Building the world’s best nuclear reactors

For more than 60 years, GE and Hitachi have been designing and building the world’s safest boiling water reactors (BWRs). 

Today, GE Hitachi offers the BWRX-300, a small modular reactor designed to be cost-competitive with other forms of generation, the sodium cooled PRISM, and the ESBWR and ABWR. In 2020, GEH and TerraPower introduced the Natrium™ power production and storage system.  

In addition to our technology, we also provide a full range of new nuclear plant services and can tailor each solution to help customers overcome new plant challenges and experience better project development and execution.



Competitively priced with world-class safety features and passive cooling

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. Designed to provide clean, flexible baseload electricity generation, the BWRX-300 is competitively priced and estimated to have the lifecycle costs of typical natural gas combined-cycle plants.



Flexible, clean energy at a competitive cost

GE Hitachi and TerraPower have developed the Natrium™ reactor and energy system as a cost-competitive, flexible technology that supports load following, energy storage and industrial process heat applications. With a 345 MWe sodium fast reactor, integrated energy storage and flexible power production, the Natrium technology offers carbon-free energy at a competitive cost and is ready to integrate seamlessly into electric grids with high levels of renewables.

Technology, Schedule and Cost Confidence

Solving one of the world’s toughest issues … spent nuclear fuel

PRISM offers the most efficient, clean, cost-effective option for turning nuclear waste into low carbon energy.

GE Hitachi Nuclear Energy’s next evolution of sodium-cooled reactor technology is PRISM, a reactor that uses liquid sodium as a coolant. This coolant allows the neutrons in the reactor to have a higher energy (sometimes called fast-reactors) that drive fission of the transuranics, converting them into short-lived "fission products."

This reaction produces heat energy, which is converted into electricity in a conventional steam turbine.




Safer. Simpler. Smarter.

The Economic Simplified Boiling Water Reactor (ESBWR) is a 1520 MWe Generation III+ boiling water reactor. The ESBWR is the world’s safest reactor. It has the lowest core damage frequency (industry standard measure of safety) of any Generation III or III+ reactor and can safely cool itself with no AC electrical power or human action for more than seven days.

Building upon the ABWR's proven technology, the ESBWR achieves even greater simplicity in design. By using natural circulation, it has 25 percent fewer pumps and mechanical drives than existing active safety plants.

It is projected to have the lowest operating, maintenance and staffing costs per megawatt hour of any reactor technology available today.



Technology, Schedule and Cost Confidence

The Advanced Boiling Water Reactor (ABWR) is the world’s safest reactor in operation today. The Gen III design is available to meet power generation needs ranging from 1350 to 1460 MW net.

Using modular construction, several ABWR’s have been built on time and budget in Japan.
