WebIn this video, we are going to explore fissile, fertile and fissionable materials! Find out how these three F's relate to the process of fission! WebMany heavy atomic nuclei are capable of fissioning, but only a fraction of these are fissile—that is, fissionable not only by fast (highly energetic) neutrons but also by slow neutrons. The continuing process whereby neutrons emitted by fissioning nuclei induce fissions in other fissile or fissionable nuclei is called a fission chain reaction.
