Maybe you are referring to uranium enrichment?\n\nUranium found in nature consists largely of two isotopes, U-235 and U-238. The production of energy in nuclear reactors is from the `fission' or splitting of the U-235 atoms, a process which releases energy in the form of heat. U-235 is the main fissile isotope of uranium.\n\nNatural uranium contains 0.7% of the U-235 isotope. The remaining 99.3% is mostly the U-238 isotope which does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium).\n\nUranium-235 and U-238 are chemically identical, but differ in their physical properties, particularly their mass. The nucleus of the U-235 atom contains 92 protons and 143 neutrons, giving an atomic mass of 235 units. The U-238 nucleus also has 92 protons but has 146 neutrons - three more than U-235, and therefore has a mass of 238 units.\n\nThe difference in mass between U-235 and U-238 allows the isotopes to be separated and makes it possible to increase or "enrich" the percentage of U-235. All present enrichment processes, directly or indirectly, make use of this small mass difference. \n\nA number of enrichment processes have been demonstrated in the laboratory but only two, the gaseous diffusion process and the centrifuge process, are operating on a commercial scale. In both of these, UF6 gas is used as the feed material. Molecules of UF6 with U-235 atoms are about one percent lighter than the rest, and this difference in mass is the basis of both processes.\n\nLarge commercial enrichment plants are in operation in France, Germany, Netherlands, UK, USA, and Russia, with smaller plants elsewhere.

Sure.  "Studies on the interaction of U(VI) with living cells, spores, heat-killed cells, and decomposed cells of Bacillus sphaericus by time-resolved laser fluorescence spectroscopy show that different phosphate complexes are formed. Using fresh intact cells, the U(VI) is bound to organo-phosphate groups of the bacterial cells. With increasing age of the samples, the cells begin to lyse. During this process, inorganic phosphate is released and a uranyl phosphate precipitate is formed. The characterization of the released phosphate species by Raman spectroscopy and the uranyl phosphate complexes by time-resolved laser-induced fluorescence spectroscopy (TRLFS) has shown that the bacteria release H2PO4- during decomposition which leads to the formation of UO2(H2PO4)2."

They need approximately 3,000 more centrifuges to spin the gas made from uranium ore to reach 90% enrichment, today they stand at 3.5%. After that technical hurdle, it'll take them 1 to 2 more years to engineer the trigger or firing mechanism and to make a device small enough to be carried by an aircract or missile.\n\nThe current estimate is centrifuges by end of 2007.\nTrigger mechanism between 2009-2010\nEngineered for 'delivery' by 2012\n\nThey're close, but not very close, in fact, they're right on schedule to the timeframe analysts have been predicting for over a year now.

The use of uranium, in its natural oxide form, dates back to at least AD 79, when it was used to add a yellow colour to ceramic glazes (yellow glass with 1% uranium oxide was found near Naples, Italy). When this was rediscovered, in the earlier part of the 19th century, the world’s only known source of uranium 'earths' were the old Hapsburg silver mines in Joachimsthal, Bohemia, and the local glassmaking industry kept a tight lid on the secret ingredient and its supply as long as it could.\n\nThe discovery of the element is credited to the German chemist Martin Heinrich Klaproth who in 1789 found uranium in a mineral called pitchblende. It was named after Uranus the planet , which had been discovered eight years earlier by William Herschel. It was first isolated as a metal in 1841 by Eugene-Melchior Peligot. In 1850 the first commercial use of Uranium in glass was developed by Lloyd & Summerfield of Birmingham, England. Uranium was found to be radioactive by French physicist Henri Becquerel in 1896, who first discovered the process of radioactivity with uranium minerals.

Most nuclear weapons rely on fission (the breaking down of a nucleus into smaller nuclei).  This breakdown releases the energy that would otherwise go into holding the nucleus together.  That's not much energy for one nucleus, but breaking a few nuclei releases stray particles that bump into other nuclei and break them  -- which releases more energy, and more stray particles which bump into still more nuclei, and so on.  That's a chain reaction.  This reaction isn't limited to weapons; it also occurs in peaceful uses of nuclear technology such as reactors.  A nuclear weapon simply releases all of the available energy all at once.\n  As to predicting the reaction products, that's largely a function of what fissionable material you start with.  Nuclear physicists (which I am not) know what materials result from the nuclear decay of specific radioactive elements.  How you achieve fission is also a factor; a nucleus will break differently when hit by a fast neutron than it will when hit by a gamma ray.  Fusion is much simpler; if you start with hydrogen, the result is always helium.

I dont know much cuz im just in high school and not pro but heres my understanding:\nLets begin with the possibilities. Two sperm cells cleary would not work cuz of the YY issue and that wouldn't techniquelly be human anymore. However, in the female XX would be human. problem is The egg cell has a jelly coat whihc protects it. The one sperm cell that fertilizes uses enzymes to digest it away and the sperm cell must bind to a receptor site. Since we know very little about the protein world and how these receptors exactly work, just like we dont know how EXactly carrier proteins work in plasma membranes, its difficult to figure how to do it. Since implanting and fusing the two nuclei of the eggs would not initiate these receptor cyets, the zygote may not necessarly divide. It would just be a mutated egg like before and a sitting duck. You wouldn't get mitosis since it still techniquelly thinks its a gamete and wouldn't replicate. Also, too my understanding, the egg and sperm nuclei are drastically different in size and also chemical makeup may vary.Thats my assesment of the situation. Again, I'm not an expert but i think that might be enough to answer the question.

Sorry to be late, I didn't see your question till today. It works by creating steam. The core (nuclear material) is exposed and heats water in tubes. That water (steam) is generally used to heat water in a separate set of tubes. that steam is sued to turn turbines to created electricity. In a nutshell that is it. One side issue the "smoke" you see coming from nuclear power plants is steam. The water in the tubes is used over and over and never released.

you probably mean how do you enrich uranium?\n\nwhen uranium is mined from the ground as uranium ore, it is first processed and turned into uranium metal by electrolysis or thermal decomposition.  \n\nhowever, this uranium is actually made up of different kinds of atoms - uranium-238 and uranium-235 (and a little bit of U234).  these are called isotopes because they are the same element, but the nucleus of U238 contains 3 more neutrons than U235.  U238 is far more common - 99.3% of the naturally ocurring uranium is U238.\n\nfor uranium to be useful in a nuclear reactor or weapon, the content of U235 has to be increased to something like 3-7%.  this is because U235 is the less-stable isotope, and the one involved in nuclear reactions.  increasing the concentration of 235 is called "enrichment", and there are a couple of ways of doing it.\n\none way is to evaporate the uranium into a gas, and then let it diffuse down a very very long pipe.  because U235 is a lighter isotope, it will have a greater average velocity, and if the distance is long enough, the 235 will make it to the end of the pipe faster than the 238.  so that's one way of increasing the concentration.\n\nanother way is by centrifuging - you load the uranium up into a centrifuge, evaporate it again, and then spin it around really fast.  the denser 238 atoms sink to the bottom of the centrifuge tube, just like how water stays in the bottom of a bucket if you swing it around fast enough.\n\nyou can also use a modified type of mass spectrometer, but that's pretty specialized and is only really useful in a research setting.\n\nhowever, don't try this at home.  first of all, you can't just go out and buy uranium - it's sale is controlled by various governmental agencies and every scrap of it that moves around has to be approved by various levels of government.\n\nsecond of all, it's very dangerous stuff to be around - highly toxic and likely to cause cancer if mis-handled.  so stay away!

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.

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.

Whether it's uranium-235 or 238 makes no difference to the chemical formula. What determines the formula of the oxide is the most stable oxidation state of the metal, and with uranium these are +4 and+6, leading to formulae of UO2 and UO3.

fission is used in nuclear plants to make power. HOW FISSION WORKS: In a commercial nuclear power plant, a sufficiently large quantity of fuel material (usually enriched uranium) is accumulated in a reactor pile such that a "chain reaction" occurs, in which the neutrons emitted by a single fission reaction are captured by another nucleus to trigger another reaction, and so on. This solcomhouse.com link explains the basics of nuclear fission and has some good schematic illustrations of nuclear power plants.

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.

the water actually in with the uranium is in a closed circuit,  which when it gets heated by the rods boils in the reactor itself.  the steam goes through a pipe and the pipe heats another closed system of water.  This second system is not exposed to the radiation and this is what goes through the turbines and cooling tower.  This is so the turbines and all other external parts of the plant don't get exposed to radiation.  This is the reason why properly working nuclear power plants give off less radiation than coal plants.

I really don't know how those centrifuges look like, but they separate the Uranium into their isotopes (235 and 238) because of the different masses between them.\n\nTry this http://www.exportcontrols.org/centrifuges.html
