This article is about the primary issues upon which people differ in their assessments as to the value, role and relative safety of nuclear power. For nuclear energy policies by nation, see Nuclear energy policy. For public protests about nuclear power, see Anti-nuclear movement. For public support for nuclear energy, see Pro-nuclear movement.
The nuclear power debate is a long-running controversy[2][3][4][5][6][7][8] about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries

Nuclear power is the use of nuclear reactions that release nuclear energy[5] to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. 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.
Owing, fundamentally, to the control on the power or heat increase, that is inherent to the slow delayed critical fission process,[6] Fission-electric power stations and engines have and continue to be built, as an alternative to the dominant fossil-fuel power systems of the world. Fission-electricity is one of the leading low carbon power generation methods of producing electricity, and in terms of total life-cycle greenhouse gas emissions per unit of energy generated, has emission values lower than renewable energy when the latter is taken as a single energy source.[7][8] A 2014 analysis of the carbon footprint literature by the Intergovernmental Panel on Climate Change (IPCC) reported that the embodied total life-cycle emission intensity of fission electricity has a median value of 12 g CO2eq/kWh which is the lowest out of all commercial baseload energy sources.[9][10
