Centrifuges use in nuclear power plant?

Centrifuges are used for enriching ura nium in the U-235 isotope. They work with gaseous uranium hexafluoride, if you have a long line of hundreds of centrifuges and pass the gas through them, you can gradually spin off some of the heavier U-238 resulting in a main stream with a greater percentage of U-235. This method has been used in Europe for many years and uses much less power than the older gaseous diffusion method which has been continued in the US, but I think that is now changing to centrifuges. This is what the State Dept is so concerned about happening in Iran. If you have enough centrifuges you can get nearly pure U-235 out which of course can be used in weapons.


What do scientists have to do with the uranium before using in a nuclear bomb?

To use natural uranium in a bomb either of 2 things must be done first, both are expensive and require large infrastructure investment to do them:Enrich the uranium from 0.72% uranium-235 (natural) to 93.5% uranium-235 (Oralloy or HEU).Process the uranium to turn some of the uranium-238 to plutonium-239 in a reactor then chemicallly separate the plutonium from the rest of the irradiated material chemically.In WW2 the US did step 1 at Oak Ridge, TN using a gigantic gaseous diffusion enrichment plant and an electromagnetic separation plant; and step 2 at Hanford, WA using several graphite moderated reactors and large chemical separation plants called "canyons".

None, this was not considered practical in the 1940s.

How many Iraqi children have died as a result of the United States using depleted uranium?

You'll have to make your question more clear. Are you talking about depleted uranium munitions? Or are you claiming the US are using depleted uranium for something else?

Did Iraq have nuclear weapons?

Saddam Hussein had the materials necessary to build nuclear weapons - the invasion prevented him from attaining the proper machines necessary to complete weapons manufacturing. Just this past summer, it was learned that in the early days of the Iraq war, US forces seized 55 tons of Uranium yellowcake, a low-grade ore. While not suitable for weapons, it can be enriched by using a centrifuge of certain capability. Centrifuges to enrich the yellowcake to weapons-grade nuclear material wasn't obtained by Iraq, though had the invasion not happened it would've happened eventually. The yellowcake was guarded by US forces from the beginning of the war until this past summer, when a deal was reached with Canada (with the agreement of the new Iraqi government) to sell the Uranium and get it out of the country. The reason that it had been closely guarded and a secret is that neighboring Iran DOES have the kinds of centrifuges to enrich material to weapons grade. It would have been a major disaster had that material found its way into terrorist hands. Whether he was able to procure tactical nukes or those of smaller design is not known publicly; such information is rarely released to the public, even if politically advantageous to do so. However, since the US and other countries have the ability to find nuclear weapons by a variety of classified means, it's a safe bet that if he did, they're gone now, either found by Coalition forces or moved out of the country to a neighboring Arab state.


How much does uranium cost per gallon?

Uranium is a solid, not a liquid. So it is sold by weight, not by volume. As of 25 July 2011 Uranium costs US $ 51.50per US pound or US $113 per kilogram of natural uranium in the form of the unrefined uranium oxide (U3O8).


Is uranium mining good for us?

Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and radioactive chemical element. 3. Uranium release radium and radon.
