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 ...
With better conditions for fusion in the plasma, the reactor performance increases. [23] Initial use of lithium in 1990s was motivated by a need for a low-recycling PFC. In 1996, ~ 0.02 grams of lithium coating was added to the PFC of TFTR, resulting in the fusion power output and the fusion plasma confinement to improve by a factor of two.
Prototype for development of Commercial Fusion Reactors 1.5–2 GW Fusion output. [61] K-DEMO (Korean fusion demonstration tokamak reactor) [62] 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 ...
Fusion reactors are not subject to catastrophic meltdown. [121] It requires precise and controlled temperature, pressure and magnetic field parameters to produce net energy, and any damage or loss of required control would rapidly quench the reaction. [122] Fusion reactors operate with seconds or even microseconds worth of fuel at any moment.
As of 2023, the Wendelstein 7-X reactor is the world's largest stellarator device. [3] After two successful operation phases ending in October 2018, the reactor was taken offline for upgrades. [4] [5] The upgrade completed in 2022. New fusion experiments in February 2023 demonstrated longer confinement and increased power. [6]
The Large Helical Device (大型ヘリカル装置, Ōgata Herikaru Sōchi) (LHD) is a fusion research device located in Toki, Gifu, Japan.It is operated by the National Institute for Fusion Science, and is the world's second-largest superconducting stellarator, after Wendelstein 7-X.
A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas. The Field-Reversed Configuration reactor ARTEMIS in this study was designed with an efficiency of 75% ...
The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development.
