Radioactivity Question...

What is the different between Uranium-235 and Uranium-238   in terms of the fission process?  You must refer to the difference between “fissionable” and “fissile” in your answer.

Uranium-235 is more appropriate for nuclear fission and it is more fissile than Uranium-238. In enrichment, it involves increasing the percentage of uranium-235 so that it is able to be at a volume where it can sustain nuclear fission. Uranium-238 is only really good for creating Plutonium-239, which is the fuel used in fast breeder reactors.
