From 2003 to 2011, staff at the Department of Energy’s Savannah River Site downblended high-enriched uranium in the site’s H Canyon, producing over 300 metric tons (MT) of low-enriched uranium that was fabricated into fuel. The facility has since been idled, but downblending could soon begin again—this time to high-assay low-enriched uranium (HALEU).
