Mostly in test reactors, though some operational reactors (though only a small number) are in service. Also, if you have ever heard of an H-bomb, or a hydrogen bomb, that is nuclear fusion.

Which one of these two process is still used today Nuclear Fission or Fusion?

Fission. Fusion has never been used on Earth, except for nuclear weapon tests.


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

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.


Does fusion powers many of your nuclear power plants?

Nuclear fusion is used only in experimental installations.


Where does nuclear fusion occur in a nuclear plant?

Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.


What is the difference between hot nuclear fusion and cold nuclear fusion?

"Hot" nuclear fusion (this is not the term normally used) is exactly what the name implies, the materials are heated, which provides them with enough energy to overcome the normal repulsion of protons. Cold nuclear fusion requires no heating and has not yet been proved, although dozens of Physicists and Electro-Chemists have claimed to have created cold fusion. Cold Fusion relies on other forces, such as pressure, to overcome the electrostatic force of repulsion.

What are the Application of nuclear fusion?

Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system. There is a link below to an article on nuclear fusion.

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.


What energy would be used in a nuclear reaction in a star?
