Westinghouse, Curtiss-Wright test AP1000 reactor coolant pump

Pittsburgh, April 17, 2012 — Westinghouse Electric Co., Curtiss-Wright Corp., and the State Nuclear Power and Technology Corp. of China completed the design, manufacture and qualification of the lead AP1000 Reactor Coolant Pump.

Curtiss-Wright performed qualification of the RCP at its Flow Control business segment's electromechanical division facility in Cheswick, Pa.

The conclusion of qualification testing of the AP1000 RCP, including 50 service cycles and more than 500 total operating hours, clears the way for installation of the RCPs at Sanmen Unit 1 in China, the first AP1000 reactor to be built in the world. The shipment of the first two RCPs for Sanmen 1 is expected to occur in the second quarter of 2012.

The completion of the RCP Endurance Test has demonstrated that SNPTC, Westinghouse and Curtiss-Wright/EMD have jointly overcome the challenges with the AP1000 RCPs, which are among the most critical components of the AP1000 design.

Successful delivery of the RCPs will ensure that China's first AP1000 unit at Sanmen will go online as projected in 2013. The SNPTC will continue to strengthen its ties with Westinghouse and Curtiss Wright EMD to further promote AP1000 technology and the growth of nuclear energy.

Curtiss-Wright will build 16 RCPs for the first two AP1000 plants in China at its expanded EMD facility in Cheswick, PA. Each plant is supported by two AP1000 reactors, while each reactor holds four reactor coolant pumps.

Sanmen 1 is the flagship AP1000 reactor, with seven more reactors already under construction in both China and the U.S.: one more at Sanmen; two at the Haiyang site in Shandong Province, China; two at Southern Nuclear's Vogtle site in Georgia; and two at the SCANA V.C. Summer site in South Carolina.

Additional AP1000 plants are anticipated over the next decade in the U.S. and around the world, solidifying the AP1000 design as a foundation for the next generation of nuclear plants by employing passive safety systems, which rely only on natural forces to safely shutdown and remain cool.
