DU mesh armor is used on most modern main battle tanks such as the US M1A2 Abrams, British Challenger 2, and German Leopard 2 (A4-A7). DU has been rumored to have been recently used in new armor piercing rounds, but they are largely unconfirmed.

What does the uranium enrichment program mean?
The concentration of the isotope uranium 235 in natural uranium is approx. 0,7 %. Enrichment is the process which increase this concentration. The necessary concentration for military use - atomic bombs is more than 90 %. Also many nuclear reactors work with enriched uranium (but with only 3-5 % uranium 235).
Is uranium on the sun?
no. the sun uses fussion, not fission. fussion requires two hydrogens that "fuse" to make a helium, which gives off a lot more energy then fission. It does not require uranium.
How much does it cost to make a nuclear weapon?
A absolutely gigantic amount! First you need to mine hundreds of tons of uranium ore, then you need to purify it, by conversion to uranium hexaflouride. I will not go into the detail of this process, but the resulting uranium hexaflouride is VERY toxic. THen the uranium hexaflouride needs to go through one of two processes: gaseous diffusion of ultra-high speed centrifuging. The first dydtem is the one used for bulk U-235 (the resulting weapons grade uranium) during the Manhattan project. It uses baffles and filters (made of things like tungsten-zirconium alloys) to separate the U-238 (the depleted uranium that makes up 95% of the uranium ore) form the U-235. The second process is centrifuging, where the uranium hexafluoride is spun at 500 MPH until the heavier U-238 is separated. The uranium is the only really expensive part in a gun-type weapon, but the big weapons,fusion bombs use plutonium which production is to complicated to go over here.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
How is uranium used in bombs?
The following is typical, but there are a number of variations, mostly minor: Uranium is first found by exploration. It is then mined. The ore is milled to produce small pieces, which are then chemically leached to produce an uranate called yellocake. The yellowcake is reacted to produce uranium hexafluoride , which is then run through centrifuges to separate a heavier fraction from a lighter fraction. The lighter fraction is the enriched material used for power plants, the heavier is referred to as depleted. The enriched uranium is chemically converted to another oxide, uranium dioxide, and this is converted into the form of fuel used in plants, commonly by pressing and sintering. The fuel is encased in cladding of special steels or zircaloy, and then is ready to be put into the reactor. There is a link to a more detailed answer below.
What is a common use of uranium?
Two uses of uranium are very important:- nuclear fuel for nuclear reactors- explosive for nuclear weapons
What are two other uses for nucear material?
Energy production, radiation sources for test eequipment (x-rays, beta particles, etc), art, glow-in-the-dark applications, non-nuclear munitions (look up depleted uranium).

When will uranium supplies get depleted?
If mined at current rates a few centuries. Breeder reactors will extend this to a few millennia. If unmined, the fissile 235U fraction would no longer be economical to enrich in two to three billion years.
What is uranium mass when it splits?
Splitted uranium is not uranium, but other two lighter elements.
What type of plant uses uranium?
Nuclear power plants all use uranium to some degree. There are only two radioactive elements found on Earth in sufficient concentrations to mine that can be used for nuclear power. These are uranium and thorium. Thorium cycle power plants of various types are being researched and developed, but none are currently producing power for an electric grid. Uranium-233 is part of the thorium cycle, so uranium will be present in thorium cycle reactors, and its energy is used there. There are a number of nuclear plant designs that use plutonium, though they are not common. None is producing power in the United States. And even these also use uranium. In fact, the plutonium is produced from uranium.
How can the sun's energy source be used directly?
Two common uses are to heat water; and to generate electricity with photovoltaic cells.Two common uses are to heat water; and to generate electricity with photovoltaic cells.Two common uses are to heat water; and to generate electricity with photovoltaic cells.Two common uses are to heat water; and to generate electricity with photovoltaic cells.

What are the two most common isotopes used as nuclear fuels?
in reactors: yellowcake, a uranium oxide; after that probably metallic uraniumin stars: ordinary hydrogen; after that helium
