The International Symposium on Material Service Performance in Nuclear Power Plants-2019 Intelligent Monitoring and Reliability Assessment sponsored by Shanghai University and co-organized by our institute and other institutions was held on October 28-31, 2019. Xuehai Hall, Lehu New Building, Shanghai Baoshan Campus was held. The theme of this conference is "intelligent monitoring detection and reliability evaluation". Zhou Bangxin, Academician of Shanghai University, Professor Zhuang Zizhexiong, Academician of the Japanese Academy of Engineering, Tang Weibao, Chief Engineer of Shanghai Electric Nuclear Power Group, and Dai Zhimin, Deputy Director of Shanghai Institute of Applied Materials, Chinese Academy of Sciences, co-chaired the conference. A total of more than 100 representatives from relevant units at home and abroad, such as Tohoku University of Japan, Global Research and Development Center of GE Corporation of the United States, Oxford University of England, University of Manchester of the United Kingdom, and Korea Advanced Institute of Science and Technology, attended the international conference.

A total of 29 oral reports and 9 posters were arranged for the meeting. Attendees at the meeting exchanged the latest research progress on the safety and reliability of water-cooled reactor nuclear power plants related to material service performance, and experimental evaluation of material service performance of nuclear power plants. Professor Ren Jie from our college, on behalf of Professor Ren Yunlai, made a special academic report entitled "Study on the multi-ram forging technology for the high temperature-pressure valve body" at the meeting. This report takes the manufacture of a three-inch gate valve body by using the multi-directional die forging method as an example. The numerical simulation method is used to systematically study the sequence of the punches on the forming load, clamping force, horizontal punch load, and vertical punch load. Affecting the law, subsequent performance tests show that the mechanical properties of the valve body produced by the multi-directional die forging method are far higher than the requirements of existing standards. The report fully demonstrated the research results and technical advantages of our university in the field of multi-directional die forging in recent years, and was widely praised by the participating experts.

During the meeting, some representatives visited Shanghai Electric First Machine Tool Plant Co., Ltd. nuclear power equipment production base, our university's large-scale casting and forging manufacturing technology collaborative innovation center and Industry 4.0 intelligent manufacturing laboratory. The achievements of the industry-university-research cooperation and the development of the school's characteristics in the field of nuclear power large-scale forgings manufacturing in recent years have impressed all the participants.
