Recently, China General Nuclear Power Group released the end cap of compressed air production system using 3D scanning technology combined with metal 3D printing technology, and realized the demonstration application of the first million kilowatt large commercial nuclear power plant in China, Daya Bay Nuclear Power Station. . This marks a breakthrough in the research on key technologies in the manufacturing and maintenance of spare parts and components for nuclear power plants by CGN's 3D printing technology.

Some equipments in the field of nuclear power are complex in structure and harsh in operating environment, and have extremely high requirements on mechanical performance; in particular, some foreign imported equipment, long spare parts procurement cycle, and high procurement costs. The 3D scanner combined with 3D printing technology has the advantages of integrated complex net forming, short manufacturing cycle, high material utilization rate and excellent product performance, which can not only optimize product design, improve equipment manufacturing quality, and reduce spare parts procurement cost. It also provides quick and efficient supply of on-site emergency spare parts and optimizes spare parts inventory structure.

It is reported that since 2016, China Guangdong Nuclear Power Group Co., Ltd., a subsidiary of China General Nuclear Power Group Co., Ltd., has taken the lead in researching and applying 3D printing technology in the field of nuclear power, and has carried out the key technology of 3D printing technology in the manufacture and maintenance of spare parts and parts of nuclear power plants. Research 'scientific research projects.

CGNPC is China's largest and the world's third largest nuclear power enterprise. At present, it has 20 nuclear power generating units and 8 nuclear power units under construction, with a total installed capacity of 31.47 million kilowatts. Qin Yuxin said that it is foreseeable to apply 3D scanning technology and 3D printing manufacturing technology to the manufacture and repair of nuclear power plant spare parts and parts, and to design, research and develop, manufacture, repair, and spare parts support and inventory management processes for future nuclear power equipment. Bring revolutionary changes.
