Kilowatt-Scale Special Purpose Reactor

01

Shielding

Built-in tungsten, titanium carbide, and boron carbide minimize exclusion zone and increase the speed of deployment

02

Heat Transfer

Sodium heat pipes provide passive and redundant heat removal without moving parts to maximize reliability

03

Reactivity Controls

Automated control drums and boron carbide shutdown rod developed from space reactor control systems

04

Core

Combination of HALEU TRISO and graphite moderator and reflector is high technology readiness, well-characterized, and maximizes safety

Resilient

TRISO encapsulates every fuel particle in silicon carbide. Sodium heat pipes provide redundant, self-contained heat transfer from the core.

Passively safe

Highly Automated

Continuous energy with no sustaining supply chain for 3 years. Automated controls, power management, and distribution with no specialized workforce.

3+ year autonomous operation

Reliable

Low-pressure nitrogen closed Brayton cycle maximizes reliability and minimizes maintenance for deployment anywhere.

100+ kWe
