Experiments in 2020 and 2021 yielded the world's first burning plasmas, in which most of the plasma heating came from nuclear fusion reactions. [11] This result was followed on August 8, 2021 by the world's first ignited plasma, in which the fusion heating was sufficient to sustain the thermonuclear reaction.
In 1972, John Nuckolls wrote a paper predicting that compressing a target could create conditions where fusion reactions are chained together, a process known as fusion ignition or a burning plasma. [2] On August 8, 2021, the NIF at Livermore National Laboratory became the first ICF facility in the world to demonstrate this (see plot).
If all goes to plan, Virginia will be the site of the world’s first grid-scale nuclear fusion power plant, ... December 18, 2024 at 6:53 AM. If all goes to plan, ...
Commonwealth Fusion Systems in 2021 tested successfully a 20 T magnet making it the strongest high-temperature superconducting magnet in the world. Following the 20 T magnet CFS raised $1.8 billion from private investors. General Fusion began developing a 70% scale demo system. [69] In 2018, TAE Technologies' reactor reached nearly 20 M°C. [126]

Kritcher had designed an August 2021 NIF experiment that produced a record 1.3MJ of fusion energy using 1.9 MJ of inputted laser energy—a success that came thanks to tweaks including shifting ...
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]
That experiment briefly achieved what's known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to t US scientists repeat fusion ignition ...
