Terrestrial uranium [U] mineral deposits are composed of 99.3% U-238, and 0.7% of U-235.
Both are naturally occurring isotopes. The scarcer U-235 is needed for nuclear fission.
Natural-mined uranium must undergo an "enrichment" process to increase its U-235 concentration to > 3% before it can be used as nuclear fuel.
U-238 has a half-life of 4.468 billion years. U-235 has a half-life of 703.8 million years.
