The BWRX-300 is a next-generation small modular reactor designed to deliver clean, reliable and affordable energy at scale. With zero CO₂ emissions, full dispatchability and a footprint no larger than a football pitch, it represents a new standard for modern nuclear infrastructure.
Built on decades of operating experience and designed for industrial deployment, the BWRX-300 combines world-class safety, simplified construction and competitive economics, creating a reactor that is not only advanced, but investable – and this is exactly why we chose it.
We see the BWRX-300 as a source of clean energy that can be delivered at any time, in any weather, from a compact facility capable of supplying stable baseload power to modern economies.
With zero carbon emissions, high availability and full weather independence, the BWRX-300 provides a cornerstone for energy security and industrial competitiveness.
The BWRX-300 is the tenth evolution of the Boiling Water Reactor, the result of nearly 70 years of reactor development by GE Hitachi Nuclear Energy and operational experience from more than 60 operating BWR units worldwide.
It is a 300 MWe water-cooled, natural circulation small modular reactor with passive safety systems, leveraging the licensed design basis of the U.S. NRC-certified ESBWR.
This heritage delivers a rare combination: next-generation performance built on fully proven technology.
Through radical design simplification and the use of proven components, fuel design and established supply chains, the BWRX-300 has been engineered to minimize complexity, reduce risk, and accelerate delivery.
As a “smart reactor”, it relies on natural circulation and passive cooling systems, enabling stable, simple and inherently safe operating cycles, without the need for active systems or operator intervention in emergency conditions.
