ENERGY RELEASE FROM FISSION
The energy released will be equivalent to the difference in binding energy ( BE) between the
reactants and the products.
The energy liberation during the fission process can also be explained from the standpoint of the
conservation of mass-energy. During the fission process, there is a decrease in the mass of the
system. There must, therefore, be energy liberated equal to the energy equivalent of the mass
lost in the process. This method is more accurate than the previously illustrated method and is
used when actually calculating the energy liberated during the fission process.
Again, referring to the "typical" fission reaction.
E , the instantaneous energy, is the energy released immediately after the fission process. It
is equal to the energy equivalent of the mass lost in the fission process. It can be calculated as
