GEH’s BWR portfolio

Built on a legacy of safer and efficient operation

GE’s history of boiling water reactor (BWR) technology dates to the 1950’s. In 1957, the company’s Vallecitos boiling water reactor was the first privately owned and operated nuclear power plant to deliver significant quantities of electricity to a public utility grid. Over the next several decades, more than 60 GE BWRs went into operation with the first Advanced Boiling Water Reactor (ABWR) entering operation in 1996. GEH’s Generation III+ reactor, the Economic Simplified Boiling Water Reactor (ESBWR) was certified by the U.S. Nuclear Regulatory Commission in 2014.

GEH’s portfolio of modular reactors offer the safest and most efficient nuclear energy generation capability available. Plus, we offer a full range of new and existing nuclear plant services to help you achieve greater project development, execution, and maintenance.


Advanced Boiling Water Reactor (ABWR)

The ABWR is the foundation of GEH’s nuclear reactor portfolio. The first Generation III nuclear plant operating, it offers the benefits of a combined 20+ reactor-years of safe, successful operation

Features and benefits

Technology, schedule, and cost confidence

High certainty of delivery cost and schedule based on experience gleaned from delivering past units. This greatly lowers investment risks to new owners.

Long life

Designed to operate for at least 60 years.

Enhanced construction

Modularized for quick construction and faster time to operation; capable of further uprates.


Significantly lower staffing and maintenance costs/kWh than current Generation II reactors.

Radiation reduction

High integrity fuel, improved water chemistry; lower radwaste and occupational exposure.


Economic Simplified Boiling Water Reactor (ESBWR)

Built upon the ABWR’s proven technology, the ESBWR achieves even greater simplicity in design. Using natural circulation, the ESBWR has 25% fewer pumps and mechanical drives than existing active safety plants.

Features and benefits

Created to be even simpler and safer

High degree of delivery cost and schedule based on experience gleaned from delivering past units. This greatly lowers investment risks to new owners.

Heat transfer

Residual heat is transferred to the atmosphere


11 systems eliminated from previous designs

Simplified configuration

25% of pumps, valves, and motors eliminated

High capacity

1520 MWe

Environmentally conscious

Saves 7.5 million metric tons of CO2 per year

Operationally approved

U.S. Nuclear Regulatory Commission certified design since 2014
