We have as yet been unable to sustain a stable fusion reaction long enough for this to work.

It is in fact not used at all, and this is because it has not been made to work yet. Research continues but it won't happen for many years yet.

It has turned out to be fairly difficult to combine a high temperature (about 100 million kelvin) with a high pressure, and maintain these conditions, even for a few seconds.

Can you use the energy produced by nuclear fusion for something?

Sure, you can get a tan from it, since the Sun is a big fusion power reactor. In the near future we will be able to build fusion reactors here on Earth. Google "ITER" to see how it's going. In the meantime I suppose you can say the fusion power is actually solar energy.


What date did the first fusion generator operate?

The first work on nuclear fusion was performed in 1933 by Ernest Rutherford. The first nuclear fusion "reactor" was built in 1947 by teams in the UK and USSR. To this day no nuclear fusion "reactor" has been able to produce more energy than had to be put into it to get the reaction started, despite many different experiments on many different designs.


What are the main reasons why fusion reactions are not used in nuclear reactors?

No design of a fusion reactor has yet been able to reach what is called breakeven: the ability to make as much energy as it takes to operate the reactor. Until a prototype fusion reactor can make enough energy to operate itself, it is useless to even consider the uses of fusion reactions in possible power plants of the future.The temperature of a fusion reaction is not only high enough to melt any matter it touches but to vaporize that matter into a plasma! Therefore the reacting materials and their products must be confined in the reactor using forcefields not matter. We do not yet know how to make strong enough forcefields reliably.


When did humans begin to pollute?

As soon as we were able to build fire.


Why havent humans been able to build a fusion reactor?

We have not been able to build a stable, controlled fusion reactor because of the problem of confinement. In order to sustain a fusion reaction, we need to hold the fuel together. That requires tremendous energy in order to overcome the electromagnetic force that would otherwise cause the various nuclei to repel each other, and in order for the residual binding energy (nuclear force) to initiate fusion.In the Sun, that is easy. Gravity does it. Problem is, that a reactor large enough to use gravity would be larger than the Earth and would destroy the Earth.Its not a "problem" with an uncontrolled fusion bomb. We have that technology perfected. The "problem" is doing so in a controlled fashion, and we have not been able to do so for more than about 500 milliseconds.Other methods are being explored, such as inertial confinement and magnetic confinement. Magnetic confinement is the basis for the Tokamak, which is the foundation of the ITER project in France. There are substantial technical issues involved, and we do not expect first plasma production until 2019, with end of project slated for 2038. Even then, we are only talking about 500MW thermal output for 1000 seconds, based on 50MW of input power, with no production of electricity - all at a cost of around 100 billion euros.


What happens in a fusion reactor if the plasma touched the sides of the container?

The energy used to allow nuclear fusion to happen would be transferred to the surroundings through the metal container because it is a conductor therefore the plasma would cool down and the reaction wouldn't be able to carry on.


Is containment the cure the to nuclear radiation in chernobyl?

yes if we build a dome around the nuclear reactor we may be able to contain the radiation but we will not be able to clean up the radiation left over already.


How is nuclear fusion fuels is used?

It's used in stars to generate light and heat. Even though we've been trying for decades, humans haven't yet been able to sustain fusion.


Why cant you use fusion to produce energy?

Scientists and engineers have not yet been able to build an apparatus to make it work-but they are still trying


Why are instects no longer able to resiste pesticides?

they can build up in animals and humans and cause more damage


Can Charmeleon or Charizard learn fusion flare?

Neither are able to learn Fusion Flare.


What are the functions of the deuterium and tritium atoms in nuclear reactors?

All current nuclear reactors are fission reactors, tritium has no function in a fission reactor, in standard water moderated reactors deuterium also has no function, in heavy water moderated reactors deuterium is the moderator. If we are ever able to make a fusion reactor, deuterium/tritium mix will be used as fuel.
