Halo Micro-Modular Reactor (MMR)

planned

Hadron Energy, Inc. is developing the 10-megawatt electric (10MWe) Halo Micro-Modular Reactor (MMR), a factory-manufactured, transportable light-water reactor designed to deliver continuous, emission-free baseload power and heat with a multi-year refueling cycle. The reactor targets commercial deployment in 2032, leveraging centralized manufacturing for scalable, reliable, and rapid deployment to serve data centers, military bases, heavy industry, and other markets. It uses proven light-water reactor technology, enabling a predictable regulatory pathway with the U.S. Nuclear Regulatory Commission. The 10MWe modular units can be clustered to meet high power demands and deliver process heat up to 300 degrees Celsius for various industrial applications, with a planned 60-year service life featuring streamlined decommissioning and replacement.
