On May 16, 2021, the appraisal meeting of the prototype of nuclear fuel transportation channel gate valve jointly developed by China Nuclear suvalve Technology Industry Co., Ltd. and Shanghai Nuclear Engineering Research and Design Institute Co., Ltd. was held in Suzhou. The appraisal meeting was organized by the China Nuclear Energy Industry Association, and the appraisal expert group was from the China nuclear industry group. On May 16, 2021, the appraisal meeting on the development results of the prototype of nuclear fuel transportation channel gate valve jointly developed by China Nuclear suvalve science and Technology Industry Co., Ltd. and Shanghai nuclear engineering research and Design Institute Co., Ltd. was held in Suzhou. The appraisal meeting was organized by China Nuclear Energy Industry Association, and the appraisal expert group was composed of representatives from China Nuclear Industry Corporation, National Nuclear Power Technology Corporation, State Power Investment Group Limited, Shanghai Jiaotong University, East China University of technology, nuclear and radiation safety center of the Ministry of ecological environment, China Nuclear Power Engineering Co., Ltd., China Nuclear Power Research and Design Institute, China Guangdong Nuclear Engineering Co., Ltd Academician Ye Qizhen served as the director of the expert committee. Chen Fang, director of the association, presided over the meeting, and Peng Xinying, Secretary of the Party committee and chairman of the board of directors of CNNC science and technology, attended the meeting and made a speech. At the same time, leaders and guests from State Power Investment Corporation, Nuclear Power Engineering Corporation, Shanghai Puyuan and other units were also invited

the expert group conducted a comprehensive review and inquiry on the development results of the prototype of the fuel transportation channel gate valve through on-site inspection of the fuel transportation channel gate valve laboratory, witnessing the experiment and listening to the summary report of the development work, and formed a unanimous appraisal opinion. It recognized that the nuclear grade fuel transportation channel gate valve has independent intellectual property rights, fills the domestic gap, reaches the international advanced level, and can be applied to cap1400/cap1000 and other nuclear power projects, It has good social and economic benefits

Qiu Jian, director of Shanghai Nuclear Engineering Research and Design Institute, pointed out that the development of fuel transportation channel gate valve is an important incremental collection method in the valve localization puzzle; In the whole process of valve localization, CNNC technology has undertaken the development of a large number of key valves, including blast valves, main steam isolation valves and some high-grade globe valves, and has made many achievements. On the basis of these achievements, Shanghai Institute of nuclear technology and CNNC technology will complete the layout of the whole industrial chain and continue to complete the localization of valves

Peng Xinying, Secretary of the Party committee and chairman of China (1) universal material testing machine nuclear science and technology, pointed out that with the strong support of Shanghai Institute of nuclear engineering, China Nuclear Science and technology has made a major breakthrough in the research and development of the prototype of nuclear fuel transfer channel gate valve. The nuclear fuel transfer channel gate valve has good application prospects, which can be applied and promoted not only in pressurized water reactor nuclear power projects, but also in other similar applications. With the successful appraisal of the achievements of the fuel transportation channel gate valve, CNNC technology has achieved full coverage localization of the third-generation nuclear power cut-off valves, and has also taken a great step in the localization process of the valve industry. CNNC technology will continue to work to ensure the self-reliance, self-improvement and self-control of China's third-generation nuclear power valves with the goal of full coverage and complete supply capacity of the third-generation nuclear power
