11. In particular, Khan had been selling gas centrifuge technology to North Korea, Iran, and Libya. 12. Nuclear inspectors interviewed two engineers who worked on Iraq's gas centrifuge enrichment program, he said. 13. In fact, gas centrifuges using uranium hexafluoride have largely replaced gaseous diffusion technology for uranium enrichment. 14. These aerodynamic separation processes depend upon diffusion driven by pressure gradients, as does the gas centrifuge . 15. Next, that undergoes isotope separation through the process of gaseous diffusion, or in a gas centrifuge . 16. Shingaryov said, adding that Iran opted for more feasible technology using gas centrifuges to enrich uranium. 17. That's the same weight as the magnets used in Iraq's gas centrifuge program before the Gulf War. 18. Gas centrifuges are used in uranium enrichment.19. For those who want doomsday weapons, however, the appeal of uranium gas centrifuges lies in their compactness. 20. The industrial applications of motors with these parameters are diverse, and may include pumps or gas centrifuges .
