By recycling the 3 He decay into the reactor, the fusion reactor does not require materials resistant to fast neutrons. Assuming complete tritium burn-up, the reduction in the fraction of fusion energy carried by neutrons would be only about 18%, so that the primary advantage of the D-D fuel cycle is that tritium breeding is not required.
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% ...
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]
In an operating fusion reactor, part of the energy generated will serve to maintain the plasma temperature as fresh deuterium and tritium are introduced. However, in the startup of a reactor, either initially or after a temporary shutdown, the plasma will have to be heated to its operating temperature of greater than 10 keV (over 100 million ...
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [2] [3] [4]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
Earlier this year, one such reactor in China set a record for the longest sustained nuclear fusion reaction at 17 minutes. Other tests have claimed to reach a breakeven point, meaning the energy ...
ITER—the massive, proof-of-concept nuclear fusion reactor being built over the next ten years in the south of France—uses the hydrogen isotopes deuterium and tritium. The names mean exactly ...
Magnetic confinement is one of two major branches of controlled fusion research, along with inertial confinement fusion. Fusion reactions for reactors usually combine light atomic nuclei of deuterium and tritium to form an alpha particle (Helium-4 nucleus) and a neutron, where the energy is released in the form of the kinetic energy of the ...
