Purpose
Nuclear Power Plants are used to power millions of homes.

Energy Conversions
Heat into steam. Steam into the spinning of a steam turbine. The turbine spins a magnet and creates electricity.

Controls
The sensors in nuclear power plants are heat and radiation sensers. They are used to automaticly shut down the power plant, saving money, lives, and land from a nuclear meltdown.

Materials
Urainium, http://periodictable.com/Samples/092.19/s13.JPG

water, building materials (for building).

Science
Nuclear fission is used to heat up water into steam ant turn a turbine, which turns a magnet which creates electricity. Try Electromagnetism for more. Nuclear fission involves the splitting of a heavy element into lighter elements. The reaction is set off by the random capture of a stray neutron.For instance, in the above reaction, a uranium atom captures a neutron and for a brief while exists as uranium-236, an unstable isotope. This unstable isotope then "fissions" into the smaller elements barium and krypton and releases 3 more neutrons. This reaction results in the creation of 10 BILLION KJ per mole of energy. Notice that more neutrons are released by the fission process. These neutrons go on to react with other uranium atoms and continue the process. One might imagine that with each successive reaction more and more neutrons would be produced, and consequently more and more fissioning of uranium would occur. In a nuclear weapon, that is exactly what would happen. However, in nuclear power plants the reactions are controlled. Reactive uranium rods are alternated with absorbent carbon or lead rods. Thus, although some neutrons continue to react and continue the fission reaction, others are absorbed, and the reaction does not get out of control. The energy produced by fission is used primarily to heat a liquid (usually water) to boiling. The steam generated by the boiling liquid is used to power a turbine that generates electricity. [|//**What is Nuclear Energy**//?] is a good place to check out. Design The urainum heats up the water in the nuclear reactor and the result is steam, lots and lots of steam. The steam spins turbines like giand propelers. The turbines spin magnets.

Evolution
Nuclear power has gotten safer.

=Riskes= Nuclear meltdown, radiation, and waste. The radiation from a nuclear power plant can cook you the same way a Microwave Oven does, but only in a nuclear meldown and only if you are close enough (in the plant). In Chernobyl in 1986, three years before the Tienanmen square massacre, and the Berlin falling, down.
