What We Do

One Team. The Full Reactor Lifecycle.

Software, hardware, and integration under one roof, from first concept to full-power test.

01 · Software

Design & Simulation

Reactor design, coupled multiphysics, criticality safety, and AI-accelerated optimization.

02 · Integration

Model to Hardware

Digital twins, systems integration, prototyping, and separate-effects validation.

03 · Hardware

Fabrication & Test

Precision machining, brazing & welding, and high-temperature, ultra-high-vacuum testing.

Compact space reactor, under 200 kg
The Bridge · Dual-Use Core

One Core. Earth or Orbit.

A single launch-safe core, under 200 kg: silent power for a remote or forward operating site today, a lunar outpost tomorrow. The crossover design at the heart of our portfolio.

Reactor Portfolio

Three Families.
Nine Designs.
One Platform.

Nine configurations built from a few shared cores: Terrestrial, Dual-Use, and Space. The same compact core that powers a forward base can power a lunar outpost.

The Brains Behind the Nation's Reactors

We don't just propose reactors. Our team has authored U.S. government reference designs and taken reactor hardware to full power, across the agencies that lead American nuclear.
