About 6 MeV of the fission-input energy is supplied by the simple binding of an extra neutron to the heavy nucleus via the strong force; however, in many fissionable isotopes, this amount of energy is not enough for fission. Source: Internet
A fissionable nuclide is capable of undergoing fission (even with a low probability) after capturing a high-energy neutron. Source: Internet
All fissionable and fissile isotopes undergo a small amount of spontaneous fission which releases a few free neutrons into any sample of nuclear fuel. Source: Internet
Fast reactors have the potential to produce less transuranic waste because all actinides are fissionable with fast neutrons, citation but they are more difficult to build and more expensive to operate. Source: Internet
