Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.
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.
Fusion reactions occur in the plasma phase of matter. Plasma is a high-energy state of matter in which electrons are stripped from atoms, leading to a mixture of positively charged ions and free electrons. This highly energized state allows for the fusion of atomic nuclei, as seen in stars and in experimental fusion reactors.
Nuclear fusion typically occurs at very high temperatures in the range of millions of degrees Celsius. This is necessary to overcome the electrostatic repulsion between positively charged atomic nuclei and facilitate the fusion process.
