Nuclear fusion is used in some nuclear power plants that can handle the heat and radiation without suffering a meltdown. You should check out nuclear fission in power plants first.
Nuclear fusion will be used as a power source when we decide that we have actually killed the planet. It is what the sun does 24/7 and we are just trying to do it in a controlled environment
yes. this is because nuclear power plants use nuclear fusion
Fission
Nuclear energy as we use it now is from nuclear fission. Nuclear fusion is the joining up of nuclei rather than the splitting (fission), but it is not yet available on Earth.
Because no one has been able to produce a continuous fusion reaction so far.
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.
Uranium has stored energy (potential energy), more specifically, nuclear energy.
yes. this is because nuclear power plants use nuclear fusion
Nuclear fusion is not used for any purpose at present, it is still in the experimental phase
Nuclear fusion rocket technology is too expensive to use as a means for power production.
We don't yet know how to use fusion in a power plant. All nuclear power plants use fission only. Fusion is much harder, but will be better if we can figure it out.
Because it is a fission process, not fusion
Fission
Nuclear physics is relevant to the average person in the way it affects energy use of humans. These advances include electricity, fission, nuclear power pants, and perhaps cold fusion in the future.
There is very little similarity between present day power plants which use nuclear fission, and any possible nuclear fusion plant of the future
Nuclear fusion is unsure now at industrial scale.
Helium-3 is used in experiments for nuclear fusion, neutron detection, cryogeny installations and RMN for medical use.
Because it is a fission process, not fusion
