How We Build Reactors

One Company. The Whole Reactor Stack.

You can't build a reactor without all three: simulation, materials, and hardware. We own the entire stack in-house, from first concept to full-power test.

01 · Software

Simulation & Design

CRISP, our in-house platform: coupled multiphysics, criticality safety, and AI-accelerated design search across every reactor type.

02 · Materials

Materials & Fuels

Advanced materials, fuels, and moderators engineered in-house to make the core lighter, tougher, and transport-ready.

03 · Hardware

Fabrication & Test

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

Compact space reactor
The Bridge · Dual-Use Core

One Core. Earth or Orbit.

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

Reactor Portfolio

One Platform.
Every Mission.

Ten-plus designs built from one shared foundation of materials, fuels, and modules, with more than twenty-five in house. The same compact core that powers a forward base can power a lunar outpost.

Signature Platform

CRISP: Model a Reactor End-to-End

Couples 30+ physics from material data to accident, launch, and transport in one automated pass. Real, benchmarked solvers and convergence-checked results, not slideware.

The Brains Behind First-of-a-Kind Reactors

We don't just propose reactors. Our team authors first-of-a-kind designs and takes new-physics hardware to full power, on the programs that set the pace for advanced nuclear.
