Savannah River Site AI Campus

DOE picked Amentum and DC BLOX in July 2026 to negotiate a lease for a proposed 1 GW federal-land AI campus in South Carolina.

Lease talks only. The National Nuclear Security Administration selected Amentum on July 20, 2026 to negotiate a phased lease, and said the selection is not an award. As of Oct. 18, 2026 no lease, environmental review, tenant, financing or construction start has been announced.
