Their experience across boiling water reactor (BWR), pressurized water reactor (PWR) and CANDU reactor systems aligns with the established light-water technology underpinning Hadron’s Halo design. By expanding its internal engineering capabilities, the company aims to strengthen the technical foundation required to develop reactor components, demonstrate compliance with applicable nuclear standards and prepare the system for factory-based production.
Strengthening the Engineering Foundation for Halo
Developing a commercial microreactor requires more than establishing a reactor concept. The design must be translated into physical components that meet stringent engineering requirements, withstand operating conditions and satisfy regulatory expectations. Reactor vessels, internal structures, mechanical systems, piping and other pressure boundary components must be designed, analyzed, manufactured and evaluated throughout the development process.
Hadron Energy’s three new engineering leaders will contribute specialized expertise across these critical disciplines. Their responsibilities include designing the reactor vessel and internal components, developing mechanical and thermal-fluid systems, and conducting stress, fatigue and fracture mechanics analyses to assess structural integrity.
The expanded team will also support interactions with regulators and nuclear component suppliers. These activities are essential as Hadron advances the Halo design toward the engineering documentation, component specifications and manufacturing processes needed for future deployment.
Sam Gibson, Founder and Chief Executive Officer of Hadron Energy, emphasized the importance of experienced engineers in commercializing microreactor technology. He explained that the new team members bring practical knowledge of designing reactor components, supporting regulatory reviews and working through hardware fabrication.
According to Gibson, the engineers joined Hadron to apply their experience to a light-water microreactor designed for factory production and timely deployment. Their addition is intended to help the company accelerate development of a reactor that can progress through licensing, manufacturing and delivery to customers seeking dependable, around-the-clock electricity.
Eric Williams, Executive Vice President of Engineering at Hadron Energy, also highlighted the team’s complementary capabilities. He noted that the engineers have prepared ASME Section III design specifications, supported reviews by the U.S. Nuclear Regulatory Commission (NRC) and collaborated with component fabricators to ensure hardware meets engineering requirements.
Williams said their combined experience provides technical leadership for advancing Halo’s design and executing the company’s licensing and supply chain plans.
Kent Olson to Lead Reactor Vessel and Component Design
Kent Olson, P.E., joins Hadron Energy as Director of Component Design. He brings 20 years of engineering experience, including 10 years in the nuclear industry, with a background in commercial reactor systems and the U.S. Naval Nuclear Propulsion Program.
Most recently, Olson served as Reactor Design Engineering Manager at GE Hitachi Nuclear Energy. In that role, he was responsible for the reactor vessel, internals and penetrations, oversaw ASME Code-related activities, and supported regulatory reviews involving the NRC and the Canadian Nuclear Safety Commission.
Olson has led multidisciplinary engineering teams of more than 40 engineers working on reactor pressure vessels, internal structures and ASME Section III Class 1 components. His experience includes coordinating complex design activities across different engineering disciplines and managing requirements associated with nuclear-grade components.
One of his notable accomplishments involved accelerating reactor vessel design and fabrication schedules by two years through the use of concurrent engineering. This approach allows related engineering activities to progress in parallel, potentially reducing delays between design development, component preparation and manufacturing.
Earlier in his career, Olson worked at Bettis Atomic Power Laboratory, where he designed nuclear servicing equipment for the U.S. Navy.
At Hadron Energy, Olson will lead the design of the Halo MMR’s reactor vessel, internal structures and major components. His responsibilities will support the development of a reactor configuration that can meet technical requirements while progressing toward manufacturability and deployment.
Stephen Moore to Lead Mechanical and Thermal-Fluid Systems
Stephen Moore, P.E., has joined Hadron Energy as Principal Mechanical Engineer. He brings 12 years of engineering experience, including five years in the nuclear sector, with specialized knowledge of mechanical systems and nuclear component design.
Moore previously worked at TerraPower, where he contributed to the development of the Natrium reactor. As Lead Pump Engineer, he led design activities and engineering oversight for the reactor’s primary and intermediate reactor coolant pumps. He also prepared design specifications under ASME Section III, Division 5 requirements.
His experience extends to primary heat transport system engineering, reactor instrumentation and the design of components associated with pumps, heat exchangers, reactor vessels and internal structures.
These systems are central to reactor operation because they help manage heat transfer and support the movement of fluids through interconnected components. Their design must account for operating conditions, mechanical loads, performance requirements and applicable engineering standards.
Moore is also a named inventor on multiple U.S. patent applications and holds a professional engineering license.
At Hadron Energy, he will lead the design of thermal and fluid mechanical systems and components for the Halo MMR. His expertise is expected to support the integration of mechanical equipment and heat-transfer systems into the overall reactor architecture.
By strengthening this area of engineering, Hadron aims to advance the detailed design work needed to translate the Halo concept into a practical nuclear energy system.
Dr. Yifan Huang to Lead Component Integrity Analysis
Yifan Huang, Ph.D., P.E., P.Eng., joins Hadron Energy as Principal Component Analysis Engineer. He brings 10 years of nuclear industry experience and specializes in structural integrity, fracture mechanics and the assessment of reactor pressure boundary components.
Huang has worked across BWR, PWR and CANDU reactor systems. Most recently, he served as a Principal Engineer on Framatome’s fracture mechanics team. Previously, he managed more than 30 engineers as Engineering Manager of Reactor Component Integrity at Candu Energy, an AtkinsRéalis company.
At GE Hitachi Nuclear Energy, Huang led the development of a leak-before-break methodology for piping associated with the BWRX-300 small modular reactor. This engineering approach evaluates whether certain piping flaws would be expected to produce detectable leakage before progressing to a more serious structural failure, subject to the applicable technical assumptions and acceptance criteria.
His work earned him GE Hitachi’s 2024 Emerging Engineer Award.
Huang is also an adjunct research professor at the University of Western Ontario and has authored 27 technical publications, reflecting his involvement in both engineering practice and research.
At Hadron Energy, he will lead stress, fatigue and fracture mechanics analyses of Halo’s pressure boundary components and piping. These evaluations are intended to help demonstrate that critical components can withstand anticipated mechanical loads and operating conditions throughout the plant’s service life.
His expertise will support the technical assessments needed for component design verification and regulatory documentation.
Advancing Manufacturing Readiness and Licensing
The addition of the three engineers gives Hadron Energy greater in-house expertise across the principal disciplines involved in developing a nuclear reactor for production. Combining component design, mechanical systems engineering and structural integrity analysis within the same organization can help coordinate technical decisions and address design challenges earlier in development.
The team will also work with nuclear suppliers and fabricators to support the transition from engineering specifications to manufactured components. This is particularly relevant to Hadron’s objective of developing a microreactor designed for factory production, where component standardization, manufacturing coordination and repeatable quality processes are important considerations.
The company’s licensing strategy will require detailed engineering evidence demonstrating that the reactor design and its components meet applicable safety and regulatory requirements. Experience with ASME nuclear codes and regulatory reviews can help inform the preparation of technical documentation and support engagement with relevant authorities.
However, the appointments alone do not establish a licensing timeline or confirm when the Halo reactor will enter commercial operation. Those milestones will depend on continued design development, regulatory review, supply chain readiness, manufacturing and other deployment requirements.
Supporting the Future of Micro-Modular Nuclear Power
Hadron Energy’s recruitment announcement comes as the company continues developing its 10-megawatt-electric Halo Micro-Modular Reactor. Microreactor systems are intended to provide compact nuclear power solutions that could serve customers requiring dependable electricity in locations where conventional power infrastructure may be limited or where energy resilience is a priority.
The potential applications of such systems depend on project requirements, regulatory approvals, deployment economics and site-specific considerations. For developers, turning the technology into a commercially viable product requires a combination of reactor engineering, manufacturing expertise, regulatory planning and reliable supply chain execution.
By appointing Kent Olson, Stephen Moore and Dr. Yifan Huang, Hadron Energy is strengthening its capabilities in several engineering areas that directly influence reactor design and manufacturing readiness.
Their experience with established nuclear programs, advanced reactor projects and pressure boundary integrity analysis provides the company with additional technical resources as it works to advance Halo toward licensing and production.
The appointments reinforce Hadron Energy’s focus on building the engineering organization needed to move from reactor development toward physical hardware and eventual deployment. As work progresses, the integration of experienced nuclear engineers, component suppliers and manufacturing processes will be important to the company’s efforts to bring its light-water micro-modular reactor technology to market.
