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 has an even higher concentration of 238 U, and even low-enriched uranium (LEU) is still mostly 238 U. Reprocessed uranium is also mainly 238 U, with about as much uranium-235 as natural uranium, a comparable proportion of uranium-236, and much smaller amounts of other isotopes of uranium such as uranium-234, uranium-233, and ...
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’
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.
Because of this, a light-water reactor will require that the 235 U isotope be concentrated in its uranium fuel, as enriched uranium, generally between 3% and 5% 235 U by weight (the by-product from this process enrichment process is known as depleted uranium, and so consisting mainly of 238 U, chemically pure).
ICBUW campaigns for a ban on the use, transport, manufacture, sale, and export of all conventional weapon systems containing uranium (usually called depleted uranium weapons). It also seeks health monitoring and compensation for communities affected by the use of uranium weapons and the environmental remediation of such sites. [2]
