    The vast majority of nuclear power reactors use the isotope uranium-235 as fuel however it only makes up 0.7 of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium-235 concentration from 0.7 to between 3 and 5 which is the level used in most reactors.
