Only SMR based on Deployed, Operating & Advanced Reactor Technology

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.

Our AP1000® reactor is already 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.

Based on Real-World Proven Technology

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:

• More than 30 years licensing advanced passive safety technologies with global regulators.
• Utilizing an established infrastructure, including a mature supply chain and Operations & Maintenance services.
• Westinghouse is a world leader in delivering nuclear fuel. AP300 SMR utilizes our robust fuel design that incorporates a variety of proven and advanced fuel features, and a four-year refueling cycle.
• Uses advanced proven Instrumentation & Controls technology to simplify operations and increase reliability.
