Many contemporary uses of uranium exploit its unique nuclear properties. Uranium is used in nuclear power plants and nuclear weapons because it is the only naturally occurring element with a fissile isotope – uranium-235 – present in non-trace amounts.
Separated plutonium and enriched uranium could be used for nuclear weapons, which – even with the current centralized control (e.g. state-level) and level of prevalence – are considered to be a difficult and substantial global risk for substantial future impacts on human health, lives, civilization and the environment.

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.
According to Michigan State University, the use of uranium was deregulated in 1958, and production of uranium glass picked up again—except this time, only depleted uranium was used. This is when ...
Depleted uranium, which has about the same density as natural uranium, is used when this high density is desirable but the higher radioactivity of natural uranium is not. Civilian uses include counterweights in aircraft, radiation shielding in medical radiation therapy, research and industrial radiography equipment, and containers for ...
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
Russia supplied about 24% of the uranium used by reactors in the U.S. in 2022, and was its top foreign supplier. But Kathryn Huff, the DOE's assistant secretary for nuclear, who steps down on ...
Uranium-235, the fissile isotope of uranium used in nuclear reactors, makes up about 0.7% of uranium from ore. It is the only naturally occurring isotope capable of directly generating nuclear power. While uranium-235 can be "bred" from 234 U, a natural decay product of 238
