Fueling the Future of Nuclear Power

Medium/Long Term: Feed Costs Will Drive Overall Costs 1 KgU HALEU (19.75% U-235) 6 SWU 35 SWU HALEU Enrichment 4.95% into 19.75% LEU Feed 4.5 KgU at 4.95% U-235 • The feed material for a HALEU cascade is 4.95% LEU. LEU feed could be produced on site by an adjacent cascade or purchased elsewhere. • 85% of the SWU needed to produce HALEU is already contained in the LEU feed material. ⚫ KEY TAKEAWAY: As we continue to scale up, the biggest factor in fuel costs of commercial advanced reactors will be the market price of 4.95% LEU (natural uranium + conversion + LEU enrichment), not the cost of HALEU enrichment.
