Definitions for nuclear power
This page provides all possible meanings and translations of the word nuclear power
atomic power, nuclear power(noun)
nuclear energy regarded as a source of electricity for the power grid (for civilian use)
Power, especially electrical power, obtained using nuclear fission or nuclear fusion
A nation that possesses nuclear weapons
Nuclear power is the use of sustained exothermic nuclear processes to generate heat and electricity. The term includes the use of exothermic nuclear fission, nuclear decay and nuclear fusion reactions. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear power in the 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. As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power sources such as the Sun, remains an area of active physics and engineering research. Nuclear power stations, that is excluding the contribution from naval nuclear reactors, provided about 5.7% of the world's energy and 13% of the world's electricity, in 2012. In 2013, the IAEA report that there are 437 operational nuclear power reactors, in 31 countries. In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors. There is an ongoing debate about the use of nuclear energy. 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. Opponents, such as Greenpeace International and NIRS, contend that nuclear power poses many threats to people and the environment.
