X-energy, Fluor Corporation Advance Nuclear Engineering and Design for Second Xe-100 Project

X-energy selected Fluor to provide design & engineering services for Energy Northwest's Cascade Advanced Energy Facility near Richland, Washington.
The project utilizes the Xe-100 advanced small modular reactor & marks a second-of-a-kind deployment following the first proposed Texas project.
Fluor will deliver engineering, design development, supply chain, estimating, & project controls services for the nuclear island.
Cascade Nuclear Partners, a joint venture of Kiewit Nuclear Solutions, Black & Veatch, & Aecon, serves as the progressive design-builder for the conventional island.
The agreement enables the incorporation of learnings from the first project to support accelerated long-term standardized execution & cost reductions.
X-energy's Xe-100 is an 80 MWe high-temperature gas-cooled reactor powered by TRISO-X fuel designed for standardized four or twelve-unit plants.
The Cascade facility is the first project in X-energy's collaboration with Amazon to deploy 5 GW of new nuclear capacity by 2039.
X-energy currently maintains a commercial pipeline of 11.5 GW equivalent to 144 Xe-100 reactors.
A second project with American Electric Power was recently announced in Indiana.
Early engagement with engineering partners aims to ensure components, capabilities, & expertise are available as projects advance through commercial milestones.
