  • The energy harnessed in nuclei is released in nuclear reactions. Fission is the splitting of a heavy nucleus into lighter nuclei and fusion is the combining of nuclei to form a bigger and heavier nucleus. The consequence of fission or fusion is the absorption or release of energy.

    • Contrasting Nuclear Fission and Nuclear Fusion
      Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

    • Fission Chain Reaction
      A chain reaction is a series of reactions that are triggered by an initial reaction. An unstable product from the first reaction is used as a reactant in a second reaction, and so on until the system reaches a stable state. It usually follows a pattern of initiation (initial spark), propagation (continuation of the process) and termination (reaching a stable state).
