On May 7, 2019, Oak Ridge National Laboratory of the United States held the “Innovative Laboratory Advanced Manufacturing Summit”, the conference focused3D printingTechnology to manufacture parts and components at a faster speed and lower cost.U.S. Secretary of Energy Perry visited3D printingTechnologically manufactured high-tech components, including the core components of a miniature nuclear reactor.
The trial-produced valve body is 140 mm long, 76 mm wide and 56 mm high. The project adopts SLM technology and uses laser to scan and solidify metal powder layer by layer, gradually stacking the valve body shape and complex internal flow channels, forming one time, saving materials and improving the stability of parts. Compared with traditional processes, it can shorten the manufacturing cycle. And it can meet the requirements of small batch rapid production and cost reduction.
“Compared with traditional design and manufacturing technology for nuclear power equipment from large to small processing,3D printingThe technology is the other way around, starting from the powder. “A nuclear power engineer analyzed to a reporter from China Business News that this makes the quality of nuclear power equipment more reliable.
It was learned from China General Nuclear Power that the successful trial-manufacture of the above-mentioned valve body will provide China General Nuclear Power for the subsequent establishment of nuclear power metal3D printingThe joint R&D center lays the foundation.Follow-up China Guangdong Nuclear Power will continue to carry out3D printingDesign optimization, parts repair, material and process development, standard system establishment, etc. related research.
It’s worth noting that China General Nuclear Power has previously announced that it uses metal3D printingThe end cover of the refrigerating machine of the compressed air production system manufactured by technology research and development has been implemented in the Daya Bay Nuclear Power Plant for engineering demonstration applications.
In addition to China General Nuclear Power, the China National Nuclear Corporation, which is also the three major nuclear power giants, independently researched and developed the third-generation nuclear power technology small nuclear reactor pressure vessel3D printingThe test piece has also passed the appraisal of scientific research results by 13 experts from the National Energy Administration, China Nuclear Power Development Center, National Nuclear Engineering Co., Ltd., Harbin Institute of Technology, Beijing Iron and Steel Research Institute and other units.
