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.
Nuclear fusion–fission hybrid (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to the delays in the ...
Laser fusion was suggested in 1962 by scientists at LLNL. Initially, lasers had little power. Laser fusion (inertial confinement fusion) research began as early as 1965. At the 1964 World's Fair, the public was given its first fusion demonstration. [32] The device was a Theta-pinch from General Electric.
The JET tokamak in the UK produces 16 MW of fusion power - this remains the world record for fusion power until 2022 when JET sets an even higher record. Four megawatts of alpha particle self-heating was achieved. LLNL study compared projected costs of power from ICF and other fusion approaches to the projected future costs of existing energy ...
ITER's stated mission is to demonstrate the feasibility of fusion power as a large-scale, carbon-free source of energy. [89] More specifically, the project has aims to: Momentarily produce a fusion plasma with thermal power ten times greater than the injected thermal power (a Q value of 10). Produce a steady-state plasma with a Q value greater ...
Aneutronic fusion. Lithium-6 – deuterium fusion reaction: an aneutronic fusion reaction, with energy released carried by alpha particles, not neutrons. Aneutronic fusion is any form of fusion power in which very little of the energy released is carried by neutrons. While the lowest-threshold nuclear fusion reactions release up to 80% of their ...
The central concept of the Lawson criterion is an examination of the energy balance for any fusion power plant using a hot plasma. This is shown below: Net power = Efficiency × (Fusion − Radiation loss − Conduction loss) Net power is the excess power beyond that needed internally for the process to proceed in any fusion power plant.
List of fusion experiments. Appearance. Target chamber of the Shiva laser, used for inertial confinement fusion experiments from 1978 until decommissioned in 1981. Plasma chamber of TFTR, used for magnetic confinement fusion experiments, which produced 11 MW of fusion power in 1994. Experiments directed toward developing fusion power are ...
