Physics of Uranium and Nuclear Energy
WebFusion is a process in which two nuclei combine to form a nucleus of larger mass number. Fusion is the main nuclear process that occurs in the Sun and other stars. The … WebNuclei that can be fissioned by higher energy neutrons are fissionable, but may not be fissile, in that they cannot be fissioned by low energy or thermal neutrons, which have typically less than 1 million electron volts (MeV) of energy. Fissionable materials need high energy or fast neutrons to undergo fission reactions. WebAug 3, 2024 · Fissionable materials include also those (such as uranium-238) that can be fissioned only with high-energy neutrons. ... U- 238 is a fissionable isotope, meaning that it can undergo nuclear fission, but the neutrons fired at it would need much more energy in order for fission to take place. because of the large amount of energy needed, U- 238 ... swayness
