Building the world’s best nuclear reactors
For nearly 60 years, GE Hitachi has been building the world’s safest boiling water reactors (BWRs).
Today, we offer the world’s two safest light water reactors, the ESBWR and the ABWR. We have also developed a sodium cooled reactor, PRISM, to address one of the world’s most difficult challenges, spent nuclear fuel.
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 ABWRs have been built on time and budget in Japan.
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 the PRISM (Power Reactor Innovative Small Modular) reactor. PRISM is 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.
