Depleted uranium (DU), also referred to in the past as Q-metal, depletalloy, or D-38, is uranium with a lower content of the fissile isotope 235 U than natural uranium. [2] The less radioactive and non-fissile 238 U is the main component of depleted uranium.
Depleted uranium – uranium material with a reduced percentage of the fissile isotope U-235 following processing in the form of depleted uranium hexafluoride (DUF6) – remains on site for continuing processing. The DUF6 Conversion facilities are located at both the Portsmouth Gaseous Diffusion Plant and the Paducah Gaseous Diffusion Plant.
The concept of depleted and enriched uranium emerged nearly 150 years after the discovery of uranium by Martin Klaproth in 1789. In 1938, two German physicists Otto Hahn and Fritz Strassmann had made the discovery of the fission of the atomic nucleus of the 235 U isotope, which was theoretically substantiated by Lise Meitner, Otto Robert Frisch and in parallel with them Gottfried von Droste ...
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
Mixed oxide, or MOX fuel, is a blend of plutonium and natural or depleted uranium which behaves similarly (though not identically) to the enriched uranium feed for which most nuclear reactors were designed. MOX fuel is an alternative to low enriched uranium (LEU) fuel used in the light water reactors which predominate nuclear power generation.
Chain reactions are accomplished by concentrating, or enriching, the fuel, increasing the amount of 235 U to produce enriched uranium, [14] while the leftover, now mostly 238 U, is a waste product known as depleted uranium. 235 U will sustain a chain reaction if enriched to about 20% of the fuel mass.

Reuters was first to report last week that the rounds, which could help destroy Russian tanks, would form part of a new military aid package for Ukraine, which Russian forces invaded in February 2022.
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.
