During testing on Thursday, May 13, the AP1000™ pressurized water reactor RCP successfully completed testing in ambient operating conditions. On Saturday, May 15, testing was successfully performed at normal operating temperatures and pressures. All test objectives for both tests were met. The tests were completed ahead of schedule, and witnessed by representatives of China’s State Nuclear Power Technology Corporation and owners of the four AP1000™ PWR units currently being constructed in China.
These tests are important steps in the final qualification process of the AP1000™ RCP. Curtiss-Wright EMD and Westinghouse will complete final qualification testing of the RCP over the next 12 months. This will ensure safe and reliable RCP operation in the world’s first-ever built Westinghouse AP1000™ nuclear power plants under construction in China, and for future AP1000™ plants that will be built in the U.S. The AP1000™ PWR is the only Generation III+ passive safety systems reactor certified by the United States Nuclear Regulatory Commission.
AP1000™ Pressurized Water Reactor Coolant Pump
Manufactured by Curtiss-Wright Flow Control – EMD for Westinghouse Electric Company, the AP1000™ RCPs are high-inertia pumps that are highly reliable, low-maintenance, hermetically sealed canned-motor pumps, which circulate the reactor coolant through the reactor core, loop piping, and steam generators. Curtiss-Wright EMD, a business unit of the Curtiss-Wright Flow Control Company, is the world’s premier designer/builder of reactor coolant pumps, having produced more than 350 pumps for the existing commercial nuclear reactor fleet and over 1200 for the U.S. Navy. In the past 40 years, EMD has successfully developed eight canned RCPs for specific unique applications. These pumps are highly reliable, with many running problem free for 30 years.
Sixteen RCPs for China’s first Generation III+ reactors will be built in the Western Pennsylvania plant, demonstrating how nuclear plant exports are driving high quality manufacturing in the U.S. The Curtiss-Wright EMD factory is one of over a dozen U.S.-based factories that will be directly involved in exporting products to the AP1000™ projects in China. Excellent cooperation is ongoing with U.S. and China in the testing and manufacturing of additional reactor components for the China nuclear program.
