The Global Standard For Fleet-Scale Nuclear Deployment

Westinghouse’s AP1000® technology powers the world. Since the first unit came online in 2018 through 2024, the global AP1000® fleet generated more than 245 TWh of electricity, enough to power a country the size of Spain for a year. Over its more than 80-year operating life, a single unit can generate enough electricity to power a city the size of London for nearly two decades. And the AP1000® plant is built to keep performing: the fleet holds industry records for first and second cycle refueling outages at just 28 and 19 days.

That proven performance is now the foundation for the next wave of innovation, with the AP300™ SMR sharing engineering, technology and supply chain infrastructure with the AP1000® reactor through Westinghouse’s APX technology platform, Westinghouse is extending its proven advanced reactor platform to a broader range of energy needs and markets.
