Demand for clean, reliable power is rising faster than almost anyone predicted, and a microreactor only helps if it arrives in time to matter. Data centers that never sleep. Factories that run around the clock. Remote sites far from any major grid. Communities that need power that doesn't flicker. These are essential needs that are here right now, not in some distant future. The $HDRN Halo is a microreactor built on proven light water technology: compact enough to site directly where the power is used, reliable enough to run day and night regardless of weather, and clean enough to meet the moment. youtube.com/watch?v=rK_M8AYb…

$HDRN's nuclear energy technology builds on 70 years of operating data, decades of proven engineering, and an existing, qualified nuclear workforce and supply chain. Hadron didn’t reinvent the reactor. We took what works and we made it micro, modular, and ready to deploy.

$HDRN’s Halo MMR builds on decades of proven light-water reactor operating experience. Designed with five layers of safety, from the outer containment structure to the fuel coating, Halo is engineered to be walk-away-safe and community friendly. The future of modular nuclear energy is distributed and behind the meter.

Big news for @hadron_energy: former TerraPower COO Eric Williams is joining us as Executive Vice President of Engineering. Eric brings nearly 30 years of advanced nuclear and FOAK reactor experience, including helping lead TerraPower through NRC approval of the Natrium Construction Permit. He previously served as Head of Engineering and Design Authority for the 345 MWe Natrium Demonstration Project and helped scale TerraPower’s engineering organization from 60 to 180 engineers. Eric will now lead Hadron’s design engineering organization as we accelerate the Halo Micro-Modular Reactor toward commercialization. We’re building the team to bring Halo to market.

Two years after founding @hadron_energy, I had the honor of ringing the @Nasdaq Closing Bell. Hadron is the first publicly traded company focused on light-water microreactor technology. That's a milestone I'll never forget. It was incredible to celebrate with our investors, partners, suppliers, friends, family, and the outstanding Nasdaq team. Thank you to everyone who has supported Hadron's journey and helped make this possible. At Hadron, we are building Halo, a factory-built, 10 MWe light-water microreactor designed to deliver reliable, carbon-free power where it's needed most: AI data centers Critical infrastructure Military installations Industrial facilities Remote communities We believe resilient, distributed nuclear energy will play a defining role in powering the next generation of American infrastructure. None of this would be possible without our extraordinary team. I'm incredibly proud of what we have built together, and we're just getting started. We are actively hiring exceptional engineers who want to help shape the future of nuclear energy. America's demand for abundant, reliable energy has never been greater. Nuclear power will be essential to meeting that challenge. The opportunity ahead is extraordinary and the best is yet to come.
