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 ...
Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and, depending on its point along the nuclear fuel cycle , it will have different isotopic ...
The bulk density of the fuel can be related to the thermal conductivity. Where ρ is the bulk density of the fuel and ρ td is the theoretical density of the uranium dioxide. Then the thermal conductivity of the porous phase (K f) is related to the conductivity of the perfect phase (K o, no porosity) by the following equation.
Implosion ends when the fuel reaches a supercritical density, the density at which nuclear reactions in the fuel build up an uncontainable amount of energy, which is then released in a massive explosion. To make the mockup non-nuclear, a heavy metal surrogate (such as depleted uranium or lead) stands in for the nuclear fuel, but all other ...

When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
The U.S. has announced it's sending depleted uranium anti-tank rounds to Ukraine, following Britain's lead in sending the controversial munitions to help Kyiv push through Russian lines in its ...
Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. [22] The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter).
