The US now has three microreactors running – and data centers are watching closely

The Nuclear Leap: Three Microreactors Power Data Centers

The future of energy, once confined to theoretical physics, is rapidly becoming a tangible reality. A significant milestone has been achieved in the quest for advanced nuclear technology, with three independent microreactors now successfully running data centers, marking a major step in accelerating Department of Energy research.

This breakthrough demonstrates that small, contained nuclear systems are moving from the laboratory into practical application. The success involves advanced concepts for safely harnessing nuclear energy on a smaller scale, promising a cleaner and more accessible power source.

Leading this charge are several pioneering projects. Unity, a microreactor developed by Houston-based Deployable Energy, is the most recent to reach criticality. This achievement solidifies Unity‘s role in pushing the boundaries of deployable nuclear technology.

Joining Unity are two other remarkable reactors that cleared this critical hurdle in June: Antares, a reactor based in Torrance, and Valar Atomics, located in El Segundo. Together, these three facilities represent a significant progression in demonstrating the viability of advanced nuclear designs for commercial use.

This coordinated effort by the Department of Energy highlights a determined push to accelerate complex scientific demonstrations. It signals an exciting shift toward harnessing advanced nuclear technologies not just for theoretical research, but for real-world applications like powering essential data centers.

The achievement underscores the potential of microreactor technology: compact, safe, and scalable solutions that can contribute to both energy independence and technological advancement. As these reactors operate, they provide compelling evidence that advanced nuclear demonstrations are poised to deliver transformative benefits for the energy sector.
