Frequently Asked Questions

Hadron Energy plans to go public in 2026 through a business combination with GigCapital7 Corp. with a $1.2B valuation. The transaction is expected to provide approximately $200 million in net proceeds to advance reactor design, licensing, and initial commercial deployment.

Following completion, the combined company is expected to trade on a U.S. national exchange under the ticker “HDRN.” Hadron will become the first publicly listed lightwater microreactor company.

Hadron is executing a strategic, de-risked licensing approach, designed for rapid commercialization. In October 2025, the NRC accepted for review Hadron’s Quality Assurance Program Description (QAPD) Topical Report, a critical step in the regulatory foundation. Hadron maintains active engagement with the NRC through a dual-track pathway, pursuing both Manufacturing and Combined Licenses to enable standardized, fleet-scale deployment. Hadron’s competitive advantage lies in regulatory efficiency by using conventional fuel forms and light-water technology, familiar to NRC staff, avoiding the lengthy and expensive fuel qualification studies required of other fuels that are not currently approved by the NRC.  Hadron is also leveraging industry-standard methodologies for fuel handling and transportation, significantly reducing the regulatory uncertainty.  

Hadron is adopting the NRC’s emerging “Nth-of-a-Kind” licensing framework for serial manufacturing, positioning the company to license reactors at scale, rather than as one-off approvals. Through proactive submission of White Papers and Topical Reports addressing fuel strategy, Principal Design Criteria and safety analysis methods, Hadron is targeting an efficient 18-month review cycle for license issuance in 2029 and commercial operations in 2030.

Hadron uses Low Enriched Uranium Plus (LEU+), enriched to approximately 8% U-235. This fuel builds on the same proven uranium fuel used in today’s commercial reactors, while enabling longer operating cycles and efficient power output for microreactor applications.

Because LEU+ remains within the existing regulatory framework, it supports a more streamlined licensing pathway without the need for novel fuel qualification. Hadron reactors are delivered unfueled and loaded on-site in accordance with standard nuclear industry practices.

Yes. Hadron’s microreactors use proven light-water technology with over 70 years of safe operation, avoiding the risks associated with novel fuels or coolants. The reactors are installed below grade with inherent and passive safety features to maximize protection of the public and environment.

Designed to deliver 10 MWe of reliable, carbon-free power, Hadron’s systems are compact, factory-manufactured, and deployable by truck or rail—enabling rapid, flexible deployment. By generating power directly at the point of use, they also reduce reliance on costly transmission infrastructure, improving both efficiency and overall system resilience.

The Hadron Halo^TM is a compact, factory-built light-water reactor that will deliver continuous, carbon-free power for up to 10 years without refueling with a 50-year useful life. It will be the world’s first micro modular light-water nuclear reactor with portability to meet market demands. Each Hadron MMR generates 10 MWe of power and measures 3x12 meters per reactor module. As the reactors are modular in design, assembled in a production facility and then transported via truck or train to a site. Multiple units can be deployed at one site to meet market power needs as they grow.

Hadron engineers have rapidly iterated through many design-analyze-build-test cycles to optimize the core and plant design to be the world’s smallest, most efficient, reliable reactor that provides power in modular units. As Hadron is planning to mass manufacture the MMRs, the costs will dramatically be reduced by the number of reactors produced on the factory assembly line.

Hadron is addressing the rapidly growing demand for reliable, 24/7 clean power driven by AI data centers, industrial infrastructure, and energy-constrained regions. By delivering scalable, on-site microreactors, Hadron targets a multi-billion-dollar market expected to exceed $7 billion by 2030 (Grandview Research), with significant upside as electricity demand continues to accelerate globally.

Hadron’s leadership team brings decades of experience across nuclear plant operations, NRC licensing, reactor and fuel design, and quality assurance. The team includes former regulators and operators alongside engineers who have led advanced reactor programs from concept through licensing. This expertise is complemented by a growing group of high-performing engineers focused on execution, enabling Hadron to move from design to deployment efficiently.

Hadron Energy was founded in July 2024 by Sam Gibson, a mechanical engineer and serial entrepreneur. As Founder and CEO, he leads the company’s $1.2B public listing, regulatory engagement with the NRC, and overall company development across business operations, team growth, and strategic partnerships.

Driven by a mission to deliver reliable, carbon-free power, Sam selected a light-water reactor (LWR) approach for its proven performance, streamlined licensing pathway, and ability to accelerate deployment. He has been recognized as the youngest Founder & CEO to take a company public, a member of Forbes 30 Under 30 (2026), Forbes Technology Council, and the Harvard Business Review Advisory Council.

Hadron’s light-water microreactor design builds on over 70 years of proven nuclear technology, aligning with an established licensing framework and the 94 operating reactors in the U.S. By avoiding exotic fuels and coolants, we reduce technical and regulatory risk while enabling simpler operations. Combined with a “low-consequence” safety profile and a factory-manufactured, scalable approach, Hadron is positioned to deploy clean, reliable power faster and more efficiently than traditional nuclear.

Hadron will achieve this mission by designing and deploying factory-manufactured, light-water microreactors that deliver reliable, carbon-free power directly where it’s needed. By standardizing production and working closely with regulators and customers, we enable rapid, scalable deployment to meet growing energy demand.

Hadron is revolutionizing access to 24/7 resilient power by building 10 MWe light-water micro modular reactors (MMRs) that can be mass manufactured at scale, and transported easily to deliver cost-effective, environmentally safe and sustainable nuclear power to meet the high demand from emerging markets, including: AI data centers, industrial sites, military bases, and remote applications.
