(.#501).- The world's largest experimental nuclear fusion reactor.
The world's largest experimental nuclear fusion reactor.
March 6, 2020.
This is a titanic project in development: the world's largest experimental nuclear fusion reactor is being manufactured in France.
The concrete buildings have just been completed, the “Tokamak” reactor can therefore be assembled there, in order to produce energy in 2025. The challenge is daunting: to magnetically confine the extreme melting conditions found in the heart of the Sun, but in a vacuum reactor. It will be done with an almost infinite energy, clean and much less dangerous than that of nuclear power plants, because in the event of problem, the plasma used returns to its initial stage: the harmless hydrogen which one finds in water.
1- A fuel composed of deuterium and tritium (hydrogen atoms) is injected into the vacuum chamber. Then an electric current is sent into this mixture.
2- 18 superconductive electromagnets, a million times more powerful than the earth's magnetic field push and compress the mixture inside the vacuum chamber.
3- Electric tension and pressure tear apart electrons from atoms. This forms a soup of particles: plasma, a state of matter where particles interact with each other.
4- The plasma at 10 million degrees is heated to 150 million degrees thanks to radio waves and microwaves.
5- At this temperature, the deuterium and the tritium, compacted inside the vacuum chamber by the electromagnets, merge.
VACUUM AND COLD
The structure is isolated in a cryostat, a vacuum enclosure of 16,000 meters / cube which is used to cool the structure and empty the chamber, thanks to mechanical pumps.
THE ENERGY OF FUSION
Deuterium (1) and tritium (2) merge (3) and release neutrons (4).
By slowing down, the latter release their energy in the form of heat, transformed into electricity by alternators.
