核主泵水力优化设计研究现状与技术发展综述
Review on research status and technical development of hydraulic optimization design of reactor coolant pump
摘要
Abstract
Combined with the new situation of international nuclear power development and the deve-lopment and strategic layout of China's nuclear power technology,the development history of reactor coolant pumps,and the current technological development of the world's advanced nuclear power tech-nology and key equipment reactor coolant pumps were introduced,focusing on the hydraulic optimiza-tion design and safety.Taking China's independent third-generation nuclear power technology"Hualong One"HPR1000 and"Guohe One"CAP1400 as examples,the current status of the world's advanced nuclear power technology and key equipment reactor coolant pumps was introduced,with a focus on the hydraulic optimization design and safety of reactor coolant pumps.The advanced hydraulic optimization design of reactor coolant pumps at home and abroad was introduced,the causes of internal complex flow,pressure pulsation,generation and control of vortex structure,cavitation and other undesirable flow phenomena due to the special structure of reactor coolant pumps were analyzed,and the optimiza-tion design method of hydraulic components was summarized.The reactor coolant pump is the only high-speed rotating machinery in the nuclear island,and it is also the first-class equipment for nuclear safety.Whether the reactor coolant pump can operate normally is directly related to the safety of the whole nuclear power plant.The complete localization of the reactor coolant pump research and develop-ment is the"bottleneck"problem plaguing the development of China's nuclear power.Therefore,in-depth study of the complex internal flow of the reactor coolant pumps and mastering the hydraulic opti-mization design method of the reactor coolant pumps with independent intellectual property rights are of great significance for the development of China's nuclear power technology.关键词
