It is part of the Interstate 80 family, and connects Interstate 580 with Interstate 880. U-238 is the non-fissile isotope of uranium that is the heaviest isotope of any

Uranium-238 and Uranium-235 are the parent isotopes of decay chains that can be used to provide a chronology back to ∼500 ky. In an old system (≫500 ky) a radioactive secular equilibrium is established between the parent 238 U or 235 U and their daughter radioisotopes. Uranium is a radioactive element with atomic symbol U, atomic number 92, and atomic weight 238.

Uranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239. 238 U cannot support a chain reaction because

Massöverskottet hos 238U är 47307 keV.
