ESBWR Nuclear Power Plant

World’s safest reactor – Safer. Simpler. Smarter

The Economic Simplified Boiling Water Reactor (ESBWR) is a 1520 MWe Generation III+ boiling water reactor.  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 7 days.

Building upon ABWR's proven technology, ESBWR achieves even greater simplicity in design, using natural circulation, it uses 25% fewer pumps and mechanical drives than existing acting safety plants.

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

Benefits and Features of the ESBWR

  • Designed to be Simpler yet Safer than ever before 
    • Residual heat transferred to the atmosphere 
    • 11 systems eliminated from previous designs 
    • 25 percent of pumps, valves, and motors eliminated

ESBWR Quick Facts

The ESBWR design's core damage frequency at power of 1.7 x 10-8/year is the absolute lowest of any advanced reactor design available in the industry today The ESBWR is designed to generate electricity while producing nearly zero greenhouse gas emissions during operation. Compared to typical generation on the U.S. grid, the electricity produced by an ESBWR would avoid the emission of approximately 7.5 million metric tons of CO2 per year.
