Nuclear fuel
Metal uranium and its connections are used basically as nuclear fuel in nuclear reactors. Low-enriched the mix of isotopes of uranium is applied in stationary kettles of atomic power stations. A product of high degree of enrichment - in the nuclear reactors working on fast neutrons.
235U is a nuclear energy source in the nuclear weapon. This type finds the greatest application.
238U is a source of the secondary nuclear fuel - plutonium.
Geology
The basic application of uranium in Geology - definition of age of minerals and rocks for the purpose of finding-out of sequence of passing of geological processes. The geochronology is engaged in it. Essential value has also the decision of a problem on mixture and substance sources.
Additional spheres of application of uranium
Uranium-235 carbide in an alloy with columbium carbide and zirconium carbide is applied as fuel to nuclear jets (a working body - hydrogen + hexane).
The small additive of uranium attaches beautiful yellow-green fluorescence to a glass (uranium glass).
Uranate of sodium Na2U2O7 was used as a yellow pigment in painting.
Uranium connections were applied as an artist's colour on porcelain and to ceramic glazes and enamels (colour in colours: yellow, brown, green and black, depending on oxidation state).
In the XX-th century beginning uranilnitrat it was widely applied to strengthening of negatives and colouring (toning) of positives (photographic replicas) in brown colour.
Alloys of iron and the impoverished uranium (uranium-238) are applied as powerful magnetostrictive materials.
Some connections of uranium are photosensitive.
The impoverished uranium
Such uranium is used for radiating protection and ballast weight in space applications, such as steering surfaces of flying machines.
For these purposes in plane "Boing-747" 1500 kg of the impoverished uranium contain.
The material is applied in high-speed rotors of gyroscopes, the big flywheels, as a ballast in space landers and racing yachts, at drilling of oil wells.
Cores of armour-piercing shells
The most known application of the impoverished uranium - as cores for armour-piercing shells.
For the first time uranium as the core for shells has been applied in the Third Reich.
The impoverished uranium is used in the modern tank reservation (in the fighting tank of USA[ru] M-1 «Abrams») which costs on arms of army and marines of the USA, Egypt, Saudi Arabia, Kuwait and Australia. The tank is named in honour of general Krejtona Abramsa.
