Uranium has three different naturally occurring isotopes: U234, U235 and U238. The most common isotope is U238, which accounts for over 99% of natural uranium. The important nuclear energy carrier U235 used in power generation makes up for around 0.7% of all uranium, while U234 occurs onl...

Depleted uranium is an important defense strategy is also important material, the nuclear power fuel. Uranium mining companies do a good job of work safety, and ensuring stable supply of uranium resources, and uranium mining system good and fast, secure development has become an imperative. ...
Describe how nuclear fusion generate more stable nuclei. Is uranium-235 more likely to undergo nuclear fusion or nuclear fission? Explain. Nuclear fission and nuclear fusion are two distinctly different processes. Describe each process and give examples. Examples shou...
GessenhaldeStable isotopes, 2Hwater, 18Owater as well as 18Osulphate and 34Ssulphate, were used to study the flow system of shallow groundwater and soil water at the base area of a former leaching heap at the uranium mining area of Ronneburg, Germany. The flow paths and water-retention ...
