Nuclear Fusion

Definition - What does Nuclear Fusion mean?

Nuclear fusion is a nuclear reaction triggered by the collision of two or more atomic nuclei. Some of the matter that makes up these nuclei is converted into energy in the form of photons. Nuclear fusion as a means of generating energy has not yet been achieved, but several facilities believe that they are close to a solution.

Safeopedia explains Nuclear Fusion

The sun is an example of a nuclear fusion reaction. Physicists believe that nuclear fusion, if it can be achieved in such a way that the energy exerted to achieve the reaction is less than the energy produced, could become a clean, safe means of generating sufficient energy to satisfy the world’s energy demands. Although there are not yet any working fusion reactors generating power, physicists at several facilities including the National Ignition Facility in Livermore, California believe that they are close to achieving this goal.
