  2. Uranium-235 - Wikipedia

    en.wikipedia.org/wiki/Uranium-235

    Uranium-235 (235 U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years.

  3. Fission products (by element) - Wikipedia

    en.wikipedia.org/wiki/Fission_products_(by_element)

    Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.

  4. Uranium - Wikipedia

    en.wikipedia.org/wiki/Uranium

    Uranium-235 was the first isotope that was found to be fissile. Other naturally occurring isotopes are fissionable, but not fissile. [citation needed] On bombardment with slow neutrons, uranium-235 most of the time splits into two smaller nuclei, releasing nuclear binding energy and more neutrons.

  7. Isotopes of uranium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_uranium

    Uranium-235 makes up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction. It is the only fissile isotope that is a primordial nuclide or found in significant quantity in nature. Uranium-235 has a half-life of 703.8 million years.

    Uranium is the only naturally occurring element in non-trace amounts of a fissile isotope, uranium-235, which makes it widely used in nuclear power plants and nuclear weapons. However, because of the low abundance of uranium-235 in natural uranium (which is, overwhelmingly uranium-238), uranium needs to undergo enrichment so that enough uranium ...
