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 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 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 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.
Nuclear Production Tax Credit
The Nuclear Production Tax Credit is a US federal tax credit for electricity from existing nuclear plants, created by the Inflation Reduction Act of 2022.
Nuclear program of Saudi Arabia
Saudi Arabia's civilian nuclear program: K.A.CARE, NRRC regulator, SNEHC operator, Duwaiheen tender for two 1.4 GWe reactors with CNNC, EDF, KEPCO, Rosatom bidding, no reactor built, SQP rescinded 2024, no Additional Protocol.
Nuclear propulsion
Nuclear propulsion is the use of a reactor to supply vehicle energy. It is used in mature naval systems like submarines since the 1950s and in developing spacecraft applications.
Nuclear reactor
A nuclear reactor, also called an atomic reactor, is a machine that controls a nuclear chain reaction to generate heat, producing about 9% of the world's electricity.
Nuclear Regulation Authority
The Nuclear Regulation Authority (Genshiryoku Kisei Iinkai, abbreviated NRA) is Japan's independent nuclear regulatory body, created in 2012 as an external organ of the Ministry of the Environment after Fukushima.
Nuclear Regulatory Commission
The Nuclear Regulatory Commission is the independent US agency that licenses and regulates civilian nuclear power plants and radioactive materials, taking over from the Atomic Energy Commission in 1975.
Nuclear renaissance
The nuclear renaissance is the renewed interest in building nuclear power plants since the early 2000s, driven by climate policy, energy security, and rising electricity demand.
Nuclear reprocessing
Nuclear reprocessing is the set of chemical processes, chiefly PUREX, that separate usable uranium and plutonium from spent nuclear reactor fuel so they can be recycled into new fuel.
Nuclear safeguards
Nuclear safeguards are verification measures, applied chiefly by the International Atomic Energy Agency, by which states demonstrate that nuclear material stays in peaceful use and is not diverted to weapons.
Nuclear Safety Commission of Spain
The Nuclear Safety Commission of Spain (Consejo de Seguridad Nuclear, CSN) is Spain's independent regulator for nuclear safety and radiation protection, created by law in 1980.
Nuclear Safety Directive
The Nuclear Safety Directive, adopted in 2009 and amended in 2014, is binding EU law obliging Member States to maintain nuclear safety frameworks, independent regulators, and peer reviews.
Nuclear Waste Fund
The Nuclear Waste Fund is a United States federal trust fund, created by the Nuclear Waste Policy Act of 1982 to pay for disposing of spent nuclear fuel.
Nuclear Waste Management Organization (Canada)
The Nuclear Waste Management Organization (NWMO) is a Canadian not-for-profit organization, established in 2002 under the Nuclear Fuel Waste Act to manage Canada's used nuclear fuel.
Nuclear Waste Policy Act
The Nuclear Waste Policy Act of 1982 is the US federal law directing the Department of Energy to develop geologic repositories for spent nuclear fuel and high-level waste.
