Why nuclear?
Clean, compact, sustainable power
Always available
Decarbonizing the power generation industry is crucial to reaching net zero emissions. While the future of energy will be a mix of power generation technologies, low-carbon power sources like solar, wind and hydro aren’t always available. Nuclear power plants operate at much higher capacity factors than renewable energy sources, making them a highly available power source for customers concerned about energy security.
Why the BWRX-300?
Innovative, simplified, and cost-competitive
Powered by proven and commercially available fuel, the BWRX-300 features an innovative and simplified configuration, resulting in less concrete and steel needed for construction. The BWRX-300 is a cost-competitive solution that can be deployed for electricity generation and industrial applications, including hydrogen production, desalination, and district heating.
1
300 MW carbon-free power
Ideally sized for plant conversion from coal to nuclear
2
Innovative configuration
Simple and innovative with digital offerings that lower costs and improve safety.
3
Competitive cost
Less capital cost per MW when compared with typical water-cooled SMR.
4
Proven & reliable fuel
Licensed and proven fuel configuration with qualified facilities in the U.S. and Europe.
5
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.
6
Robust supply chain
Decades of experience building supply chains, supporting local jobs and economies.
7
Project certainty
Deployable globally as early as 2029 thanks to proven know-how and innovative construction techniques.

Take a closer look
The BWRX-300 supports decarbonization efforts by delivering clean, always available power to the grid and behind-the-meter applications. In addition, it can provide hot water and steam that can be used for district heating, clean hydrogen and fuel production, reverse osmosis, and direct air capture.
Leading-edge technology and construction
BWRX-300 features
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, tunneling and power industries.
Right-sized and cost-effective
Using a combination of modular and open-top construction techniques, the Nth-of-a-kind 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—a significant improvement in both affordability and advantageous size.
