1 10.1 Nuclear energy Nuclear Fission Nuclear Fusion Curve of the Binding Energy/nucleon fusion fission Energy can be released by nuclear reactions of Fusion and Fission 1MeV/nucleon Natural radioactivity Many elements found in nature are unstable and decay emitting radioactivity. These include Uranium, 238 U , Radon 224 Ra and Potassium 40 K. Carbon 14 C, The half lives of natural radio-isotopes are long. Not useful as sources for power. Low Power output. Nuclear Power Nuclear power requires induced nuclear fission. Nuclear fission can be induced by neutrons in a chain reaction. Nuclear fusion can be induced by collisions at high temperature.
