Energy is what holds the nucleus together. There is a huge amount of power in an atoms dense nucleus. In fact, the power that holds the nucleus together is officially called the "strong force. Nuclear energy can be used to create electricity, but it must first be released from the atom. A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity. The heat created by nuclear fission warms the reactors cooling agent. Rods of material called nuclear poison can adjust how much electricity is produced. About 15 percent of the worlds electricity is generated by nuclear power plants.

Nuclear Food: Uranium Uranium is the fuel most widely used to produce nuclear energy. Although some of the uranium the United States uses is mined in this country, most is imported. Nuclear Energy and People Chernobyl. Comanche Peak Nuclear Power Plant, Unit 2. Protectingtheenvironment. Nuclear energy is America’s largest source of clean-air, carbon-free electricity, producing no greenhouse gases or air pollutants. The industry’s commitment to the environment extends to protecting wildlife and their habitats.

Environmental Benefits and Issues Nuclear power plants aid compliance with the Clean Air Act of 1970, which set standards to improve the nation's air quality. Using more nuclear energy gives states additional flexibility in complying with clean-air requirements. Clean Electricity for Transportation Research is under way to reduce air emissions from the transportation sector by developing electric vehicles that can run farther and longer between charges. Clean electricity from nuclear plants can make these vehicles truly "clean. " Climate Change Initiatives Federal, state and local policymakers increasingly recognize nuclear energy's contribution to meeting growing electricity demand while reducing greenhouse-gas emissions.

Ecology Life-Cycle Emissions Analyses. Nuclear & Uranium. Energy In Brief Articles What is the status of the U.S. nuclear industry? There are currently 104 operable commercial nuclear reactors at 65 nuclear power plants. Since 1990, the share of the nation's total electricity supply provided by nuclear power generation has averaged about 20%, with increases in nuclear generation that have roughly tracked the growth in total electricity output See all Energy in Brief articles › Nuclear Power Explained Use of nuclear power In 2011, U.S. nuclear plants generated 790 billion kilowatthours from 104 commercial nuclear generating units.

Nuclear power and the environment The main environmental concerns for nuclear power are radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes.

Nuclear power. Nuclear power, or nuclear energy, is the use of exothermic nuclear processes,[1] to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest.

There is an ongoing debate about nuclear power.[10][11][12] Proponents, such as the World Nuclear Association, the IAEA and Environmentalists for Nuclear Energy contend that nuclear power is a safe, sustainable energy source that reduces carbon emissions.[13] Opponents, such as Greenpeace International and NIRS, contend that nuclear power poses many threats to people and the environment.[14][15][16] Use Nuclear power installed capacity and generation, 1980 to 2010 (EIA).
