Savannah River Site HEU downblending
Capacity
3,100kg HALEU total
Savannah River Site HEU downblending is a haleu facility operated by US Department of Energy in United States. It has a capacity of 3,100 kg HALEU total as of 2026.
Diluting surplus weapons-grade material down into reactor fuel. This is a stopgap, not a supply chain: the stock is finite and non-renewable, intended to bridge the gap until commercial enrichment capacity exists.
