Company Profile

Aalo Atomics, headquartered in Austin, Texas, is developing the Aalo-X — a sodium fast reactor competing in the DOE Reactor Pilot Program targeting criticality at Idaho National Laboratory by July 4, 2026. The company received PDSA approval for the Aalo-X in 2025, authorizing sodium fast reactor construction at INL. Unlike several competitors, Aalo uses standard low-enriched uranium rather than HALEU — significantly de-risking their fuel supply chain and avoiding dependency on the constrained HALEU supply market. The Aalo-X is targeting the data center and industrial power market with a compact, modular fast reactor design.

Reactor Specs

REACTOR DESIGN

Aalo-X · Sodium Fast Reactor

Uses liquid sodium metal as coolant instead of water. Operates at higher temperature for greater thermal efficiency.

POWER OUTPUT

10 MWe

Powers ~8,130 average US homes. A standard large nuclear plant produces ~1,000 MWe.

COOLANT

Liquid Sodium

Enables atmospheric pressure operation. If cooling fails, the reactor naturally shuts down without operator action or external power.

FUEL TYPE

Low-enriched UO₂

Standard uranium dioxide ceramic pellets. Used in virtually every operating commercial reactor. Well-understood supply chain.

TARGET OPERATION

2026

US nuclear projects historically require 7–10 years from construction permit to first power. The 2026 target assumes factory-built modular components and no major regulatory delays.

SITE LOCATION

Idaho National Laboratory, ID

Adjacent to Idaho National Laboratory — the DOE's primary nuclear energy research facility. Site has hosted test reactors since the 1950s.
