Ahead of Hadron Energy beginning trading on Nasdaq under the ticker $HDRN on May 26th, we wanted to share a glimpse of Hadron’s vision building the future of microreactors. Hadron Energy is developing the Halo Micro Modular Reactor (MMR), a compact, factory-built light-water reactor designed to deliver reliable, carbon-free power for AI data centers, industrial sites, remote communities, military applications, and critical infrastructure. Each Hadron MMR is designed to generate 10 MWe of reliable power and is transportable by truck or rail to support flexible deployment where power is needed most. By generating power directly on-site, Hadron’s microreactors may reduce reliance on extensive transmission and distribution infrastructure. Multiple units can be deployed in a modular format to meet growing demand, with a targeted fuel-cycle of 10 years and an intended 50-year useful life. Hadron’s microreactors leverage proven light-water technology which powers ~90% of the global nuclear power fleet today. The Nuclear Regulatory Commission (NRC) is most familiar with light-water designs, they have ~27,000 cumulative reactor years of operational history, and light-water avoids the risks associated with novel fuels or coolants. Hadron’s microreactors are designed with inherent and passive safety features and are installed below grade to maximize protection of the public and the environment. 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 through slightly higher enrichment. Because LEU+ remains within the existing regulatory framework, may support a more familiar licensing pathway relative to certain advanced reactor technologies. Most importantly, LEU+ leverages existing portions of the domestic light-water reactor fuel supply chain, which we believe may reduce fuel supply constraints relative to certain advanced reactor approaches dependent on HALEU or TRISO fuel. Our approach focuses on regulatory efficiency and standardized deployment. In October 2025, the NRC accepted Hadron’s Quality Assurance Program Description (QAPD) Topical Report for review, an important step in establishing the company’s regulatory foundation. Hadron maintains active engagement with the NRC through a dual-track pathway, pursuing both Manufacturing and Combined Licenses, while monitoring evolving NRC initiatives intended to support standardized deployment and serial manufacturing approaches for advanced reactors. Hadron’s leadership team brings decades of experience across nuclear plant operations, NRC licensing, reactor engineering, fuel design, and quality assurance, supported by engineers focused on moving from design through deployment efficiently. As electricity demand continues to accelerate globally, particularly across AI infrastructure and industrial applications, Hadron is targeting a growing market expected to exceed $7 billion by 2030, according to Grand View Research. We believe light-water reactors continuing to produce reliable, 24/7 power, will play a critical role in the future of energy and national security.
