The Westinghouse AP300™ Small Modular Reactor is the most advanced, proven and readily deployable SMR solution. Westinghouse proudly brings 70+ years of experience developing and implementing new nuclear technologies that enable reliable, clean, safe and economical sources of energy for generations to come.
The AP1000® reactor is proving itself every day, around the globe. Currently, four units utilizing AP1000 technology are operating in China, setting performance records. Six more are under construction in China and one AP1000 reactor is operating at Plant Vogtle in Georgia while a second nears completion.
Our AP300 SMR leverages that operating experience, as well as tens of millions of hours on AP1000 reactor development.
Gain the benefits of the record-setting Westinghouse AP1000 PWR technology in a smaller power output to augment the backbone of your community energy system.
The AP300 SMR complements the AP1000 reactor for a cleaner energy mix, energy security, and grid flexibility and stabilization.
The AP300™ SMR, 300MWe (900MWth), is based on the licensed and operating AP1000 pressurized light water technology that has demonstrated industry leading reliability.
The Westinghouse AP300 SMR delivers on the promises of small modular reactors: smaller scale, modular construction for efficient build schedules, state-of-the-art safety and reliability.
The benefits of basing AP300 on the proven AP1000 reactor include:
