why is depleted uranium used in shells?
311974
Depleted uranium is a dense metal produced as a by-product of enrichment of natural uranium for nuclear fuel. It is still radioactive, but at a much lower level than the starting material. It is used in armour-piercing shells and bombs, to give them more penetrating power.

All isotopes of uranium are radioactive. Both uranium and depleted uranium, and their immediate decay products, emit alpha and beta particles and a small amount of gamma radiation. Depletion of U-235 during processing leaves DU appreciably less radioactive than naturally occurring isotopic mixtures.

Cr, Mo, Cu, Au, and Ag are the exceptions, they are the ONLY ones in which you should be doing any promoting of electrons(on your own) to have half filled shells. This is why you have 6 unpaired electrons.

Ytterbium metal has possible use in improving the grain refinement, strength, and other mechanical properties of stainless steel. One isotope is reported to have been used as a radiation source substitute for a portable X-ray machine where electricity is unavailable. Few other uses have been found.

There are a number of different ways of measuring hardness. The depleted uranium kinetic energy penetrator is a DU-titanium alloy. This report compares the hardness of different U-titanium alloys. ... Then you realize that Uranium is quite hard and harder than these steel and armor plates.

A byproduct of nuclear reactor fuel, depleted uranium was harder and denser than existing tungsten-tipped penetrators. Accelerated to extremely high speeds, this allowed a depleted-uranium (DU) round to smash through an unprecedented amount of armor.

Plutonium-239 and uranium-235 are the most common isotopes used in nuclear weapons. Each piece by itself was not enough to constitute a critical mass (the minimum amount of nuclear material needed to maintain fission)—but by colliding the pieces, critical mass was reached and a fission chain reaction occurred.

Breaking that nucleus apart—or combining two nuclei together—can release large amounts of energy. Nuclear weapons use that energy to create an explosion. Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion.

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 U-235 than natural uranium. Natural uranium contains about 0.72% U-235, while the DU used by the U.S. Department of Defense contains 0.3% U-235 or less.

In terms of the disadvantages of uranium, it can have deleterious health effects and can lead to death because of its radioactivity. Radioactive waste is also an additional issue, if it is not disposed of at a safe place and not stored properly, it can leak radiation. Such emissions can last for centuries.

Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. It does not come out of the ground ready to go into a reactor, though.

After the usable uranium is gone from the rods, the rods must be disposed of. But first, the rods are often processed with chemicals to draw out any unused uranium; this results in HLW, which is liquid waste. Then the rods are usually stored in pools of water near the reactor until a permanent location is prepared.

The RBMK used carbon as a neutron moderator, which allowed even un-enriched uranium to be used as nuclear fuel. Modern reactors use water (H2O or 2H2O) as moderator. ... This makes the RBMK design very unstable at low power levels, and prone to suddenly increasing energy production to a dangerous level.

A magazine holds shells under spring pressure in preparation for feeding into the firearm's chamber. Examples include box, tubular, drum and rotary magazines. Some are fixed to the firearm while others are removable. A cartridge "clip" has no spring and does not feed shells directly into the chamber.

Aircraft that contain depleted uranium trim weights for stabilizing wings and control surfaces (such as the Boeing 747-100) may contain between 400 and 1,500 kg of DU.

Nuclear fuel—uranium Uranium is the fuel most widely used by nuclear plants for nuclear fission. ... Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare.

Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart.
