Nuclear Components Manufacturing
Significant progress has been made in the development of homegrown technologies and expertise in designing and manufacturing key components and materials for nuclear power plants, especially for nuclear islands and conventional islands. A network of manufacturing hubs for the nuclear power industry have come into being, such as large forgings & forgings manufacturing hub led by the China First Heavy Industries, the China National Erzhong Group and the SHMP Casting & Forging Co., Ltd.; large nuclear power component manufacturing hub where the Dongfang Electric Corporation, the Shanghai Electric (Group) Corporation and the Harbin Electric Corporation operate; and nuclear grade pump and valve manufacturing hub where the Shenyang Blower Works Group, the SUFA Technology Industry Co., Ltd., the CNNC, the Shanghai Electric-KSB Nuclear Pumps & Valves and the Dalian DV Valve Co., Ltd. have established their manufacturing bases. Key components such as pressure vessels, steam generators, primary pipes, control rod drive mechanisms, and digital instrumentation and control systems, as well as core materials such as large forgings, nuclear-grade zirconium materials, 690U tubes, and nuclear-grade welding materials, are designed and manufactured domestically. Over 88% of key components and materials for 1,000 MWe-class Gen III reactors are indigenously made. China now has the capacity to manufacture 8-10 full sets of reactor equipment annually, and the need for large-scale nuclear power plant construction can be met.
