Aalo Atomics Secures $100 Million in Series B Funding, Unveils Non-Nuclear Reactor Prototype for AI Data Centers

Aalo Atomics, an Austin-based company specializing in modular nuclear plants, has secured $100 million in Series B funding, bringing its total raised capital to over $136 million. This significant investment coincides with the recent unveiling of the first full-scale, non-nuclear prototype of its Aalo-1 reactor, signaling a critical step towards powering the rapidly expanding energy demands of artificial intelligence (AI) data centers. As CEO Matt Loszak stated in a recent feature by Arena Magazine, "Every advanced reactor company talks about changing the world. We're the ones actually building."

The Aalo-1 reactor forms the core of the company's Aalo Pod XMR, a 50 MWe power plant purpose-built for data centers. Each Aalo Pod is designed to be fully modular, containing five 10 MWe Aalo-1 reactors, and can seamlessly scale to gigawatt capacities. These reactors utilize a liquid sodium metal design for efficient heat extraction and operate with readily available low-enriched uranium fuel (LEU+), aiming to produce electricity at a competitive $0.03/kWh.

Aalo Atomics' technology addresses the surging power requirements of AI infrastructure, a challenge that has prompted major tech companies like Microsoft, Google, and Amazon to explore nuclear energy solutions. The Aalo Pod's small physical footprint and independence from external water sources facilitate easy co-location with data centers, while mass manufacturing and standard shipping methods are expected to significantly reduce installation times. Loszak emphasized this approach, stating, "We are aiming to do for nuclear reactors what Henry Ford did for cars."

The $100 million Series B funding round was led by Valor Equity Partners, with participation from a diverse group of new and existing investors. This capital will enable Aalo Atomics to double its workforce from approximately 60 to over 120 employees, focusing on acquiring top-tier engineering and manufacturing talent. The company also plans to advance its Aalo-X pilot program, an experimental extra modular nuclear reactor, targeting criticality by July 2026 at the Idaho National Laboratory (INL) under the U.S. Department of Energy’s Nuclear Reactor Pilot Program.

Beyond the prototype and funding, Aalo Atomics has achieved several key milestones, including selection as a partner to develop up to 1 GW of nuclear energy capacity at the Texas A&M Rellis Campus. The company has also signed a Memorandum of Understanding with Idaho Falls Power for the deployment of seven factory-built Aalo-1 reactors, totaling 75 MW of power generation. These developments underscore Aalo Atomics' rapid progress in bringing its innovative nuclear energy solutions to market.
