We see BWRX-300 technology as a source of clean energy with zero CO2 emission, that can be delivered at any time, in any weather from a facility not larger than a football pitch. 

It is a proven technology designed by a company with almost 70 years of experience in nuclear industry whose competences have been proven by over 60 operating BWR reactors.

10th generation of BWR

The BWRX-300 is a 300 MWe water-cooled, natural circulation Small Modular Reactor (SMR) with passive safety systems that leverages the design and licensing basis of GEH's U.S. NRC-certified ESBWR. 

Through dramatic and innovative design simplification, the utilization of a licensed and proven fuel design and the incorporation of proven components and supply chain expertise, the BWRX-300 can become the lowest-risk, most cost-competitive and quickest to market SMR. 

As the tenth evolution of the Boiling Water Reactor (BWR), the BWRX-300 represents the simplest, yet most innovative BWR design since GE began developing nuclear reactors in 1955.

BWRX-300 has been designed to have construction and operating costs that are substantially lower than traditional nuclear power generation technologies.

Key Features

  • World-class safety: Steam condensation and gravity allow the BWRX-300 to cool itself for a minimum of seven days without power or operator action
  • Cost competitive: Projected to have up to 60% less capital cost per MW when compared with typical water-cooled SMR
  • Quick deployment: Deployable as early as 2028 thanks to proven know-how and construction techniques

Smaller and smarter, but still with proven technology:

  • Building on more than 30 years of ESBWR development, the BWRX-300 reduces scale and complexity resulting in an SMR that is smarter, safer, faster and less costly to both build and operate.
  • The construction technologies incorporated into the BWRX-300 design adopt advanced concrete solutions and innovative techniques that have been proven in the oil and gas, tunnelling and power industries.
  • Using a combination of modular and open-top construction techniques, the BWRX-300 can be constructed in 24-36 months while achieving an approximate 90 percent volume reduction in plant layout. In addition, reducing the building volume by about 50 percent per MW should also account for 50 percent less concrete per MW.
  • Simply put, the BWRX-300 represents a significant improvement in both affordability and advantageous size.
  • As a “smart reactor” the BWRX-300 uses natural circulation and passive cooling isolation condenser systems to promote simple and safe operating rhythms. In the global race for advanced nuclear power, the BWRX-300 sets itself apart with its proven, less complicated processes.
