First, Iran must halt all enrichment of uranium to 20 purity (a level required for research reactors, but only a short step away, in practical terms, from weapons grade uranium).

Carbides of uranium include uranium monocarbide (UC), uranium dicarbide (), and diuranium tricarbide ().

The most important oxidation states of uranium are uranium(IV) and uranium(VI), and their two corresponding oxides are, respectively, uranium dioxide () and uranium trioxide ().

Iraqi blogger Layla Anwar writes a detailed post about the contamination in Falluja resulting from depleted uranium and white phosphorous used in the war on Iraq and the cover up preventing thorough research.

Now if you consider the fact that nuclear weapons proliferation is associated with nuclear energy proliferation, because we know for example, India and Pakistan developed nuclear weapons secretly by enriching uranium in nuclear energy facilities.

As Iran s uranium enrichment and other weapons development activities continue unabated, the US needs to make a break with the old rules of engagement.

It was believed that the Japanese nuclear weapons program was not far advanced because Japan had little access to uranium ore, but it was initially feared that Germany was very close to developing its own weapons.

One method of preparing uranium tetrachloride () is to directly combine chlorine with either uranium metal or uranium hydride.

Isotope separation Natural uranium consists of 99.3 uranium 238 and 0.7 uranium 235, but only the latter is fissile.

Armaments Tungsten, usually alloyed with nickel and iron or cobalt to form heavy alloys, is used in kinetic energy penetrators as an alternative to depleted uranium, in applications where uranium's radioactivity is problematic even in depleted form, or where uranium's additional pyrophoric properties are not required (for example, in ordinary small arms bullets designed to penetrate body armor).

You drive. You take your depleted battery out.

Breeding As opposed to current light water reactors which use uranium 235 (0.7 of all natural uranium), fast breeder reactors use uranium 238 (99.3 of all natural uranium).

Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (), and diuranium trinitride ().

This continues until all of the cards are depleted.

If and when the supply is depleted, paralysis occurs.

In 1941 he began working with uranium hexafluoride, the only known gaseous compound of uranium, and was able to separate uranium 235.

The high uranium content makes carnotite an important uranium ore and also radioactive.

The NDRC Committee on Uranium became the S 1 Uranium Committee of the OSRD the word uranium was soon dropped for security reasons.

extractive metallurgy of uranium.

This was then heated to form uranium trioxide, which was reduced to highly pure uranium dioxide.

Highly enriched uranium (HEU) Highly enriched uranium (HEU) has a 20 or higher concentration of 235U.

Niche uses Applications requiring its high density include weights, counterweights, ballast keels for yachts, tail ballast for commercial aircraft, and as ballast in race cars for NASCAR and Formula One depleted uranium is also used for these purposes, due to similarly high density.

Democratic weapons or weapons of democracy?

Uranium dioxide is the form in which uranium is most commonly used as a nuclear reactor fuel.

Work was proceeding on three different techniques for isotope separation to separate uranium 235 from uranium 238.

Grades Slightly enriched uranium (SEU) Slightly enriched uranium (SEU) has a 235U concentration of 0.9 to 2 .

There's great concern that basking sharks are depleted all throughout the world.

Fishermen knew about these things they caught them, and they depleted them.

Helium is also depleted, to about 80 of the Sun's helium composition.

In extreme cases, an individual's personality may end up becoming critically depleted.

And then we get to uranium.

Actinium 227 occurs in uranium ore.

This creates a uranium concentrated precipitate.

Pitchblende, after removal of the radioactive elements uranium and thorium, was more radioactive than the uranium and thorium combined.

Reprocessed uranium (RepU) Reprocessed uranium (RepU) is a product of nuclear fuel cycles involving nuclear reprocessing of spent fuel.

For example, ν 2.5 for uranium 235.

Aggregate U 235 production About of uranium enriched to 89 uranium 235 was delivered to Los Alamos by July 1945.

Because the sloth bears in the wild were obviously getting depleted because of this.

The reduction of by hydrogen produces uranium trichloride () while the higher chlorides of uranium are prepared by reaction with additional chlorine.

thermonuclear weapons).

In 1983, the country admitted having the capability of producing weapon grade uranium, a major step needed to assemble nuclear weapons since then, however, Argentina has pledged to use nuclear power only for peaceful purposes.

The uranium was seized in a sting operation.

All uranium chlorides react with water and air.

They are classified as weapons of mass destruction, though they are separate from biological weapons (diseases), nuclear weapons, and radiological weapons (which use radioactive decay of elements).

A relatively simple gun type fission weapon was made using uranium 235, an isotope that makes up only 0.7 percent of natural uranium.
