Overview
The BWRX-300 SMR: an evolution in reliable, carbon-free power
Building on a 60-year legacy of innovative design and operating experience, the BWRX-300 small modular reactor can be deployed in a variety of applications. Its simplified, modular configuration—using licensed, operational systems from previous GEH plant designs—can be constructed in record time. It also has an exponentially smaller footprint, requiring fewer operating and security personnel than comparable plants.

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.
Passive safety systems for LOCA mitigation
The BWRX-300’s compact design uses natural circulation and passive cooling isolation condenser systems to help mitigate large loss-of-coolant accidents (LOCAs). This allows the reactor to passively cool itself for a week without power or operator action. The reactor can be cooled indefinitely by adding more water to the isolation condenser pools.
