what is urenium enrichment?
446799
Enriched uranium is uranium whose uranium-235 content has been increased through the process of isotope separation. Natural uranium consists mostly of the 238U isotope, with about 0.72 % by weight as 235U, the only isotope existing in nature in any appreciable amount that is fissionable by thermal neutrons.\n\nEnriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation.\n\nDuring the Manhattan Project enriched uranium was given the codename oralloy, a shortened version of Oak Ridge alloy, after the plant where the uranium was enriched. The term oralloy is still occasionally used to refer to enriched uranium.\n\nThe 238U remaining after enrichment is known as depleted uranium (DU), and is considerably less radioactive than even natural uranium, though still extremely dense. It is useful for armor, armor penetrating weapons and other material density applications.

Preenrichment- for non fat dry milk and dry whole milk, weigh 100g of product and transfer to 1L distilled water containing 2ml of 1%aqueous brilliant green dye.Incubate at 35C for 24 +/- 2hrs. Enrichment- transfer 1ml of pre enrichd smple to 10 ml selenite cystine broth and tetrathionate broth respectively incubate at 35C for 24 +/- 2hrs.streak from enrichment media to the ff diff media: brilliant green, salmonella-shigella and bismusth sulfite incubate at 35C fo 24 +/- 2hrs.\nappearance of typical colonies:\nBGA- colorless, pink to fuchsia, translucent to opaque with surrounding medium pink to red.\nSSA- uncolored to pale pink, opaque, transparent or translucent; some produce black centered colonies.\nBSA- brown black sometimes with metallic sheen.\nsubject for further identification using  TSI agar for confirmation.streak the slant and stabb the butt. salmonella positive TSI cultures have alkaline red slants and acid (yellow) butt with or without H2S (blackening of agar) =)

Ununpentium (eka-bismuth) is the temporary name of an unconfirmed synthetic superheavy element in the periodic table that has the temporary symbol Uup and has the atomic number 115. It is made by a fusion of Calcium and Americium. It has also been known as eka-bismuth.\n\nThis is one of the more recently developed ones, only a few years old.

They are different elements. \n\nNo element of higher atomic number than uranium (92) occurs naturally because they are all radioactive and decay over time.\n\nPlutonium is a transuranic element atomic number 94 that is a by product from nuclear reactors.\n\nOnly some isotopes of uranium are fissile (U 238 is stable). Plutonium is always fissile, and so is more useful and more potent in atomic weapons.

The fact that the same element can exist on several different levels like carbon for instance being diamonds and graphite both has economic value only if we can find a way to change the allotropic state of said element.  One such example of this at present is the enriching of uranium.\n\nUranium-235 is the only naturally occurring nuclear fission fuel, but this isotope is only about 1 part in 140 of natural uranium; the balance is mostly uranium-238. Because the supply of uranium-235 is limited, the use of fast breeder reactors that convert non-fissionable uranium-238 to fissionable plutonium-239 is becoming increasingly important (see nuclear reactor). Uranium-235 can be separated from uranium-238 by a diffusion process using the gaseous hexafluoride, UF6 ; the compound of the lighter isotope diffuses faster.

A piece of uranium or plutonium is put in water, and then the water begins to boil releasing a large ammount of of energy. That energy is collected. What`s left over from this reaction is known as nuclear waste.

radioactivity is the spontaneous emission of alpha beta or gamma rays from a radioactive substance to attain stability.\nthey can be used as tracers to know the path of ne reaction\nsome of them can be used to treat cancer like co-60. and uranium is already used in nuclear reactors for generating electricity.

The highly radioactive form of uranium is a very very slightly more dense isotope than the primary isotope, thus you can purify it by any means which separates atoms based on mass.  This can be done by injecting a gaseous form of uranium into a machine which collects different fractions based on mass/charge, or crudely using an ultra-high speed centrifuge.  This info is available in a million places on the internet and taught in college physics.  The machines required to do this are extremely expensive and difficult to design, and a great deal of uranium is required-those are the limiting steps.

Yes. When we look at the Urea Biosynthesis(Ornithine Cycle),we can find Argino-succinic acid that converts into arginine & then into Ornithine. Im not sure abt arginine hydrochloride.

A centrifuge is a device that uses the principle of centrifugal force to cause the deposition (precipitation) of the more heavier component in a mixture subjected to centrifugal treatment.\n\nNatural uranium contains at most 0.7% U-235 (the fissionable isotope) and the rest is U-238.  This natural uranium is useless with respect to fission (Average nuclear warheads have enriched uranium of about 85% U-235).  So, it has to be enriched (more U-235 has to be concentrated) to levels at least about 2%, the minimum for nuclear reactors.  There are many ways of enriching uranium, but the common way is by gas centrifuging, where a centrifuge causes the precipitation of the heavier U-238 molecules to the insides of the cylinders, while the lighter u-235 molecules stay in the center.\n\nThe fuss here is that, if Iran manages to achieve enrichment levels of 5%, it can then slowly research its way to enrichment levels of 80%+, which is suitable to make nuclear warheads.\n\nCheck these links out for more information.\nhttp://en.wikipedia.org/wiki/Enriched_uranium
