In nature, the stars. Man made reactors have not been successful yet, but the most promising are the tokamak types, which are toroidal chambers where a plasma containing the fuel in gaseous form is heated to a very high temperature to produce fusion. You can read more in Wikipedia
What else can I help you with?
Do fusion powers nuclear reactors?
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Are nuclear fusion dangerus?
Well, fusion bombs are, but fusion reactors should not be (if we can build them).
What are the three main advantages of a fusion reactor compared to a fission reactor?
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.
How are they different from regular nuclear reactors?
Please elaborate on "they" as no comparison can be given otherwise. Do you mean?: "How is nuclear fusion different from regular nuclear reactors (nuclear fission?)"
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.
Why is the development of nuclear fusion reactors desirable?
The development of nuclear fusion reactors is desirable because they offer a potentially limitless and clean energy source with minimal greenhouse gas emissions. Fusion reactors use isotopes of hydrogen as fuel and produce no long-lived radioactive waste, offering a safer alternative to current nuclear fission reactors. Additionally, fusion fuel sources are abundant and widely available, making fusion a promising solution for meeting global energy demands sustainably.
What can be found on the moon that can be used for nuclear reactors?
Helium-3 can be found on the moon and has the potential to be used in nuclear fusion reactors. It is an ideal fuel source due to its abundance on the moon and its efficiency in producing energy through fusion reactions.
What does energy includes?
Mostly power plants operating with fission reactors. Also experiments with nuclear fusion, and nuclear weapons
Why have no fusion reactors been built yet?
Fusion reactors have not been built yet because it is challenging to create and sustain the extreme conditions required for nuclear fusion to occur, such as high temperatures and pressures. Scientists are still working on developing the technology to make fusion reactors a viable and practical energy source.
Why would nuclear power plants using fusion be potentially better?
Nuclear fusion combines hydrogen atoms into helium atoms. Hydrogen is available from water and helium is an inert gas. When fusion reactors become technologically feasible, we will greatly reduce consumption of limited fossil fuels and production of greenhouse gases. Fusion reactors will not produce high level nuclear waste.
Does nuclear fusion create radioactive waste?
Nuclear fusion does not create long-lasting radioactive waste like nuclear fission does. However, some materials used in fusion reactors may become radioactive and need to be handled carefully.
Where has nuclear fusion been used?
Nuclear fusion has been primarily used in research facilities and laboratories to study its potential for generating energy. It has not yet been harnessed for practical energy production on a commercial scale, although there are ongoing efforts to develop fusion reactors for this purpose.
