Fission is a nuclear reaction where a heavy atom is split up into lighter elements, thereby producing energy. Fission is commonly used in nuclear power plants, but someday they will use fusion. Fusion is a nuclear reaction where very light elements are fused together under enormous heat and pressure into heavier elements, thereby producing energy. The Sun and all the stars are fusion reactors. Thermonuclear bombs (H-bombs) use fission (an A-bomb) to produce the heat needed for fusion.

Nuclear fission is the splitting of heavy nuclei (as U-235) when bombarded by neutrons. The nuclear fusion is the combination of light nuclei into heavier nuclei. Both the nuclear fission and nuclear fusion result in loss of mass (or mass defect) that transforms into energy according to formula E = mc2 (c is light velocity).

Nuclear physics is the field of physics?

Nuclear Physics is a field of physics, yes. It involves interactions between atomic nuclei. Nuclear fission, nuclear fusion, nuclear decay (though in some ways that is more particle physics).


What type of power does nuclear fission have?

Fusion power is the power generated by the nuclear fusion processes. Fusion power is a primary area of researc in plasma physics. For example, the sun is a natural fusion reactor.
