Advanced Boiling Water Reactor (ABWR)
Technology, Schedule, and Cost Confidence
The Advanced Boiling Water Reactor (ABWR) is the foundation
of GEH’s nuclear reactor portfolio. The Gen III design is available
today to meet power generation needs ranging from 1350 to
1460 MW net. It delivers proven advanced technology and
competitive economics.
ABWR already has an impressive track record. It is the world’s
first and only Generation III nuclear plant design in operation
today, providing the benefit of a combined 20 reactor-years of
operational experience. GEH’s first ABWR began commercial
operation at Kashiwazaki-Kariwa in Japan, in 1996. Three
additional ABWRs are operating in Japan with two more under
construction in Japan, and two in Taiwan. The ABWR is licensed
in the U.S., Japan and Taiwan.
The ABWR is a direct cycle Light Water Reactor that reflects 50
years of continued evolution from GEH’s initial BWR concept—
combining the best features from our worldwide BWR fleet.
Our well-established, global supply chain is already qualified
Simpler yet Safer Design with Advanced
and prepared today to support deployment of new nuclear
power plants.
• Reactor internal pumps – eliminates external recirculation
Benefits and Features of the ABWR
• Lowest-in-Class core damage frequency at power (1.6 x 10-7/year)
• Standardized design capable of further uprates
• 60-year Design life
• Modularized design to optimize construction schedule
• Demonstrated capital and O&M cost structure in Japan
• Significantly lower in staffing and maintenance costs per kWh than
the current U.S. installed base of Gen I and II nuclear reactors
• Integrated containment and reactor building – improved
seismic response, compact, and easier to construct
• Compact reactor building – less construction material and
shorter construction times
• Optimized modularization – module designs refined and proven
in real installations
• Sophisticated control systems – fully digital, providing reliable
and accurate plant monitoring, control, and diagnostics
• High integrity fuel, improved water chemistry,
and radiation source elimination – reduced radwaste
and occupational exposure
