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.
In other words, if the homogenous deuterium fuel was theoretically replaced with a 1:1 mix of deuterium and tritium, the fusion reaction would have created an energy output 1.05 times the energy used to start the reaction. JT-60U was not equipped to utilize tritium, as it would add extensive costs and safety risks.
Even when working perfectly, plasma confinement at fusion temperatures, the so-called "fusion triple product", continued to be far below what would be needed for a practical reactor design. Through the mid-1980s the reasons for many of these problems became clear, and various solutions were offered.
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% ...
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 ...
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 ...
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 ]
One rotating magnetic field pulse of the PFRC-2 device during an experiment. The Princeton Field Reversed Configuration (PFRC) is a series of experiments in plasma physics, an experimental program to evaluate a configuration for a fusion power reactor, at the Princeton Plasma Physics Laboratory (PPPL).
