Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Power, Ltd. have delivered four of the nuclear turbine power generation facilities for commercial-use, the world's first AP1000 reactors at Sanmen Nuclear Power Station Units 1 and 2 and Haiyang Nuclear Power Station Units 1 and 2 in China. This project consists of equipment supply and technology transfer to a Chinese turbine manufacturer. We designed the steam turbines and heat exchangers and supplied the key equipment for the secondary turbine plant. For the steam turbine, a 54-inch integral shroud blade was adopted as the last blade and advanced technologies were adopted to improve performance, such as eliminating the control stage of the high-pressure turbine and improving the low-pressure exhaust casing. Both plants have had no issues since fuel loading and were able to start commercial operation early after a very short test operation period of 4 to 5 months, so we were highly evaluated for our technological capabilities, performance, quality and reliability from customers.
