Uranium Enrichment & HALEU Tracker

Savannah River Site H-Canyon HEU-to-HALEU downblending

Program active · United States · Downblending

DOE plans to blend down about 2.2 tonnes of surplus highly enriched uranium at the Savannah River Site's H-Area to make about 3.1 tonnes of HALEU for advanced reactor fuel, under an amended record of decision issued in 2025. In February 2026 DOE said it would restart uranium recovery in H-Canyon, citing spent fuel holding enough HEU for up to 19 tonnes of HALEU.

Notes

haleu output = planned total (~3,100 kg) from the 2.2 t HEU campaign, not delivered output; no confirmed production start found. The 19 t HALEU figure is the potential from HEU in SRS spent fuel inventory (DOE, Feb 2026), not a commitment. H-Canyon previously downblended HEU to >300 t of LEU (2003-2011).
