Shortening the nuclear development cycle from decades to years
Sep 24, 2025
In this discussion, Mike Laufer, co-founder and CEO of Kairos Power, sheds light on innovative approaches to nuclear reactor design. He advocates for a shift to non-nuclear demonstrations, allowing rapid iteration and cost reductions. Laufer outlines their unique reactor model combining TRISO fuel and molten salt, addressing engineering challenges head-on. He shares insights on building in-house capabilities, responding to technical setbacks, and their game-changing contract model with the DOE, paving the way for partnerships with giants like TVA and Google.

Episode notes
Iterate Non‑Nuclear First To Cut Cost
- Kairos centers cost reduction by iterating quickly and learning from non-nuclear systems first.
- Rapid non-nuclear cycles reveal manufacturing and integration issues long before nuclear licensing becomes critical.
TRISO Plus Salt Adds Passive Barriers
- Kairos combined TRISO fuel concepts with molten FLIBE salt cooling, creating layered passive safety barriers.
- Salt acts as a backup containment that reduces scenarios where fuel could be stressed to failure.
Pong Balls To Simulate Fuel Movement
- Early Kairos tests used simple physical mockups like ping‑pong balls to simulate TRISO pebble movement.
- Those low‑fidelity experiments validated iterative methods before heavier investment.
