Uranium's Atomic Basics
- Uranium is the heaviest natural element with atomic number 92 and has two natural isotopes, U-238 and U-235.
- The difference in their nuclear properties underlies uranium's use in power and weaponry.
Fissile vs Fertile Isotopes
- Only uranium-235 is fissile and can sustain chain reactions by splitting and releasing neutrons.
- Uranium-238 is fertile and can convert into plutonium-239, another fissile material.
Enriching Uranium Explained
- Enrich uranium hexafluoride gas via centrifuge to separate lighter U-235 from heavier U-238.
- Enrichment is technically demanding and differentiates reactor fuel from bomb-grade uranium.
