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 ]

December 21, 2023 at 1:14 AM. ... Nuclear fusion, the reaction that powers the sun and other stars, involves smashing two or more atoms together to form a denser one, in a process that releases ...
Last year, scientists using laser beams at a U.S. national lab in California repeated a fusion breakthrough called ignition where for an instant the amount of energy coming from the fusion ...
The campaign officially ended in September 2012, at about 1 ⁄ 10 the conditions needed for ignition. [ 9 ] [ 10 ] Thereafter NIF has been used primarily for materials science and weapons research. In 2021, after improvements in fuel target design, NIF produced 70% of the energy of the laser, beating the record set in 1997 by the JET reactor ...
Though fuel was added to the fire by the U.S. achieving fusion ignition in December of 2022, realizing the promise of nuclear fusion still faces many engineering and technological obstacles.
As of 2022, the record for energy production using nuclear fusion is held by the National Ignition Facility reactor, which achieved a Q of 1.5 in December 2022. [15] Beyond just heating the plasma, the total electricity consumed by the reactor and facilities will range from 110 MW up to 620 MW peak for 30-second periods during plasma operation ...
The U.S. Department of Energy officially announced a breakthrough in nuclear fusion on Tuesday that puts the world one step closer to harnessing an abundant energy source free from carbon ...
