Aalo Atomics

We build mass-manufactured nuclear plants designed to power anything from a data center to a city - eventually achieving 3¢/kWh electricity.

The foundation of our sodium testing program. The STL circulates sodium reliably with in-house design, manufacturing, and test programs. Its small-scale components provide baseline flow, temperature, and quality data for Aalo-0 and Aalo-X. Operational in our skunkworks lab in Idaho today.

The CTR is a zero-power reactor built at Idaho National Laboratory. It enables us to validate core neutronics, test control rod mechanisms, and implement a lifecycle build and licensing process for a nuclear facility at full-scale. On July 3, 2026, in the CTR, we achieved initial criticality: a self-sustaining nuclear reaction.

Most nuclear companies are design firms. We treat the factory as the product. The 10% we don't make comes from a supplier network in the US. No unobtainium, nothing on critical path that we don't control.

We are looking for partners who can also deliver NQA-1 components. Reach out to our Procurement Specialists to learn more.

If we’re successful, humanity will benefit. If we fail, humanity will be worse off. Every day counts.

We won’t be successful unless we earn the public's trust. Operating with openness is critical.

Nuclear is controversial. Don’t dismiss fear as meaningless. Educate people on the true risks, and show them what we’re doing about it.

Liquid sodium carries heat one hundred times better than water. That means our reactor vessels are two-to-five times smaller than the competition's at the same power level - small enough to fit on a normal truck, which is what makes mass manufacturing possible. Sodium also runs at near-atmospheric pressure, which means simpler systems and inherent passive safety. The reactor stays safe even when nobody is watching it.

We weld our own vessels. We build our own scaffolding modules. We fabricate our own fuel assemblies. We write our own control systems. The 10% we don't make comes from a 127-supplier network we built across the United States - no unobtainium, nothing critical on a path we don't control.

We built the first new reactor facility at Idaho National Laboratory in fifty years - in thirty-six days. The Critical Test Reactor was assembled in under four weeks. Factory completed and NQA-1 certified in six months. All achieved with under $100m in spend, in under 3 years.
