AP1000 Reactor Coolant Pump Completes Qualification Testing

After 50 service cycles and more than 500 hours in operation, the lead reactor coolant pump for Westinghouse’s new AP1000 reactor recently concluded testing.

In a release, Westinghouse said the positive test results will allow the pumps’ installation at China’s Sanmen unit 1, the first AP1000 under construction. The first two pumps will be shipped to the plant this quarter.

China’s State Nuclear Power Technology Corporation Chairman Wang Binghua was quoted as saying the tests demonstrate the companies “have jointly overcome the challenges with the AP1000 RCPs, which are among the most critical components of the AP1000 design ... We expect that the successful delivery of the RCPs will ensure that China's first AP1000 unit at Sanmen will go online as projected in 2013.”

Curtiss-Wright business segment Flow Control performed the testing. The firm’s Cheswick, Pa., factory will produce 16 of the pumps for the first four AP1000s in China. Several more AP1000s are under construction in China and the U.S., including two at Plant Vogtle in Georgia. Preliminary site work is underway for another two units at the V.C. Summer plant in South Carolina.

AP1000的历史：
　西屋公司在已开发的非能动先进压水堆AP600的基础上开发了AP1000。
　　根据美国核管理委员会(United States Nuclear Regulatory Commission 简称NRC)官方网站信息，2002年3月28日，西屋公司向核管会提交了了AP1000的最终设计批准以及标准设计认证的申请。2004年9月13日获得了NRC授予的最终设计批准（Final Design Approval）。核管会于2005年12月14日投票通过了AP1000标准核电站的最终设计认证条例（Final design certification rule)，并于2006年1月23日获得签署。直至2010年12月1日，西屋向NRC提交了AP1000设计控制文案（Design control document）的第18次修改。根据《科学美国人》（Scientific American）的报道，核管会估计会在2011年9月会完成对AP1000的整体设计认证。按照西屋公司的预期，2016年美国会开始建造AP1000型核电站，这将会是美国自上世纪70年代以来首次恢复核电站的建设。
