What Aalo Atomics does
Aalo Atomics is a privately held, venture-backed advanced nuclear startup founded in 2023 and headquartered in Austin, Texas, with operations in Idaho Falls, Idaho. The company designs and manufactures factory-built, sodium-cooled, graphite-moderated, thermal-spectrum extra-modular reactors (XMRs) using low-enriched uranium (LEU, ≤5% U-235) UO2 fuel. Its product roadmap progresses from Aalo-0 (a full-scale non-nuclear prototype containing 40,000 lbs of liquid sodium) to the Aalo-X Critical Test Reactor (zero-power physics validation) to Aalo-X (a 10 MWe / 30 MWth experimental power plant under construction at Idaho National Laboratory, targeting criticality by July 4, 2026 under the DOE Reactor Pilot Program) to the Aalo Pod (the planned 50 MWe commercial product, configured as five 10 MWe reactor modules paired with one turbine and packaged into road-transportable factory-built modules for co-location with AI data centers).
Aalo's core technology leverages liquid sodium's high thermal conductivity to extract up to 10x more energy per unit physical size than water- or gas-cooled nuclear systems, while atmospheric-pressure operation enables passive safety features including 72 hours of unpowered decay heat removal. The company vertically integrates reactor design, module fabrication in a 40,000 sqft Austin pilot factory, reactivity control systems, and operator training — supported by tier-1 partnerships with Baker Hughes (steam turbines), Flowserve (pumps/valves), Urenco (UF6 enrichment), Global Nuclear Fuel (LEU fuel rods), Paragon (I&C), Siemens, and DuBose. It has also deployed Microsoft Generative AI for Permitting and NVIDIA digital-twin tooling, reporting a 92% reduction in permitting time and ~$80M in estimated annual savings.
Aalo is pre-revenue and targets AI hyperscalers, data center operators, and utilities as customers, with its first commercial fleet MOU (seven Aalo-1 reactors) signed with Idaho Falls Power and a partnership with Texas A&M University for 1 GW of data-center power. The company has raised approximately $136M across a $6.26M seed (Fifty Years-led, 2023), a $27M Series A (Earth Venture Capital participating, 2024), a $100M Series B (Valor Equity Partners-led, Aug 2025), and an additional ~$2.58M raise disclosed in October 2025. The long-term commercial model is hardware sales of Aalo Pods combined with electricity generation under long-term PPA-style offtake contracts.

Revenue model
- Hardware sales of Aalo Pods (commercial reactor units): Aalo's primary future revenue stream will be the sale of 50 MWe Aalo Pod commercial nuclear plants to enterprise customers such as data center operators and utilities. Pre-revenue at present; targeting first commercial Aalo Pod deployment later this decade.
- Power generation / long-term energy offtake: Future revenue is expected to include electricity generation sold via power purchase agreements (PPAs) or similar long-term offtake contracts with utilities and hyperscalers, exemplified by the MOU with Idaho Falls Power for seven Aalo-1 reactors and the planned co-located data center with Aalo-X at Idaho National Laboratory.
- Pre-revenue / venture-funded development: Aalo is currently pre-revenue, funded by venture capital (Seed $6.26M, Series A $27–30M, Series B $100M, total ~$136M) and DOE OTA agreements, with first revenue-generating commercial deployment planned later this decade.

Aalo Atomics product offering
Product offeringCore offering
Aalo Atomics designs, manufactures, and sells factory-built, sodium-cooled, graphite-moderated extra-modular nuclear reactors (XMRs) packaged as the 50 MWe Aalo Pod (five 10 MWe reactor modules plus one turbine) for behind-the-meter power at AI data centers and utility-scale baseload. Its commercial product roadmap runs from the Aalo-0 non-nuclear sodium prototype, through the Aalo-X Critical Test Reactor and 10 MWe Aalo-X experimental power plant at Idaho National Laboratory, to the Aalo Pod commercial unit, with a long-term cost target of less than 3¢/kWh enabled by factory mass production.
Product overview
Aalo Atomics sells a single integrated product line of factory-built sodium-cooled nuclear plants (XMRs) purpose-built for AI data centers, organized as a staged platform-plus-modules architecture rather than a single reactor: Aalo-0 is the full-scale non-nuclear sodium prototype that de-risks thermal-hydraulics, the Aalo-X Critical Test Reactor (CTR) validates core physics at zero power, Aalo-X is the 10 MWe experimental power plant at Idaho National Laboratory targeting criticality by July 4, 2026, the Aalo-1 reactor is the production 10 MW unit cell proven through Aalo-X, and the Aalo Pod is the 50 MWe commercial product (five Aalo-1 reactors plus one turbine) packaged into transportable modules. Underlying these products are Aalo's reactor design software, vertical integration in its Austin factory, DOE-authorization regulatory pathway, and a Microsoft-NVIDIA AI-for-nuclear ecosystem used for permitting, design, and operations.

Aalo Atomics competitors and assessment
Company assessmentDirect peers
- Oklo: Oklo is developing sodium-cooled fast reactors (Aurora) and went public via SPAC in 2024. It is the most directly comparable peer: same sodium reactor lineage, similar data-center customer focus, and a fellow DOE Reactor Pilot Program selectee.
- TerraPower: Bill Gates-backed TerraPower is building the Natrium sodium-cooled fast reactor in Kemmerer, Wyoming, in partnership with GE Hitachi. It is a direct competitor in sodium-cooled reactor technology and is targeting data-center and industrial customers at much larger scale.
- X-energy: X-energy is developing the Xe-100 high-temperature gas-cooled reactor with Dow and others, and is one of the leading advanced reactor companies. It competes for the same hyperscaler and industrial clean-firm-power customers as Aalo.
- Kairos Power: Kairos Power is building fluoride-salt-cooled high-temperature reactors (Hermes) at Oak Ridge and is pursuing Google as a hyperscaler customer. It is a fellow advanced reactor competitor targeting data center loads.
- Terrestrial Energy: Terrestrial Energy is developing the Integral Molten Salt Reactor (IMSR) and is pursuing NRC and CNSC licensing. It competes in advanced, non-light-water reactor designs targeting industrial and data center customers.
- Last Energy: Last Energy is developing small modular pressurized water reactors for private customers in Europe and the U.S., with a similar factory-built, behind-the-meter data center thesis. It is a peer in business model even though its reactor technology is light-water rather than sodium.
- Radiant Nuclear: Radiant is developing a high-temperature gas-cooled microreactor (Kaleidos) and is a fellow DOE Reactor Pilot Program selectee. It overlaps with Aalo on small, modular, data-center-tilted reactor offerings.
Broad incumbents
- NuScale Power: NuScale is the only publicly listed SMR company with NRC-certified light-water reactor designs. It is a broader incumbent in the small modular reactor category and competes for utility and data center buyers, although it does not share Aalo's sodium technology or factory-only ethos.
- Westinghouse Electric Company: Westinghouse is a global incumbent in commercial nuclear, supplying AP1000 reactors, fuel, and services. It is a broader incumbent that competes for utility-grade nuclear customers and is developing its own eVinci microreactor, which overlaps with Aalo's smaller-scale offerings.
Emerging players
- Valar Atomics: Valar Atomics is an early-stage advanced reactor startup and a fellow DOE Reactor Pilot Program selectee. It is an emerging competitor with partial overlap in target customers (data centers, defense) but with limited public technology and funding detail relative to Aalo.
