When the time comes to actually try to make electricity from a tokamak-based reactor, some of the neutrons produced in the fusion process would be absorbed by a liquid metal blanket and their kinetic energy would be used in heat transfer processes to ultimately turn a generator.
Fusion reactors are not subject to catastrophic meltdown. [123] 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. [124] Fusion reactors operate with seconds or even microseconds worth of fuel at any moment.
Prototype for development of Commercial Fusion Reactors 1.5–2 GW Fusion output. [64] K-DEMO (Korean fusion demonstration tokamak reactor) [65] 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 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 ]
the Bremsstrahlung losses appear to make a fusion reactor using these fuels with a quasineutral, isotropic plasma impossible. Some ways out of this dilemma have been considered but rejected. [77] [78] This limitation does not apply to non-neutral and anisotropic plasmas; however, these have their own challenges to contend with.
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.
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 ...
The design requires fusion power technology beyond current capabilities, and much larger and more complex rockets. Fusion nuclear pulse propulsion is one approach to using nuclear fusion energy to provide propulsion. Fusion's main advantage is its very high specific impulse, while its main disadvantage is the (likely) large mass of the reactor.
