Who Will Build Centrus Energy's Massive Uranium Enrichment Expansion?

Centrus Energy Corp (NYSE: LEU) has selected Geiger Brothers, Inc. as the construction contractor for its multi-billion-dollar expansion of uranium enrichment capacity at the Piketon, Ohio facility. The announcement comes as the U.S. seeks to reduce dependence on Russian-supplied HALEU fuel while meeting accelerating demand from advanced nuclear reactors and data center operators.

The Piketon expansion represents the largest domestic uranium enrichment capacity addition since the original facility's construction. Centrus operates the only commercial-scale HALEU production facility in the United States, currently producing High-Assay Low-Enriched Uranium enriched up to 19.75% U-235 for advanced reactor demonstrations. The expansion will significantly increase this production capacity, though Centrus has not disclosed specific SWU (Separative Work Units) targets or completion timelines.

Geiger Brothers brings industrial construction expertise to the project, joining Centrus' strategic partnership network that already includes ConverDyn for uranium conversion services. The contractor selection marks a critical milestone for establishing America's HALEU supply chain independence, particularly as SMR developers including NuScale, X-energy, and TerraPower advance toward commercial deployment requiring reliable fuel supplies.

Construction Timeline and Strategic Positioning

The Piketon expansion builds on Centrus' existing American Centrifuge technology, which uses gas centrifuge enrichment rather than older gaseous diffusion methods. This approach delivers higher energy efficiency and lower operational costs compared to legacy enrichment facilities. The facility already produces HALEU for DOE's Advanced Reactor Demonstration Program, supporting TerraPower's Natrium reactor and X-energy's Xe-100 development.

Geiger Brothers' selection follows extensive due diligence on technical capabilities and cost optimization potential. The construction firm has experience with nuclear-grade industrial facilities, though this represents their largest uranium enrichment project. Industry sources indicate the multi-billion-dollar investment could position Centrus to capture 15-20% of projected U.S. HALEU demand through 2035.

The timing aligns with accelerating SMR deployment schedules. NuScale expects initial VOYGR plant operations by 2030, while Kairos Power targets commercial TRISO fuel production requiring HALEU feedstock. Data center operators including Microsoft and Amazon are evaluating nuclear partnerships that could drive additional HALEU demand beyond traditional utility applications.

Market Implications and Supply Chain Security

Centrus' expansion addresses a critical bottleneck in American nuclear fuel supply chains. Russia's Tenex currently dominates global HALEU production, creating supply security risks for U.S. advanced reactor programs. The Inflation Reduction Act included $700 million for domestic HALEU production infrastructure, though industry analysts estimate total required investment exceeding $3 billion through 2035.

The project's economics depend heavily on long-term HALEU purchase commitments from utilities and reactor developers. Centrus has secured initial DOE contracts totaling $150 million, but commercial-scale production requires PPAs spanning 10-20 years. Early data suggests HALEU pricing at $4,000-6,000 per kilogram versus $200-300 for standard LEU fuel, reflecting enrichment complexity and limited supply competition.

Uranium market dynamics also influence project viability. Spot uranium prices reached $106 per pound in early 2024 before stabilizing around $85-90 per pound. Higher uranium costs increase HALEU production expenses, though advanced reactor fuel represents less than 5% of total LCOE for most SMR designs.

Technology and Competitive Landscape

The American Centrifuge technology deployed at Piketon offers modular scalability advantages over competing enrichment methods. Each centrifuge cascade can be independently operated and maintained, reducing operational risks compared to large gaseous diffusion plants. Centrus estimates 40% lower electricity consumption versus legacy enrichment technologies.

Competitive pressures from Urenco's proposed U.S. HALEU facility and potential new entrants could affect long-term market share. However, Centrus' first-mover advantage and existing NRC licensing provide significant barriers to entry. The company holds licenses for uranium enrichment up to 20% U-235, covering virtually all advanced reactor fuel requirements except defense applications.

International competition remains limited but growing. France's Orano operates HALEU production capabilities, while China's CNNC has announced domestic HALEU programs supporting their SMR export strategy. Geopolitical factors increasingly favor domestic supply chain development, supporting Centrus' investment thesis despite higher production costs versus established suppliers.

Frequently Asked Questions

Why is HALEU fuel important for advanced nuclear reactors? HALEU enriched between 5-20% U-235 enables smaller reactor cores, longer fuel cycles, and passive safety systems that are impossible with standard 3-5% enriched uranium. Most SMR designs require HALEU to achieve economic and safety targets.

How much HALEU capacity does the U.S. currently have? Centrus operates the only commercial-scale HALEU production in America, producing limited quantities for demonstration reactors. The Piketon expansion aims to meet projected demand from commercial SMR deployments starting in 2030.

What are the alternatives to Centrus for U.S. HALEU supply? Currently, Russian Tenex dominates global HALEU production. Urenco has proposed U.S. facilities, and DOE is evaluating down-blending of highly enriched uranium stockpiles, but Centrus represents the primary near-term domestic option.

How does HALEU production differ from standard uranium enrichment? HALEU requires additional centrifuge stages and specialized handling procedures due to higher U-235 concentrations. The process is more complex and energy-intensive than producing standard reactor fuel.

When will the Piketon expansion be operational? Centrus has not disclosed specific completion timelines, though industry sources expect initial expanded production by 2028-2030 to align with SMR commercial deployment schedules.
