Energy derived from nuclear reactions; -- used at present especially of electrical power generated in atomic reactors, but encompassing also fusion energy.
The tiny nucleus at the center of the atom contains the most powerful force ever discovered. This force gives us nuclear energy, sometimes called atomic energy. The most complicated element that occurs in nature is uranium. The nuclear fuel used in nuclear power plants is a rare form of uranium called uranium-235. When the nucleus of a uranium-235 atom is struck by a neutron (see atom), it breaks apart and more neutrons shoot out. These new neutrons strike other uranium nuclei, causing them to split and give out still more neutrons. In this way, more and more nuclei split, and many atoms give up their energy at once. If the action is not controlled, a tremendous explosion takes place – the explosion that powers nuclear weapons. Nuclear energy can be controlled to provide us with power. In a nuclear power plant, control rods are lowered into the reactor to keep the reaction in check. But the uranium still gets very hot, and so a coolant, a liquid or a gas, moves through the reactor. When the hot coolant leaves the reactor, it goes to a boiler to make steam. It is this steam that powers generators to make electricity for our homes and factories.
The energy liberated by a nuclear reaction (fission or fusion) or by spontaneous radioactivity.
Energy that comes from splitting atoms of radioactive materials, such as uranium, which leave behind radioactive wastes.
The energy used or produced in changing the composition of the atomic nucleus.
splitting radioactive uranium atoms to create heat energy
Nuclear energy refers to the energy consumed or produced in modifying the composition of the atomic nucleus. Nuclear energy also powers electricity-generating plants in countries throughout the world. It is seen by many as the source of inexpensive, clean power; but, because of the hazardous radiation emitted in producing that power and the radioactivity of the materials used, others feel that it may not be a viable energy alternative to the use of fossil fuels or solar energy.
Nuclear energy is a relatively new energy form which utilises the energy which holds two atoms together. Splitting them produces energy which we call nuclear power. The radioactive substance uranium is used for this purpose and, when it is split, it produces other radioactive fission products. The principal environmental problems when it comes to nuclear energy are the handling and emission of radioactive substances. Because of the disastrous effect these substances have on living organisms (molecules in live cells are changed, thereby producing different effects such as cancer and genetic defects), nuclear power is strictly regulated in most countries. Most emissions of radioactive substances take place in connection with faults and catastrophes. Another threat with nuclear power is that the waste can be reprocessed to produce plutonium, which is used in nuclear weapons.
The energy released by a nuclear reaction, and harnessed as a source of power. Also called atomic energy.
The generation of energy by nuclear fission of fissionable nuclei.
energy produced by breaking up atoms ..... return
the energy stored in the nucleus of an atom which can be released upon fission.
The energy released during nuclear burning. The term also refers to the energy released by the breakup (fission) of very heavy atomic nuclei, such as uranium-235 and plutonium-239.
Energy developed through nuclear radiation produced in reactors. Due to the numerous high risks and prohibitive costs, nuclear power is neither an alternative to fossil fuels nor a solution to climate change. Back up
the heat energy produced by the process of nuclear fission within a nuclear reactor or by radioactive decay.
Energy produced from changes in atomic nuclei
the energy released when the nucleus of an atom is split apart
The energy liberated by a nuclear reaction (fission or fusion) or by radioactive decay.
Nuclear energy is released by breaking apart or smashing together atoms. This is the energy which powers the sun. Nuclear Power
Energy produced from the splitting of atoms.
Energy obtained from nuclear fission and fusion.
Nuclear energy relies on the splitting of uranium atoms in a process called fission, which generates heat for producing steam that then turns a turbine to produce electricity. While nuclear power plants do not emit air pollutants, nuclear wastes and abandoned uranium mines pose health risks from radiation for as long as 250,000 years if not contained properly.
Energy released when atomic nuclei undergo a nuclear reaction such as the spontaneous emission of radioactivity, nuclear fission, or nuclear fusion.
Energy released by radioactive decay, through a nuclear reaction, or in the course of nuclear fission. A synonym for nuclear power. Synonym: atomic energy. Synonym: (obsolete) tomic energy.
Energy produced by particles such as those in the sun.
A form of potential energy in the nuclei of atoms and released by fission (the splitting of nuclei of heavy atoms such as uranium) or by fusion (the combining of nuclei of light atoms such as hydrogen). See Fission, Fusion.
Power obtained by splitting heavy atoms (fission) or joining light atoms (fusion). A nuclear energy plant uses a controlled atomic chain reaction to produce heat. The heat is used to make steam run conventional turbine generators.
energy released during a nuclear reaction as a result of fission or fusion.
Energy, usually in the form of heat or electricity, produced by the process of nuclear fission within a nuclear reactor. The coolant that removes the heat from the nuclear reactor is normally used to boil water, and the resultant steam drives steam turbines that rotate electrical generators.
energy or power produced by nuclear reactions (fusion or fission).
One way of providing the heat for a power station is to use a metal called uranium. When small particules of uranium (called atoms ) split apart, they release a lot of heat
Nuclear energy is energy released from the atomic nucleus. It follows the conversion of its mass to energy consistent with Albert Einstein's formula E=mc² in which E = Energy, m = Mass, and c = The speed of light (a physical constant). However, the mass-energy equivalence does not explain how the reaction occurs, but rather nuclear forces do.
