Startup Series: Nuclear Micro-Reactors with Radiant

Radiant develops portable, one-megawatt nuclear micro-reactors designed to replace carbon-intensive diesel generators in remote or off-grid locations. These shipping-container-sized units utilize high-temperature gas-cooled reactor technology, incorporating passive safety features that allow for natural cooling without complex mechanical systems. By centralizing the refueling process at a factory, the company eliminates the need for customers to manage nuclear waste on-site. These reactors provide a resilient, emission-free power solution for critical infrastructure, including disaster relief efforts and military installations. While the company navigates complex NRC licensing processes and domestic HALEU fuel supply chain constraints, the primary objective remains the mass production of standardized units to deliver reliable, clean energy in environments where traditional grid infrastructure is unavailable.
