Nucelar Energy

nuclear reactor nuclear reactor, device for producing NUCLEAR thrust by controlled nuclear reactions. It finish be used for either research or exponent production. The reactor is so constructed that the fission of atomic nuclei produces a independent nuclear chain reaction, in which the produced neutrons are able to stock split other nuclei. A fission reactor consists basically of (1) a elicit, usually uranium or plutonium, enclosed in protect; (2) a moderator--a sum such as graphite, beryllium, or gruelling water--that slows down the neutrons so that they may be more substantially captured by the fissionable atoms; and (3) a cooling system that extracts the horniness energy produced. The fuel is sometimes enriched--i.e., its concentration of fissionable isotopes is unnaturally increased--to increase the relative frequency of neutron capture. The breeder reactor is a surplus type of reactor that produces more fissionable atoms than it consumes by utilise surplus n eutrons to exchange certain nonfissionable atoms into fissionable atoms. The build of fusion reactors is shut up in an experimental stage because of the problems twisting in containing the plasm fuel and attaining the high temperatures needed to open up the reaction.
