Hadron Energy (HDRN) showcases Halo-10 micro‑modular reactor concept and fuel cycle vision
Rhea-AI Filing Summary
Hadron Energy, Inc. furnished an investor presentation alongside an 8-K describing its Halo-10 light‑water micro‑modular reactor, positioned to meet rising electricity demand and growing support for nuclear power. The company highlights U.S. grid trends, noting falling coal use, flat nuclear output, and rising wind and solar generation.
The Halo-10 concept targets a 10MW modular reactor that uses existing pressurized water reactor technology, extended fuel cycles, and improved power flattening to reduce outages and maintenance. The design emphasizes established safety principles, including defense-in-depth and features intended to achieve stable shutdown without operator intervention, as well as air-cooled condensers that reduce dependence on water. The presentation also discusses HALEU and LEU+ fuel cycle challenges, spent fuel volumes, and potential reprocessing approaches.

Problem For the first time in ~45 years, public support for nuclear power is producing growth. Demand for energy grows even faster. Can we rise to the challenge? https://www.pewresearch.org/short-reads/2025/10/16/support-for-expanding-nuclear-power-is-up-in-both-parties-since-2020/
The DATA Electricity Generation Percent By Source In The USA Regardless of opinions, what has actually changed in US? The last five years show three main trends: Coal use in the US continues to decrease Total energy generated with nuclear decreased Wind & Solar power have increased 2020 2025 www.eia.gov
What nuclear offers Nuclear must provide what Solar & Wind cannot Solar / Wind AI usage cares not for using only Wind / Solar 91% Nuclear power generation has a consistent and high availability Nuclear Nuclear in place of natural gas has an even bigger impact now 24% / 34% Solar / wind capacity factors are no longer increasing
Nucear MUST DELIVER Nuclear fosters public confidence as our reactors operate quietly, consistently, and efficiently. Nuclear wins new support by reducing our historical reliance on water cooling; water availability is becoming contentious. As momentum builds, Nuclear support technology expansion where appropriate. Safety Innovation, Engineering, Regulation, Manufacturing all combine to further increase safety Reliability Demonstrating our new technologies provide electricity consistent with current nuclear generation Adaptability Meet the needs of diverse off-takers in a variety of locations and climates
Change CAN BE good Meeting the Market Needs Customers Fitting reactor size with demand AP-1000* and BWRX-300** are well suited to densely populated grids, but too big for many communities. Licensing Pathway to approval and operation Work with the NRC and DOE to deploy reactor technologies quickly. Timeline Nuclear projects are not known to be on time Increase the accuracy of development and deployment timelines, even if they are longer. Accuracy should be the goal. Costs Capital cost, construction, operation Increasing capital costs cannot be supported by all possible off-takers. Increased preferences for PPA agreements are justified. The Westinghouse Electric AP-1000* and the General Electric BWRX-300**
Existing Technology Accessible LEU+ Supply Qualified PWR Fuel Design Existing Supply Chain with many ASME Section III vendors Deep PWR operating experience, with +20,000 reactor-years Intentional Design Choices Fewer parts where possible Selecting “off-the-shelf” components with considerable operating data Early vendor feedback, reducing manufacturing challenges Selective design risks that improve safety or reduce licensing burden THE Near-Term Solution
Established safety Defense-In-Depth The idea has been developed over the years, improved, and tested. More recent innovations have addressed challenges encountered during Fukushima. The design of Halo-10 is intended to achieve stable shutdown condition without operators or external intervention.
The nuclear Fuel Modular Scalability Our 10MW requires a fraction of the land compared to wind and solar, making if the most space-efficient path to reliable decarbonization Extended Fuel Cycle Better flux control means reduced localized burnup, enabling longer fuel cycles and fewer outages for refueling Improved Power Flattening Strategic placement of burnable poisons int the 15x15 arrays smooths out excessive reactivity, keeping power distribution even across the core Enhanced Reactor Behavior Less aggressive reactor operation reduces wear and tear on the system, allows finer control, and reduces maintenance
Available water to remove heat from the reactor is of critical importance Halo-10 units are designed to reduce loss of coolant accident impacts and the vault pool contains additional inventory if needed Additional Safety
Site-Agnostic Air Cooled condensers need no water Interface with small or large grids, or it can be deployed behind-the-meter Multiple smaller units reduces the impact of maintenance or refueling
Industry Success A wide variety of nuclear technologies are needed to fulfill long-term energy needs The Halo-10 is designed to meet the near-term needs using existing technologies. As non-LWR technologies accumulate fleet-level operating experience, they can and will fill the long-term needs www.wordclouds.com
Avoiding a history repeat Spent LWR Fuel ~280,000 tons Spent LEU+ Fuel The new methods to process LEU fuel should apply here ~1000 tons There are LTAs presently being depleted in the USA. Includes naval & gov. sources. Spent HALEU Fuel A variety of fuel forms, but some have processing technology ~1000 tons Very few reactors operated at this enrichment. This problem was supposed to be solved several times. About 30% of the original 400,000 tons has been reprocessed An Industry Challenge https://world-nuclear.org/information-library/nuclear-fuel-cycle/fuel-recycling/processing-of-used-nuclear-fuel https://world-nuclear.org/information-library/nuclear-fuel-cycle/conversion-enrichment-and-fabrication/high-assay-low-enriched-uranium-haleu
Challenges Advantages HALEU & LEU+ Spent Fuel Elevated burnup produces higher decay heat loads Few if any commercial spent fuel casks Limited decay heat curves for LEU+ and HALEU enrichment levels Residual U-235 available for reprocessing Fuel Processing innovations available for various fuel types Wider fleet using LEU+/HALEU, more material available “Re-use” demonstrated with the DUPIC program Practical needs
