Frequently Asked Questions About Gas Centrifuge Enrichment Plants
Currently, the only operating gaseous diffusion enrichment plant in the United States is the plant in Paducah, Kentucky. Another way to enrich uranium is by using gas centrifuges. Gas centrifuges spin UF 6 gas at high speeds creating a centrifugal force that separates the isotopes by forcing the heavier U-238 further outward in the centrifuge.
