# DOE Supports X-Energy Reactor Development

X-Energy’s Q3 2026 filing reports a wider $104 million operating loss and increased cash use while work continues under its Department of Energy (DOE) Advanced Reactor Demonstration Program cooperative agreement. The agreement provides up to $1.2 billion in cost-share reimbursement against eligible project costs; approximately $618 million had been reimbursed as of September 30, 2026. The current budget period runs through March 2027, and additional funding depends on DOE approvals and appropriations. The work supports Xe-100 reactor design, the TX-1 fuel facility in Oak Ridge, Tennessee, and the commercial demonstration project with Dow in Seadrift, Texas. The NRC announced construction permit approval for the Seadrift project on November 9, 2026. The filing identifies no open solicitation or procurement contact.

- Suppliers and subcontractors may find potential demand in reactor design, TX-1 facility construction, and long-lead materials, but the filing does not identify an active procurement opportunity.
- The current budget period ends in March 2027; companies evaluating project exposure should distinguish authorized, reimbursed cost-share funding from possible later funding, which is contingent on DOE approval and appropriations.
- X-Energy’s increased cash use and operating loss are relevant to suppliers assessing project and payment risk; the Seadrift project’s commercial operations are expected in the early 2030s, subject to project decisions and approvals.
