Hadron Energy, Inc. announced the publication of its first U.S. patent application for the integral architecture of the Halo micro-modular reactor.
The disclosure marks a critical step in the company's efforts to deploy small-scale nuclear power. By establishing legal protections for its foundational technical architecture, the company aims to accelerate the development of its nuclear technology platform.
The United States Patent and Trademark Office published the application on May 7, 2026 [1]. The filing, titled “Micro Integral Nuclear Reactor,” is listed under publication number US 2026/0128185 A1 [1]. This document outlines the specific design and structural components that enable the reactor to function as a modular unit.
Hadron Energy, headquartered in Redwood City, California, designed the Halo system to provide consistent, carbon-free electricity [1]. The flagship reactor is rated for 10 megawatt-electric (MWe) [2]. This power capacity is intended to support a variety of deployments, ranging from remote industrial sites to smaller community grids.
The company's strategy focuses on the "integral" nature of the architecture, which typically means combining multiple reactor components into a single vessel to reduce complexity and increase safety. This approach is central to the goal of providing 24/7 power without the need for massive infrastructure overhauls associated with traditional large-scale nuclear plants [2].
While the patent application is now public, the company continues to develop the hardware required to bring the 10 MWe system to market [2]. The publication of the patent is a standard part of the intellectual property process, allowing the company to claim ownership of the specific engineering methods used in the Halo design [1].
“The flagship reactor is rated for 10 megawatt-electric (MWe).”
The shift toward micro-modular reactors represents a move away from the massive, centralized nuclear plants of the 20th century. By securing patents for a 10 MWe system, Hadron Energy is positioning itself to compete in the emerging market for decentralized energy, which is increasingly attractive for military bases, remote mining operations, and regions with unstable power grids.
