* Partnership with Alleima and Doosan Enerbility for long-lead components * Secures safety-significant components essential for high-temperature industrial applications ROCKVILLE, Md., Nov. 04, 2026 (GLOBE NEWSWIRE) -- X-Energy, Inc. (Nasdaq: XE) (“X-energy” or the “Company”), a leading developer of advanced nuclear reactors and fuel technology, Alleima, a global manufacturer of advanced stainless steels and special alloys and solutions for industrial heating, and Doosan Enerbility Co., Ltd. (“Doosan”) announced the first procurement of steam generator tubing for the Company’s Xe-100 advanced small modular reactor (“SMR”). The order advances procurement of a safety-significant, long-lead component for the first deployment of the Xe-100, a proposed four-unit plant in partnership with Dow in Texas under the U.S. Department of Energy's Advanced Reactor Demonstration Program (“ARDP”).
Alleima will leverage its expertise in high-temperature alloys to manufacture specialized stainless steel tubing, which Doosan will bend into helical coils using its proprietary fabrication processes. These coils are a central component of the Xe-100 steam generator, safely removing heat to produce high-temperature steam of up to 565°C and allowing a single Xe-100 to deliver both electricity and high-temperature process heat for industrial applications. This follows the signing of a strategic framework by the three companies earlier this year as the Company scales its supply chain to meet its growing commercial pipeline.
