【Ten Years of Rapid Development in Chemical Engineering Equipment】From 1978 to 2022: Successful domestic development of the drive mechanism for the main steam isolation valve in the **CAP1400 major scientific and technological project】
Thread Content
Witnessing the ten-year rapid development of chemical engineering equipment, I praise the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families enjoy peace and health. By contributing our ideas, we can create a more lively atmosphere for discussion; HaiChuan becomes even better with your participation. Everyone is welcome to engage more actively in discussions on this forum. --------------------------------------------------------------In January 2022, at China National Nuclear Corporation Su Valve Technology & Industry Co., Ltd. (hereinafter referred to as CNNC Technology), the integrated testing of the prototype of the CAP1400 main steam isolation valve actuation device, developed jointly by CNNC Technology and the Shanghai Nuclear Engineering Research and Design Institute, was successfully completed. This marks the successful localization of the development of this key technological component for the CAP1400 main steam isolation valve.
The main steam isolation valve of the CAP1400 nuclear power unit is located on the main steam pipeline of the nuclear power plant; it serves to isolate the containment structure as well as the steam generator. The reliable operation of the drive mechanism for this valve is directly related to the safety of the nuclear power plant and the reliability of power generation, making it one of the key components in such plants.
The Ministry of Science and Technology of the People’s Republic of China has designated the development of the drive mechanism for the CAP1400 main steam isolation valve as a key project in the field of science and technology. CNNC serves as the leading entity for this project, working together with Shanghai Nuclear Engineering Research and Design Institute Co., Ltd. to carry out the development efforts. The goal is to achieve domestic production of the world’s largest drive mechanism for CAP1400 main steam isolation valves, and to conduct comprehensive testing through the development of test prototypes. The evaluation meeting for the results is scheduled to be held in the second half of 2022. Through research and development, China National Nuclear Corporation has mastered the core technology related to the drive systems for main steam isolation valves in large-scale, advanced pressurized water reactor nuclear power plants. It has thus developed CAP1400 main steam isolation valve drive systems that possess independent intellectual property rights, satisfying the needs of China’s nuclear power development. Moreover, this will help break the foreign monopoly and enhance the company’s competitiveness in the international market.
Thanks for sharing! Stay ahead of the technological frontier!
