What it does

Directs DOE to build a domestic nuclear-fuel supply chain so the U.S. stops depending on Russia. It establishes a Nuclear Fuel Security Program, sets targets for making HALEU available (at least 10 metric tons by mid-2026, 20 MT by end of 2027), and expands the American Assured Fuel Supply. Crucially, it makes DOE act as a guaranteed first customer so private enrichers can finance new centrifuge plants.

Why it matters

Solved the 'chicken-and-egg' fuel problem: enrichers wouldn't build without buyers, and reactor developers couldn't commit without fuel. A common myth is that this passed via the ADVANCE Act — it didn't; it rode the FY2024 defense bill, a separate statute.
