X-energy completes key safety system prototype for Xe-100 Advanced Nuclear Reactors

ROCKVILLE (Md.), December 21, 2022–(BUSINESS WIRE)–X-Energy Reactor Company, LLC (“X-energy” or the “Company”), a leading developer of small modular nuclear reactor and fuel technology for clean energy generation, in partnership with Paragon Energy Solutions (“Paragon”), a leading specialist in the design and manufacturing of critical safety systems, today announced the completion of a Reactor Protection System (“RPS”) prototype, a key safety feature of X-energy’s Xe-100 advanced nuclear reactors. The four-division RPS prototype utilizes Paragon’s highly integrated protection system (“HIPS”) and marks the first time that Paragon has deployed HIPS to a Generation IV high-temperature gas reactor (“HTGR”), an evolution of their robust, reliable, and secure technology that is intended to further advance nuclear safety.

X-energy worked with Paragon for two years to develop, deliver, install, and test the RPS prototype in the Company’s control room simulator at its Rockville, Maryland headquarters. Paragon has been selected to construct and deliver the RPS in four divisions to all Xe100 plant around the world once they are deployed.

J. Clay Sell, CEO of X-energy, stated that the completion of these crucial safety mechanisms was yet another example of the innovative nuclear technology they are bringing to market. Safety is the main objective of our company, our employees, and our products. Paragon has developed a system that’s more efficient, secure, and cheaper than the legacy systems of older nuclear power stations. Our system is designed for safe and secure operation at all times.

RPS is a combination of redundant and independent instrumentation and control parts that allows the nuclear reactor’s safe and automatic shutdown. This provides an additional layer of protection for both the plant and the environment. RPS uses Paragon’s HIPS platform based on Field Programmable Gate Array (FGPA) technology. FPGA-based systems are more robust and resilient than older nuclear power plant systems. They also reduce cyber-attacks and lower the risk of disruption. A HIPS FPGA-based platform is safer and more efficient because it is hardware-only, with no run-time code. The system’s structure and design insulate it from coding errors and reduce cybersecurity risks, thus addressing regulatory concerns about digital safety systems.

“Paragon is committed to supporting a zero-carbon energy future, and is working to develop innovative nuclear solutions that are safer, more reliable, and more cost-efficient,” said Doug VanTassell, Paragon’s President and CEO. “We are delighted to be a partner in the successful deployment of modular small nuclear reactor technology, as we enter into this long-term strategic partnership with Xenergy.

The prototype delivery is a milestone in X-energy’s progress toward completing the Department of Energy’s Advanced Reactor Demonstration Program (“ARDP”). The DOE selected Xenergy to receive $1.2 billion in federal cost-shared funding. This will allow X-energy develop, license, build and operate a Xe-100-based nuclear power plant. It is expected to be operational by the end the decade. X-energy plans to show its capabilities. Xe-100 HTGRs in the program by 2028

The Xe-100 design is a pioneering combination of scalability, innovation, modularity and higher temperatures. It also draws on decades of HTGR research experience and operating experience. The reactor is fueled by X-energy’s proprietary TRISO-X fuel, which has been called “the most robust nuclear fuel on earth” by the U.S. Department of Energy. The Xe-100 can be operated as a single 80-megawatt (MWe) unit. It is also optimized to run as a four-unit plant that delivers 320 MWe.

As before announcedX-Energy and Ares Acquisition Corporation have entered into a definitive business partnership agreement (“AAC”) that will make X-Energy a public company. The transaction is expected to close in the second quarter 2023. The combined company will be called X-Energy, Inc. Common equity securities and warrants will also be listed on the NYSE.
