WebUranium. Uranium is a trace element that occurs naturally in the earth's crust. All of the isotopes of uranium are unstable and are radioactive. The most abundant isotopes are 238 U and 235 U. The percentage abundance of 238 U is 99.25 percent and the abundance of 235 U is 0.75 percent. WebUranium [ edit] 96% of the mass is the remaining uranium: most of the original 238 U and a little 235 U. Usually 235 U would be less than 0.8% of the mass along with 0.4% 236 U. Reprocessed uranium will contain 236 U, which is not found in nature; this is one isotope that can be used as a fingerprint for spent reactor fuel.
