First plasma was obtained on NSTX on Friday, February 12, 1999 at 7:06 p.m. . Magnetic fusion experiments use plasmas composed of one or more hydrogen isotopes.For example, in 1994, PPPL's Tokamak Fusion Test Reactor produced a world-record 10.7 megawatts of fusion power from a plasma composed of equal parts of deuterium and tritium, a fuel mix likely to be used in commercial fusion power ...
Prototype for development of Commercial Fusion Reactors 1.5–2 GW Fusion output. [62] K-DEMO (Korean fusion demonstration tokamak reactor) [63] Planned: 2037? National Fusion Research Institute: 6.8 m / 2.1 m: 7 T: 12 MA ? Prototype for the development of commercial fusion reactors with around 2200 MW of fusion power: DEMO (DEMOnstration Power ...
The first Soviet fusion bomb test, RDS-6s, American codename "Joe 4", demonstrated the first fission/fusion/fission "layercake" design, limited below the megaton range, with less than 20% of the yield coming directly from fusion. It was quickly superseded by the Teller-Ulam design. This was the first aerial drop of a fusion weapon.
Its fusion reactor uses a different fuel combination, and the reactor itself is a totally different form factor from tokamaks or stellarators. (A tokamak uses a current to control the sun-hot ...
Jennifer Granholm, secretary of the U.S. Department of Energy, says that the U.S. is aiming to create a working fusion reactor by 2035.
Once fusion has begun, high-energy neutrons at about 160GK will flood out of the plasma along with X-rays, neither being affected by the strong magnetic fields. Since neutrons receive the majority of the energy from the fusion, they will be the reactor's main source of thermal energy output.
The reaction chamber of the DIII-D, an experimental tokamak fusion reactor operated by General Atomics in San Diego, which has been used in research since it was completed in the late 1980s. The characteristic torus-shaped chamber is clad with graphite to help withstand the extreme heat.
One of the ongoing research issues for commercial fusion power development is the choice of material for the plasma-facing portions of the reactor vessel, also known as the first wall. Most reactors operate at the equivalent of a high vacuum and thus demand high-strength materials to resists the inward pressure of the magnets against the empty ...
