The space nuclear power bottleneck — and how to fix it
This analysis identifies bottlenecks constraining spacecraft nuclear power — limited production of reactors and radioisotope sources, constrained test facilities, and regulatory hurdles — and proposes steps to expand manufacturing, testing and licensing. Accelerating these fixes is framed as essential to enable high‑power satellites, nuclear propulsion and future deep‑space missions.
