So far, only one reactor has successfully produced more energy than was expended, and that one is in California. But 23 countries currently have experimental reactors: USA, Canada, China, Japan, Australia, India, Iran, Kazakhstan, Pakistan, South Korea, the European Union, the Czech Republic, Spain, France, Germany, Italy, Netherlands, Portugal, Russia, Switzerland, UK, Ukraine, and Sweden.
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.
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.
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.
The expectation is that fusion reactors will provide large amounts of energy, and that they will be relatively environmentally-friendly.
Well, scientists have been researching fusion reactors for over 50 years, but nuclear fusion is much more difficult to achieve than nuclear fission, which is what current nuclear power technology is based on. There are many reasons for this, but while there have been tests and advancements in the field, scientists have yet to a) create a sustainable and stable nuclear fusion reaction and b) create a reaction that has a greater output than input.
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Well, fusion bombs are, but fusion reactors should not be (if we can build them).
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.
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?)"

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.
France has 56 nuclear reactors in operation. This makes France one of the countries with the highest reliance on nuclear energy in the world.
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.
There are currently (year 2013) 31 countries having nuclear power reactors. The rest are not having nuclear power.
Mostly power plants operating with fission reactors. Also experiments with nuclear fusion, and nuclear weapons
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
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.
