what is the fusion nuclear ?
In nuclear chemistry and in nuclear physics, nuclear fusion is a nuclear reaction in which the nuclei of two or more atoms join together to form the nucleus of a new chemical element.
Fusion has long been pursued as a potential energy source because it offers several advantages over nuclear fission. It produces virtually no long-lived radioactive waste, it doesn’t rely on rare or toxic fuel sources like uranium, and it has the potential to generate vast amounts of energy from relatively small amounts of fuel.
However, achieving controlled fusion on Earth has proven to be immensely challenging due to the extreme conditions required for the process to occur. These conditions include very high temperatures and pressures, which are necessary to overcome the natural repulsive forces between atomic nuclei. Researchers are working on various approaches to harness fusion energy, such as magnetic confinement (like in tokamaks) and inertial confinement (like in laser fusion experiments)
