Old technology redesigned for Global commercial market (RHU & RTG)


Stellar Nuclear develops compact, maintenance-free and cold-tolerant RHU and RPS modules that keep instruments, sensors and critical electronics alive in extreme environments where solar power is limited or unavailable. Based on small RHU modules, our systems can be combined into larger mission-specific architectures and supported by advanced alloy cladding, SiC/SiC fibre-composite heat and impact protection, additive manufacturing, radiators and lightweight shielding, including metal foams.
Our goal is to build a safe, reliable and scalable European supply chain for space nuclear heat and power systems.
