Aalo AtomicsIn Development
A factory-mass-manufactured 10 MWe (30 MWt) sodium-cooled, graphite-moderated reactor running on low-enriched uranium-dioxide fuel at near-atmospheric pressure. Sized to ship by truck, with fully passive shutdown and 72+ hour passive decay-heat removal; five Aalo-1s power each Aalo Pod.

Full-scale core design demonstrated criticality in the Aalo-X Critical Test Reactor at INL on July 4, 2026; commercial units will deploy in 50 MWe Aalo Pods.

Announced next steps from Aalo Atomics that mention Aalo-1.
2027
File Aalo's first commercial reactor license application with the Nuclear Regulatory Commission, a combined construction and operating license covering the planned commercial Aalo-1 fleet (including the seven-reactor Idaho Falls Power project under an existing MOU). The 2026 COLA target has slipped: Aalo's public homepage now says the regulatory application for the first commercial Aalo Pod will be submitted in 2027. The NRC docket remained in pre-application as of August 2026, with a Regulatory Engagement Plan on file since 2024 and no COLA submitted.
04
Cloud provider Crusoe and reactor startup Aalo Atomics announced a strategic partnership on July 30 to deploy what they call the first nuclear-powered AI data center. A 2027 proof-of-concept at Idaho National Laboratory will pair a 50 MWe Aalo Pod (five sodium-cooled Aalo-1 microreactors) with a Crusoe Spark modular data center running Crusoe Cloud, with both companies targeting commercial deployments by the end of 2029.
05
Aalo's extra-modular power plant for AI data centers: five Aalo-1 reactors sharing multiple turbines (the company site specifies three) producing 50 MWe. Built from factory-manufactured truck-sized modules, designed to install in months and to phase maintenance so the plant is never fully offline.
Aalo's experimental reactor campus at Idaho National Laboratory, built under the DOE Reactor Pilot Program. Its sodium-cooled Critical Test Reactor - a full-scale Aalo-1 core with 13 uranium-dioxide fuel assemblies - reached first criticality on July 4, 2026; the campus's follow-on Project Ascension reactor is intended to generate 10 MWe and power a co-located experimental data center.
