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 - 300 kWe
