Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of …

Aug 21, 2023 · Nuclear fuel—uranium Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal …

Nov 28, 2025 · There are two ways of releasing nuclear energy: fission and fusion. Nuclear power provides almost 15 percent of the world’s electricity. The first nuclear power plants, which were small …

Aug 19, 2025 · When the electricity is made from atoms splitting apart, it's called nuclear energy. All power plants convert heat into electricity using steam. At nuclear power plants, the heat to make the …

Nov 11, 2025 · Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when …

Nuclear power, the use of sustained nuclear fission to generate heat and electricity, provides around 6 percent of the world's energy.

4 days ago · Nuclear technology uses the energy released by splitting the atoms of certain elements. It was first developed in the 1940s, and during the Second World War research initially focused on …

Nuclear power plants generate electricity by using controlled nuclear fission chain reactions to heat water and produce steam that powers turbines. Nuclear is often labeled “clean” energy because no …

Nuclear energy is a carbon-free and extremely energy dense resource that produces no air pollution. Nuclear reactions produce large amounts of energy in the form of heat.

Jun 26, 2025 · Start here to learn more about nuclear power's capabilities and limitations. You'll learn about different types of nuclear reactors, reprocessing, thorium, fission vs. fusion, and nuclear waste.
