Pressurized Water Reactor

The established design of the AP1000® plant offers three distinct advantages over other designs: Unequaled safety, economic competitiveness and 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
