Enriched uranium is still usually mainly 238U, but it has a higher percentage of 235U than the natural abundance. Depleted uranium is exactly the opposite: it's got a LOWER than normal amount of 235U.

Enriched uranium: uranium with more than 0.7 % uranium 235. Uranium 238 is not enriched uranium.


Uranium is enriched in the isotope uranium-235, producing uranium-238 as waste.


Uranium-235 and uranium-238 has 92 protons and 92 electrons; but uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.


Uranium-235 in combination with Uranium-238, enriched from natural levels of about 0.7% U-235 to about 5% U-235. There are other configurations, but this is the most common.


Enriched uranium is an uranium with more than 0,7 % uranium 235.


- Uranium-235 has 143 neutrons. - Uranium-238 has 146 neutrons. - The atomic mass of uranium-238 is greater.


Uranium 235 has 92 neutrons and uranium 238 has 95 neutrons.


U-235 and U-238 are natural radioactive isotopes.


Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.


U-235 is the enriched form of U-238 which is used in fission reactors as the fuel rods.


Uranium 235 has 143 neutrons and uranium 238 has 146 neutrons.


Enriched uranium is uranium that has had its U-235 isotope content elevated above what it would be when we refine natural uranium after recovering the metal from ore.We know that U-235 is the desired fissionable isotope of uranium, but it is the isotope U-238 that is present in over 99% of all the naturally occurring uranium we mine and recover. We have to put the uranium through a process to separate the U-235 from the U-238. As these two isotopes are chemically identical, it takes a mechanical process to separate them. After running the uranium through a process designed to take advantage of the difference in the mass of the two atoms, the industry will recover uranium with a very high percentage of the U-235 isotope, and this is called enriched uranium.If uranium is enriched to a point where there is up to about 20% U-235, it is low-enriched uranium. Above that 20% mark we see highly enriched uranium. Above about 85%, we call the product weapons-grade uranium. A link can be found below for more information.


U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.





The uranium isotope that is actually useful (whether for a reactor, or for an atomic bomb) is U-235. Natural uranium contains only about 0.7% of this; the remainder is mainly U-238. Therefore, it must be enriched, to have a greater percentage of U-235.



Uranium 235 halflife: 7,038.108 years Uranium 238 halflife: 4,468.109 years


Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.


Uranium can be reused after the separation from the other products of the nuclear fission: uranium enriched with the isotope 235 as fissile material and depleted uranium (mainly the isotpoe 238) as fertile material.


Uranium-238 don't suport a nuclear chain reaction; reasons belong to nuclear physics. Uranium-235 - yes !


Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
