The Westinghouse AP1000® Pressurized Water Reactor (PWR) is simply more advanced than other nuclear power plant technologies available today in the worldwide commercial marketplace. Today, Westinghouse is more focused than ever on making clean, safe and reliable energy possible and practical. Safety is always the number one priority of the AP1000 plant. During a station blackout, or loss of all electrical power, the AP1000 plant's passive safety system shuts down the reactor automatically, with no need for human intervention for up to 72 hours. The AP1000 plant's truly innovative technology harnesses natural forces like gravity, convection and condensation to achieve safe shutdown of the reactor. In 2018 and early 2019, 4 AP1000 units entered commercial operation, marking the first successful deployment of Generation III+ reactors. They then went on to achieve record-breaking first cycle and first refuelling outage performance. The AP1000 plant is now recognized as the most advanced, proven nuclear technology available, delivering safe, clean, reliable power.
