Built on Proven Engineering, Designed for Passive Safety & Scalable for the Future
Kadmos Energy designs and engineers scalable nuclear reactors that rely on passive safety, natural circulation, and proven components. Our “Home Depot” approach minimizes bespoke R&D and licensing risk by integrating off-the-shelf technologies into an integral, simplified plant— optimized for high availability and rapid deployment.
Why Kadmos
Pragmatic answers to nuclear's hardest bottlenecks
Solving the Capital Valley of Death
Modular units in the few-hundred-million range reduce front-loaded capital and open more financing pathways.
Solving the Regulatory Gauntlet
Proven materials and technologies with minimal R&D streamline the licensing basis.
From Simulation to Steel
No exotic materials: we integrate well-characterized components into a manufacturable system.
Rebuilding the Supply Chain
First-principles design avoids specialized nuclear-only parts wherever possible.
Deployment Timelines
Off-the-shelf components dramatically shorten lead times from order to operation.
KADMOS Design
KADMOS Design: engineered for high availability
- Integral primary system with components embedded in the vessel
- Operation at set-point by natural circulation (passive operation / passive safety)
- Standard PWR fuel for supply-chain strength
- Boiling in the reactor chimney—no external steam generators or separate pressurizer
- Small booster pump only for set-point approach and load-follow
- Reactor vessel submerged in an underground pool for inherent grace time
- Quick-opening pressure-boundary concept (e.g., clamp-ring) to minimize outage time
