Detailed explanation-1: -6.6 MeV is released on account of nuetron being absorbed or bound to U-234 nucleus. Thus, Binding Energy of Last Neutron is 6.6 MeV. Energy necessary to be supplied to induce fission is called Critical Energy for Fission.
Detailed explanation-2: -Nuclear binding energy is the energy required to keep the protons and neutrons of a nucleus intact, and the energy that is released during a nuclear fission or fusion is nuclear power.
Detailed explanation-3: -When any unstable nuclei get bombarded with neutrons then it undergoes nuclear fission reaction. The value of atomic number as well as atomic mass remains conserved on the reactants as well as the product side. Therefore, 1 neutron is needed to initiate the given nuclear fission reaction.
Detailed explanation-4: -Hence binding energy per nucleon increases in the fission process.
Detailed explanation-5: -In fission, an unstable nucleus is converted into more stable nuclei with a smaller total mass. This difference in mass, the mass defect, is the binding energy that is released. In fusion, the mass of the nucleus that is created is slightly less than the total mass of the original nuclei.
