Difference Between Fissile and Fertile Isotopes

WebIt is the only naturally-occurring fissile nuclear fuel. Fissionable. There is a slightly larger category of materials, called fissionable, which includes all isotopes that can undergo fission. Some fissionable isotopes, such as uranium-238, only fission when the neutron striking is of high energy. All fissile materials are also fissionable ... WebNuclear Physics. Define 'fissionable nuclide' and name two. [5 points] A fissionable nuclide can be caused to split apart (fission) by a neutron.
