NUCLEAR FUSION

TOPIC: Science & Tech

Context- Scientists have been making efforts to build a fusion nuclear reactor for several decades.

Concept-

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.
Energy released in most nuclear reactions is much larger than in chemical reactions, because the binding energy that holds a nucleus together is greater than the energy that holds electrons to a nucleus.
Nuclear Fusion is considered by some scientists to be a potential energy of the future, particularly because it produces little waste and no greenhouse gases.
