The first engineering application of 3D printing technology in domestic commercial nuclear power plants

CGNPC announced on the 11th that it will use the metal 3D printing technology to develop and manufacture the compressed air production system chiller end cover, and realize the demonstration application of the Daya Bay Nuclear Power Plant, the first large-scale commercial nuclear power plant in China. This is the first time that 3D printing technology has been successfully applied to domestic commercial nuclear power plants, which indicates that 3D printing technology has achieved a major leap from theoretical research, technical analysis to engineering application in the field of nuclear power.

Qin Yuxin, deputy general manager of China Guangdong Nuclear Power Operation Co., Ltd., introduced the company's key technology research in the process of manufacturing and repairing spare parts and parts for nuclear power plants in 2016, with EAM235 alloy (mainly composed of carbon and silicon). Manganese, chromium, nickel, molybdenum, copper and other elements are raw materials. The advanced manufacturing technology of 3D printing is made by using fused additive materials. The end cap of this type of refrigerator is successfully solved due to equipment modification of foreign manufacturers and spare parts are not available. The problem of goods.

Qin Yuxin expects to apply 3D printing emerging manufacturing technology to the manufacture and repair of nuclear power plant spare parts and parts, and will bring revolutionary changes to the design, research and development, manufacturing, repair, spare parts guarantee and inventory management of future nuclear power equipment. .
