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.
A fusion rocket is a theoretical design for a rocket driven by fusion propulsion that could provide efficient and sustained acceleration in space without the need to carry a large fuel supply. The design requires fusion power technology beyond current capabilities, and much larger and more complex rockets. Fusion nuclear pulse propulsion is one ...
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.
As of 2023, the Wendelstein 7-X reactor is the world's largest stellarator device. [3] After two successful operation phases ending in October 2018, the reactor was taken offline for upgrades. [4] [5] The upgrade completed in 2022. New fusion experiments in February 2023 demonstrated longer confinement and increased power. [6]
A Plasma Escape Plan Solved a Monumental Fusion Roadblock. To create reliable, commercial nuclear fusion on Earth, scientists need to heat up plasma inside tokamak reactors to 150 million degrees ...
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [1 ...
The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin ’s Skunk Works. [1] Its high- beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development.
This is the first attempt to make a working fusion reactor. 1939. Peter Thonemann develops a detailed plan for a pinch device, but is told to do other work for his thesis. [6] Hans Bethe provides detailed calculations of the proton–proton chain reaction that powers stars. This work results in a Nobel Prize for Physics. [7]
