what is nuclear energy?????????
Nuclear energy is the energy released by combining of nuclei of atoms or by decay of an unstable radioactive nucleus during a nuclear reaction i.e. during fusion or a fission.
Energy released in a fission reaction:
92 U235 + 1neutron ===> 56Ba142 + 36Kr92 + 2n + Energy
Energy released in a fusion reaction:
1 H2 + 1H3 ===> 2He4 + 1neutron + Energy
