For any energy source to make a worthwhile difference in decarbonizing the global economy, it has to be the most affordable option. Our design is driven by economics and market requirements to achieve scalable implementation.

Key insights that have influenced the technical parameters include:

  • Cost is driven by speed of construction, irrespective of reactor technology

  • Using the standardized industrial supply chain de-risks licensing, skills, materials 

  • 100 MWe fits within infrastructure constraints of most existing electricity markets 


OPEN100 replicates key aspects of the most successful past nuclear deployments and right-sizes these designs to match these parameters without adding any complexity. Below you will find a detailed economics and comparison to standard PWR finances.
