X-energy Reactor Company, LLC (“X-energy” or the “Company”), a leading developer of advanced small modular nuclear reactors and fuel technology for clean energy generation today announced the purchase of a property in Frederick, Maryland that will house the Company’s newest integrated test and training facility to validate key components and systems of X-energy’s Xe-100 advanced small modular reactor for commercial deployment. This follows a $6.15 million incentive agreement with Maryland Gov. Wes Moore and local leaders to support X-energy’s continued growth in Maryland, including the retention and expansion of X-energy’s headquarters in Montgomery County, and an expanded presence in Frederick County with the new state-of-the-art test facility.

The Frederick, Maryland, facility that will house X-energy's newest integrated test and training center.
X-energy’s new 90,000 square foot non-nuclear test & training facility will ensure key components of the Xe-100 perform safely and reliably under real-world conditions before full-scale manufacturing and deployment. Once fully renovated, the building will house a helium test facility (“HTF”) for full-scale integrated systems testing in a pressurized helium environment, as well as an experimental test facility (“XTF”) for testing and prototyping of critical reactor components and materials. The facility will also provide training for Xe-100 operators and maintenance technicians using a state-of-the-art, full-scale plant control room simulator similar to the advanced training simulator currently operating at X-energy’s Plant Support Center, also in Frederick.
“X-energy’s expansion in Montgomery and Frederick counties is an investment in Maryland and in our state’s vital energy and sustainability sector,” said Gov. Moore. “While X-energy works to power our future, we will work hand in hand to make sure all Marylanders feel the benefits of clean energy for years to come and enhance our competitive edge across the region.”
Under the agreement, X-energy will receive a total of up to $6.15 million in state and local support in the form of job creation tax credits, conditional loans, and grants. The Company has partnered with real estate broker Avison Young to purchase the site in Frederick County. Major renovations will begin this year, and initial testing at the XTF is expected to begin in early 2026. X-energy will also expand its headquarters in Montgomery County to support its growing Maryland-based team, moving its operations from two locations in Rockville to a centralized location at Washingtonian Center in Gaithersburg.
“X-energy was founded in Maryland, and we are proud to call this state our home as we enter a period of unprecedented growth,” said J. Clay Sell, CEO of X-energy. “We look forward to working with Governor Moore and his team to build on the state’s long history of nuclear innovation by making Maryland a national leader in next-generation nuclear technology.”
X-energy is advancing its initial Xe-100 plant at Dow Inc.’s UCC Seadrift Operations manufacturing site on the Texas Gulf Coast. Once complete, the plant is expected to provide the site with safe, reliable, and clean power and industrial steam. X-energy is also advancing its second plant in central Washington with Energy Northwest in collaboration with Amazon. This project is part of a larger strategy with Amazon to bring more than five gigawatts of new power projects online by 2039, furthering the company’s mission to provide scalable, secure, clean energy solutions that meet the growing demand for energy across the U.S. and around the world.
