Uranium is enriched to increase the concentration of the isotope uranium-235, which is necessary for nuclear reactions. Natural uranium consists mostly of the isotope uranium-238, which is not as easily fissionable as uranium-235. By enriching uranium, the concentration of uranium-235 is increased, making it suitable for use in nuclear reactors and weapons. This enrichment process allows for more efficient and controlled nuclear reactions. **
