Ikhtisar

Uranium enrichment increases the concentration of the fissile isotope U-235 from its natural abundance of 0.72% to 3-5% for nuclear power reactor fuel. The gas centrifuge process converts uranium oxide (yellowcake) to uranium hexafluoride (UF₆) gas, which is spun in high-speed centrifuges to separate the lighter U-235 from the heavier U-238. Thousands of centrifuges are connected in cascades to achieve the required enrichment. This technology provides fuel for approximately 440 nuclear power reactors worldwide, generating 10% of global electricity.

Proses Kimia

Yellowcake (U₃O₈) is converted to UF₆ by reaction with HF and F₂. The UF₆ gas is fed into Zippe-type centrifuges spinning at 50,000-70,000 rpm. Heavier U-238F₆ concentrates at the wall while lighter U-235F₆ concentrates near the axis, separated by countercurrent flow. Each centrifuge achieves a separation factor of 1.3-1.5. Cascades of 1,000-50,000 centrifuges produce 3-5% enriched UF₆, which is converted back to UO₂ for fuel pellet fabrication.

U₃O₈ + 2UO₃ + 18HF + 3F₂ → 6UF₆ + 9H₂O (conversion to UF₆)
Centrifugal separation: ²³⁵UF₆ (lighter) separates from ²³⁸UF₆ (heavier) — mass difference of only 0.86%

Bahan Baku

  • Uranium hexafluoride (UF₆) — Conversion of yellowcake (U₃O₈) with F₂ and HF (Feed material for enrichment)
  • Yellowcake (U₃O₈) — Uranium mining and milling (Uranium source (0.72% U-235))

Produk Akhir

  • Enriched UF₆ (3-5% U-235) — Nuclear fuel fabrication for power reactors (LEU (low-enriched uranium) for light water reactors)
  • Depleted uranium (0.2-0.3% U-235) — Radiation shielding, military applications, stored for future use (Tails, stored as UF₆ or UO₂)

Environmental Impact

Uranium mining generates radioactive tailings and mill waste. Enrichment produces large quantities of depleted uranium (DU) requiring long-term storage. UF₆ is toxic and radioactive. However, nuclear power produces no direct CO₂ emissions and has one of the lowest life-cycle carbon footprints of any electricity source.

Pertimbangan Keselamatan

Inovasi Terbaru

SILEX (separation of isotopes by laser excitation) promises more energy-efficient enrichment.
Accident-tolerant fuels (ATF) with chromium-coated cladding improve nuclear safety.
High-assay LEU (HALEU, 5-20% U-235) is being produced for advanced small modular reactors (SMRs).
