Company Description
X-energy, founded in 2009, is a nuclear energy company that designs and engineers advanced reactors and fuel. The company is currently focused on its Xe-100, a Generation IV high-temperature gas-cooled small modular reactor (SMR), and its proprietary TRISO-X fuel. This fuel is designed to be meltdown-proof by sealing uranium particles within a protective coating. Headquartered in Rockville, Maryland, the company was established by Kam Ghaffarian to develop safer and more affordable nuclear power solutions. X-energy has since expanded its operations, with offices in the United States, Canada, and the United Kingdom, and has grown to employ between 501 and 1,000 people.
Looking forward, X-energy plans to scale the deployment of its Xe-100 reactors and expand the application of nuclear energy into areas like hydrogen production and industrial heat. The company's strategy includes modular construction to reduce costs and deployment timelines. A recent binding agreement with Doosan Enerbility will support this goal, with Doosan set to manufacture steel components for 16 Xe-100 reactors and construct a new SMR fabrication facility in South Korea. These efforts are intended to support projects with partners such as Dow and Amazon. The company also recently appointed Daniel Gross, formerly of Amazon, as its Chief Financial Officer and is actively recruiting for over 100 open positions to support its growth.
