High Quality Content by WIKIPEDIA articles! The Qinshan Nuclear Power Plant is a multi-unit nuclear plant under construction in the People's Republic of China. When completed, it may hold the record for the most nuclear reactors on one site; however, since the majority of the units are mid-size, it may be surpassed by other plants in terms of generating capacity. The construction of the units is divided into separate stages. Stage I involved construction of the small-scale (~300 MW) Unit-1 only, but was the first domestically designed and constructed nuclear power plant in the nation (95 percent of components came from domestic manufactures). That unit has so far operated for more than 10 years without an event rating 2 on the International Nuclear Event Scale. Stage II the next set of reactors were mid-scale plants (~600 MW) but still of Chinese design. The steam generators were made by the Shanghai Boiler Factory in conjunction with Westinghouse.
