Centrus Energy Corp. has selected Geiger Brothers for the $900 million uranium enrichment plant expansion. Centrus Energy is a wholly owned subsidiary of the American Centrifuge Operating LLC. Both firms signed a Construction Contract that caps aggregate payments at $900 million through January 30, 2031. On the other hand, the scope of implementation by the Geiger Brothers in the expansion includes various aspects.

The firm is mandated to refurbish existing facilities, install equipment and build new infrastructure. Furthermore, they are to do this under a time-and-material structure with agreed labor and markup rates supplemented by future task releases. Fluor Corporation also continues as Engineering, Procurement, and Construction (EPC) contractor.

Once complete, the expansion is expected to support Centrus’ $2.3 billion commercial LEU backlog and at least 12 metric tons per year of HALEU production capacity.

Other Projects:

Energy projects across the United States are becoming of essence as the nation turns to various avenues in power production. Other than uranium, natural gas-fired plants are becoming a viable avenue such as the proposed Hawaiian gas-fired power plant in Oahu. Japan’s largest power generation company has made a proposal to invest $2bn for a Hawaii gas-fired power plant in Oahu. The investment is for a 500-MW combined-cycle and simple-cycle natural gas-fired power plant in the U.S. Tokyo-based JERA noted the project comes after the company made an agreement with Hawaiian officials last fall.

Scope into the Enrichment Plant Expansion by Geiger Brothers

The uranium enrichment plant expansion by the Geiger Brothers will add thousands of AC100M centrifuges at its American Centrifuge Plant in Piketon. The project’s aim is to restore America’s ability to enrich uranium at a large scale with domestic technology.

Fluor and Geiger Brothers will also work alongside Centrus’ existing manufacturing and engineering teams to advance the next phase of construction. Centrifuge manufacturing to support the expansion launched in December 2025 at Centrus’ centrifuge manufacturing plant in Oak Ridge, Tennessee. Geiger Brothers reel back into the project having served a key role as construction partner in the existing HALEU cascade.

They also participated in an earlier LEU demonstration cascade which was completed in 2013.  “We are proud to support this historic investment in America’s nuclear fuel supply chain,” said Erik Massie, President and Chief Financial Officer of Geiger Brothers. “Our roots are in Ohio, and we look forward to contributing to a project that strengthens U.S. energy security, creates local jobs, and bolsters domestic manufacturing.”
