In February, 1997, Hitachi, Ltd., received an order from AECL (Atomic Energy of Canada Limited) for two sets of 728-MW steam turbines for Qinshan Phase-III Nuclear Power Station in China, for which CNNC/TQNPC (China National Nuclear Corporation/Third Qinshan Nuclear Power Company Ltd.) is the end user. Hitachi completed manufacturing the No. 1 steam turbine in April 2000 and the No. 2 steam turbine in October 2000. These are Hitachi's first large-scale steam turbines for an overseas nuclear power station that use 1,500-rpm 52-inch(132-cm)-long last-stage blades. To improve the thermal efficiency, we used an improved MSR (moisture separator reheater). The condenser tubes were arranged for higher heat-exchange efficiency, and advanced debris filters were used. To promote the local production of power-station equipment in China, Hitachi and CNNC founded a joint venture of DHME (Dalian Hitachi Baoyuan Machinery & Equipment Co., Ltd.) in Dalian, China, to manufacture heat exchangers and other equipment for the project including condensers, MSRs, and feed-water heaters.
