v. t. e. Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.
Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium (2 H) and tritium (3 H). Energy is deposited in the target's outer layer, which explodes outward.
Nuclear fusion occurs when two atoms of a light element such as hydrogen are heated and fused together to form a heavier element such as helium. In order for that process to occur, the atoms must ...
Date (s) of construction. 2013–2034. ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [ 2 ][ 3 ][ 4 ]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Sun, [2] whereas the CNO cycle, the other known reaction, is suggested by theoretical models to dominate in ...
Nuclear fusion reaction of two helium-4 nuclei produces beryllium-8, which is highly unstable, and decays back into smaller nuclei with a half-life of 8.19 × 10 −17 s, unless within that time a third alpha particle fuses with the beryllium-8 nucleus [3] to produce an excited resonance state of carbon-12, [4] called the Hoyle state, which ...
CNO cycle. Logarithm of the relative energy output (ε) of proton–proton (p–p), CNO, and triple-α fusion processes at different temperatures (T). The dashed line shows the combined energy generation of the p–p and CNO processes within a star. The CNO cycle (for carbon – nitrogen – oxygen; sometimes called Bethe–Weizsäcker cycle ...
