The biggest advance in fusion came in late 2022, when researchers at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California achieved the first fusion ignition ...
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 ]
Researchers at this Livermore, Calif., facility had spent more than 13 years trying and failing to attain fusion ignition, meaning that the reaction outputs more energy than scientists put into it.
Deuterium–tritium fusion (DTF) is a type of nuclear fusion in which one deuterium (2 H) nucleus (deuteron) fuses with one tritium (3 H) nucleus (triton), giving one helium-4 nucleus, one free neutron, and 17.6 MeV of total energy coming from both the neutron and helium. It is the best known fusion reaction for fusion power and thermonuclear ...
Scientists at Lawrence Livermore National Laboratory say they've produced a nuclear fusion reaction that generated more energy than it required to ignite.
Performance was gradually improved until, as of 2024, the fusion energy routinely exceeded 2 MJ. [31] To be useful for energy production, a fusion facility must produce fusion output at least an order of magnitude more than the energy used to power the laser amplifiers – 400 MJ in the case of NIF.

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 ...
Andrea Lynn "Annie" Kritcher is an American nuclear engineer and physicist who works at the Lawrence Livermore National Laboratory. She was responsible for the development of Hybrid-E, a capsule that enables inertial confinement fusion. She was elected Fellow of the American Physical Society in 2022.
