large-scale experimental fusion device on which British physicists worked during the 1940s and 50s was housed in a hangar at Harwell. The device called

Extractions: 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 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?

Extractions: 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 Nuclear binding energy = D mc Nuclear Structure Concepts ...

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

http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/fusion.html

Extractions: Nuclear Fusion If light nuclei are forced together, they will fuse with a yield of energy because the mass of the combination will be less than the sum of the masses of the individual nuclei. If the combined nuclear mass is less 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 lighter nuclei, and that decrease in mass comes off in the form of energy according to the Einstein relationship . For elements heavier than iron, fission will yield energy. For potential nuclear energy sources for the Earth, the deuterium-tritium fusion reaction contained by some kind of magnetic confinement seems the most likely path. However, for the fueling of the stars , other fusion reactions will dominate. Fusion concepts ...
