Nuclear Power Nuclear power is possibly the most contentious and emotive of all methods of energy production, due to the nature of the material involved and long term consequences of accidents. Nuclear power stations currently produce about 14% of Britain's electricity. There has been a significant drop in this figure since 2006 (around 20%) because several nuclear plants have been shut down for repairs for extended periods. Uranium is a naturally occurring radioactive element, left over from Earth's formation. It can be used in nuclear power production because if a free neutron collides with the nucleus of a Uranium atom, the nucleus splits (fission) into two smaller atoms plus one free neutron. This free neutron can then cause another fission to occur (a chain reaction). As the two new atoms weigh less than the original Uranium atom, an enormous amount of energy is also released. The energy produced by the splitting of the Uranium nucleus in the power plant (the reactor) is used as a heat source. This turns water into steam, which drives a turbine. The turbine spins a generator to produce electricity. The reactor is sealed inside concrete and steel to prevent radioactive gases and fluids leaking from the plant.

Nuclear power From New World Encyclopedia Jump to: navigation search Previous (Nuclear physics) Next (Nuclear reaction) A nuclear power station. The nuclear reactor is contained inside the cylindrical containment buildings to the right—left is a cooling tower venting non-radioactive water vapor. Nuclear power is a type of nuclear technology involving the controlled use of nuclear reactions to release energy for work, including propulsion, heat , and the generation of electricity . Nuclear energy is produced by a controlled nuclear chain reaction and creates heat—which is used to boil water, produce steam, and drive a steam turbine. The turbine can be used for mechanical work and also to generate electricity. The use of nuclear power has also engendered much debate. Critics claim that nuclear power is a potentially dangerous energy source with a limited fuel supply (compared to renewable energy), and they note the problems of storing radioactive waste, the potential for radioactive contamination by accident or sabotage, and the possibility of nuclear proliferation. Advocates claim that these risks are small and can be further reduced by the technology in new reactors, and the safety record is good when compared to other major types of power plants. In addition, they note that many renewable energy technologies have not solved the problem of their intermittent power production. Contents Use History Origins Early years ...

Credits Introduction Nuclear power is one of the most modern and dangerous forms of energy generation in use today. Since the discovery of atomic energy in the 1940�s, it has been the cause of thousands of deaths, but has also been the subject of some of the most amazing discoveries in the 20th century. At one time, the amazing amount of energy that could be released from a small amount of fuel seemed to be the answer to all of our energy problems, but today, we are able to see the dangers in this kind of energy generation. Generation Of The Electricity Nuclear Fission is the form of power generation used in power plants today. It is a slow and controlled release of energy generated by splitting atoms. Nuclear Fusion (not Fission) is the quick and dangerous release of energy produced from joining atoms. This is the destructive force that was used to kill thousands of Japanese civilians during World War II. The sun also uses fusion to release the energy we see as sunlight and feel as heat. Nuclear power is the most efficient form of energy production in use today. A tiny piece of Uranium about the size of a golf ball has the same amount of stored energy as 2,300,000 pounds of coal! That�s 19 � train cars of coal! This tremendous amount of energy is released from the Uranium in a nuclear reactor. The nuclear reactor is much like a furnace for Uranium. Within this reactor, an amazing reaction takes place which releases energy, some in the form of heat. The heat energy released is used to boil water. The boiled water is moved to a heat exchanger, which transfers the heat from the water which contacted the reactor to fresh water. The fresh water is converted to steam, and the steam turns a turbine.

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.

Glossary Nuclear Power Now Nuclear power is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. The use of nuclear power in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain. Nuclear power has important implications for our national security. Inexpensive nuclear power, in combination with fuel cell techology, could significantly reduce our dependency on foreign oil. Nuclear power plants have experienced an admirable safety record. About 20% of electricity generated in the U.S. comes from nuclear power, and in the last forty years of this production, not one single fatality has occurred as a result of the operation of a civilian nuclear power plant in the United States. In comparison, many people die in coal mining accidents every year and approximately ten thousand Americans die every year from pollution related to coal burning. The nuclear power industry generates approximately 2,000 tons of solid waste annually in the United States. In comparison, coal fueled power plants produce 100,000,000 tons of ash and sludge annually, and this ash is laced with poisons such as mercury and nitric oxide.
