magnetic confinement, inertial confinement

∙ 10y ago
You are most likely referring to a magnetic confinement fusion device, such as a tokamak or a stellarator. These devices use powerful magnetic fields to confine and control high-temperature plasma, enabling the conditions necessary for a controlled fusion reaction to occur. Scientists and researchers study and investigate these devices in order to develop a viable and sustainable method of achieving nuclear fusion as a clean and abundant source of energy.

On Earth what's being investigated to contain fusion reactions?
magnetic confinement inertial confinement
Which of the following are being investigated to contain fusion reactions on earth?
magnetic confinement inertial confinement
Which fusion reaction could possibly result in fusion being a viable source of energy dt reaction dd reaction or protium reaction?
The first one to become successful in man made fusion will certainly be DT, but DD would be better if it could be made to work, as it would avoid the need to make tritium to feed as part of the fuel, and there are unlimited supplies of deuterium in the earth's waters. By "protium" I suppose you mean the proton-proton reaction as in the sun, this is impossible in man made fusion on earth, as it requires a huge volume and very high pressure as exists at the centre of the sun.
Do fusion reactions provide nuclear power?
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
What are the by-products of nuclear fusion?
In general, nuclear fusion produces a new atom (or, in some cases, two atoms), a change in the amount of heat present and possibly some other emission. The specific products of nuclear fusion depend on what is being fused. The fusion of 2H + 2H produces 3H + a proton + 4.02 MeV The fusion of 2H + 3H produces 4He + a neutron + 17.6 MeV The fusion of 6Li + 2H can produce 4He + 4He + 22.4 MeV In the cases where fusion produces atoms heavier than iron, the reaction is endothermic, consuming heat rather than producing it.

Is fusion an endothermic reaction?
It depends on what is being fused. Fusion usually takes place with elements lighter than iron, mostly hydrogen. in those cases it is exothermic. Fusin elements heavier than iron is endothermic.
What new alloys are being investigated?
metallic alloy
It takes an extremely high temperature for nuclear to occur inside the sun?
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.

yes

Why do they not have not any fusion reactors?
We are working on building controlled fusion reactors but, so far, have been unable to overcome the technological problems in doing so. There have been some minor successes, but only on a microscopic scale. One of the hard parts is maintaining the extremely high pressures and temperatures that are required to sustain a fusion reaction, in combination with being able to contain that reaction. The plasma state needed for the fusion reaction cannot be contained by anything mechanical, as it is too hot. In the Sun, this works because of the extreme mass present, causing enough gravity to sustain the pressure needed. On Earth, we can not use anywhere close to the Sun's mass, so we go with magnetic fields. Problem is, that in order to produce a magnetic field strong enough to hold the plasma, you often need super-conducting magnets, which require super-cold temperatures - yet that has to be sustained in close proximity to the ultra high temperature of the fusion reaction. So far, the only successful fusion reactors we have are uncontrolled, i.e. Hydrogen Bombs. That would, of course, not do for a power reactor. It is interesting to note that the amount of energy required to initiate a fusion reaction is enormous - so enormous that Hydrogen Bombs actually use Atomic (fission) Bombs to set them off. That's part of the problem with controlled fusion reactions - the amount of energy required to initiate them.

What is interpreting data?
It is to decide what the data indicates about the hypothesis or problem being investigated.
