The brief

Analyst view
  • Westinghouse is headquartered in Cranberry Township, Pennsylvania and is led by President and CEO Dan Sumner (appointed April 2026).
  • Six AP1000s operating globally; 11 under construction; selected for Poland, Ukraine and Bulgaria.
  • DOE committed $17.5B (June 2026) for long-lead items on up to 10 AP1000s across five utilities.

Technical approach

As reported
Design

Passive safety systems

AP1000 is 1200 MW with passive safety; AP300 scales to 300 MW with single-loop configuration.

Simplification

AP300 modular design

Eliminates one steam generator and pump versus AP1000; reduces complexity and cost.

Supply Chain

Proven manufacturing

Leverages 18 AP1000 reactor-years of operation and established Westinghouse supply base.
