China starts building 3rd-generation nuclear plant

SANMEN—China began excavation for the foundations of the world’s most advanced nuclear reactor in Sanmen City in the eastern Zhejiang Province on Tuesday.
The No. 1 reactor in Sanmen nuclear power plant will use the third-generation AP1000 technology, which was transferred from the US-based Westinghouse Consortium. It has never been used in any operating power plant previously, said Zhao Hong, a State Nuclear Power Technology Corp. (SNPTC) engineer.
Builders plan to excavate a hole 12 meters deep and more than 20 meters in diameter to house the reactor. It is expected to go into commercial operation in 2013. “The excavation started one month earlier than the original plan thanks to the support from all sides,” Zhao said, adding concrete pouring would start in March 2009.
Sanmen Nuclear Power Corp. will install six AP1000 nuclear generating units, each with a power capacity of 1.25 million kilowatts, before eventually becoming self-sufficient in the AP1000 technology.
In July, China reached an agreement with Westinghouse Electric Co. to build four nuclear power plants in the country — two in Sanmen and two in Haiyang City in the eastern Shandong Province. The construction of the Haiyang plant will begin later this year. China currently has 11 nuclear generating units in operation. Three use domestic technologies, two are Russian, four are French and two are Canadian designed. All employ second-generation technologies.
