AP1000® Pressurized Water Reactor

Westinghouse Electric Company sets a new industry standard with the AP1000® plant.

The established design of the AP1000 plant offers three distinct advantages over other designs:

  • Unequaled safety
  • Economic competitiveness
  • Improved and more efficient operations

Based on nearly 25 years of research and development, the AP1000 plant builds and improves upon the established technology of major components used in current Westinghouse-designed plants. These components include:

  • Steam generators
  • Digital instrumentation and controls
  • Fuel
  • Pressurizers
  • Reactor vessels

Simplification was a major design objective for the AP1000 plant. The simplified plant design includes overall safety systems, normal operating systems, the control room, construction techniques, and instrumentation and control systems. The innovative AP1000 plant design features:

  • Fewer safety-related valves
  • Less safety-related piping
  • Less control cable
  • Fewer pumps
  • Less seismic building volume
