THE BWRX-300 SMALL MODULAR REACTOR
COMPETITIVE, WORLD-CLASS SAFETY, PASSIVE COOLING
The BWRX-300 is a ~300 MWe water-cooled, natural circulation Small Modular Reactor (SMR) with passive safety systems. 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.
The BWRX-300 is based on the U.S. NRC-licensed, 1,520 MWe ESBWR and is designed to provide clean, flexible baseload electricity generation that is competitively priced and estimated to have the lifecycle costs of typical natural gas combined-cycle plants targeting $2,250/kW for NOAK (nth of a kind) implementations.
BENEFITS AND FEATURES
- World class safety: mitigates loss-of-coolant accidents (LOCA) enabling simpler passive safety
- Cost competitive: projected to have up to 60% less capital cost per MW when compared with typical water-cooled SMR
- Passive cooling: steam condensation and gravity allow BWRX-300 to cool itself for a minimum of seven days without power or operator action
- Quick Deployment: Deployable as early as 2028 thanks to proven know-how and construction techniques
A DRAMATIC REDUCTION IN SCALE AND COMPLEXITY
The BWRX-300 utilizes the ESBWR’s 30+ year development basis to help future plants operate smarter, faster and on a less costly basis.
Compared to the ESBWR, the BWRX-300 prides itself on achieving about a 90 percent volume reduction in plant layout. Notably, the innovative SMR is designed to reduce building volume by about 50 percent per MW, which should account for 50 percent less concrete per MW. The 1,520 MWe ESBWR has approximately 160,000 m3 of safety related concrete while the BWRX-300 has only 15,500 m3. The BWRX-300 will significantly improve the next generation of reactors due to its 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, the BWRX-300 sets itself apart with its proven, less complicated processes.
The BWRX-300 technology is highly supported in the nuclear energy industry and GEH is collaborating with several partners who are committed to creating the optimal reactor design needed to help customers achieve a strong and successful future. One such partner, Dominion, is proactively investing in the BWRX-300. GEH SMR Technologies Canada, Ltd., based in Marhkam, Ontario, supports the deployment of the BWRX-300 in Canada.
It is to be noted that most of the nuclear-related technology and components used in the BWRX-300 either have had many years of proven operating experience or have undergone significant testing and licensing as part of the ESBWR program. Moreover, the various 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. GEH continues to focus on reducing cost and schedule in order to enable the BWRX-300 to compete with natural gas combined cycle power plants and to help position nuclear plants generally to remain a vital part of the future power generation mix.
