Nuclear electric rocket
A nuclear electric rocket, also called nuclear electric propulsion (NEP), is a spacecraft propulsion system in which a fission reactor generates electricity that powers ion or Hall thrusters.
Nuclear emergency preparedness
Nuclear emergency preparedness is the set of plans and exercises by which governments and nuclear facility operators protect the public in a nuclear or radiological emergency, guided by IAEA standards.
Nuclear Energy Agency
The Nuclear Energy Agency (NEA) is an OECD intergovernmental agency, founded in 1958 and based near Paris, promoting cooperation on nuclear safety, science, and law.
Nuclear Energy Agency of Japan
The Nuclear Energy Agency of Japan, formally the Japan Atomic Energy Agency (JAEA), is Japan's national nuclear research and development agency, created in 2005 by merging two institutes.
Nuclear Energy Institute
The Nuclear Energy Institute is the policy organization of the United States commercial nuclear energy industry, founded in 1994 and based in Washington, DC, promoting nuclear power through policy advocacy.
Nuclear engineering
Nuclear engineering is the branch of engineering concerned with applying nuclear reactions and radiation, most prominently the design, operation, and safety of nuclear fission reactors and their fuel cycles.
Nuclear explosion
A nuclear explosion releases enormous energy almost instantly from splitting or joining atomic nuclei, first demonstrated in the Trinity test in New Mexico in 1945.
Nuclear football
The nuclear football, officially the Presidential Emergency Satchel, is a briefcase of nuclear war plans carried by a military aide so the US president can authorize a strike anywhere.
Nuclear fuel
Nuclear fuel, also called atomic fuel, is the material that sustains a controlled fission chain reaction in a nuclear reactor, usually ceramic pellets of enriched uranium dioxide in metal tubes.
Nuclear fuel fabrication
Nuclear fuel fabrication is the final front-end step of the nuclear fuel cycle: enriched uranium is made into uranium dioxide pellets, sealed in fuel rods, and assembled for reactor cores.
Nuclear Fuel Services
Nuclear Fuel Services (NFS) is a nuclear fuel fabrication company in Erwin, Tennessee, owned by BWX Technologies, supplying fuel for all U.S. naval reactors since 1957.
Nuclear graphite
Nuclear graphite is high-purity synthetic graphite used in nuclear reactors as a neutron moderator and often reflector, slowing fast neutrons to thermal energies that sustain the fission chain reaction.
Nuclear gravity bomb
A nuclear gravity bomb is a nuclear weapon dropped from an aircraft and falling under gravity without propulsion, in US service as the B61 family since 1968.
Nuclear holocaust
A nuclear holocaust is the destruction of human civilization by large-scale nuclear war. It has never occurred; Hiroshima and Nagasaki in 1945 remain the only wartime use.
Nuclear Hydrogen Initiative
The Nuclear Hydrogen Initiative (NHI) was a Department of Energy research program established in 2003 to develop large-scale hydrogen production from nuclear energy; it was terminated at the end of fiscal year 2009.
Nuclear Industry Association
The Nuclear Industry Association, formerly the British Nuclear Industry Forum, is the UK's civil nuclear trade association, representing over 340 member companies and campaigning for nuclear power.
Nuclear Installations Inspectorate
The Nuclear Installations Inspectorate (NII) was the United Kingdom's regulator for licensing and inspecting nuclear installations from 1960 until 2011, when its functions passed to the Office for Nuclear Regulation.
Nuclear marine propulsion
Nuclear marine propulsion, also called naval nuclear propulsion, uses a shipboard nuclear reactor to drive a vessel's turbines, freeing it from refueling and, for submarines, from air.
Nuclear meltdown
A nuclear meltdown, also called a core melt accident, is a severe reactor accident in which lost cooling lets decay heat damage and melt the reactor fuel.
Nuclear moratorium
A nuclear moratorium is a government decision to suspend nuclear power plant construction or operation, usually after an accident or referendum, as in Austria, Italy, and Germany.
Nuclear navy
A nuclear navy propels its ships and submarines with onboard nuclear reactors; the United States Navy created the first one in the 1950s under Hyman G. Rickover.
Nuclear power
Nuclear power, also called fission power, is electricity generation from controlled fission chain reactions, supplying about 10% of the world's electricity from 417 reactors in 2024.
Nuclear power by country
Nuclear power by country describes the world's 442 nuclear reactors in 31 countries, which generate about 9% of global electricity, led by the United States, France, and China.
Nuclear Power Corporation of India
Nuclear Power Corporation of India (NPCIL) is a Government of India public sector company under the Department of Atomic Energy, incorporated in 1987 to operate the country's commercial nuclear power plants.
Nuclear power for AI data centers
Nuclear power for AI data centers is the wave of nuclear purchase agreements by US hyperscalers Microsoft, Google, Amazon, and Meta, beginning with Microsoft's 2024 Three Mile Island restart deal.
Nuclear power in France
Nuclear power in France is the country's largest electricity source, from a fleet of 57 EDF reactors at 18 stations that produced 361.7 TWh in 2024, about 67% of generation.
Nuclear power in India
Nuclear power in India, or nuclear energy in India, comes from 24 reactors with 8,880 MW capacity, supplying about 3.1% of electricity, with a 100 GW target for 2047.
Nuclear power in the United Kingdom
Nuclear power in the United Kingdom began at Calder Hall in 1956 and today runs nine reactors at five sites, generating about 12% of UK electricity.
Nuclear power in the United States
Nuclear power in the United States is electricity generation from commercial fission reactors, 94 reactors at 54 plants in 2024 supplying about 19% of US power.
Nuclear power plant
A nuclear power plant is an electricity generating station that uses heat from a controlled nuclear fission chain reaction to boil water into steam, driving turbine generators.
