The nuclear safety class valve prototype appraisal meeting of large pressurized water reactor nuclear power plant was successfully held

entrusted by the national energy administration, the China Machinery Industry Federation hosted the nuclear safety class valve prototype appraisal meeting of large pressurized water reactor nuclear power plant in Suzhou. Seven nuclear class I The nuclear level II valve prototype successfully passed the expert group evaluation

entrusted by the national energy administration, China Machinery Industry Federation hosted the nuclear safety level valve prototype evaluation meeting of large pressurized water reactor nuclear power plant in Suzhou. Seven nuclear level I and nuclear level II valve prototypes jointly developed by China nuclear suvalve Technology Industry Co., Ltd. and China Guangdong Nuclear Engineering Co., Ltd. successfully passed the expert group evaluation. The expert group agreed that the development of the seven prototypes is a successful example of independent innovation through the combination of production, study, research and application of enterprises. Here, we fill the domestic gap according to the development of four ball machine two-stage wedge parallel plate electric gate valve and pneumatic diaphragm valve, which has reached the advanced level of similar foreign products in technology, and further promoted the localization process of nuclear power valves

Qiu Jiangang, deputy general manager of China National Nuclear Industry Corporation and chairman of China Nuclear Science and Technology Corporation, Huang Li, director of the technical equipment department of the national energy administration, ye Qizhen, academician of the Chinese Academy of engineering, Sui Yongbin, chief engineer of the China Machinery Industry Federation, ye Darong, deputy director of the major office, as well as China National Nuclear instrumentation and Equipment Corporation, China Nuclear Power Engineering Corporation The relevant leaders of China Guangdong Nuclear Power Engineering Co., Ltd. and other units should replace the sealing ring or combined gasket guide in time, and experts attended the appraisal meeting

Qiu Jiangang said, "for a long time, CNNC technology has been developing the manufacturing of nuclear power localized equipment as an industry. Now, CNNC technology will take the nuclear first-class high-end valves as the next development direction. Similarly, we also hope that owners will work with our equipment manufacturers to expand this industry in more flexible ways of cooperation and jointly promote the localization process of nuclear power valves."

Huang Li said that from less than 4% in Ling'ao phase II to more than 40% in Fuqing and Fangjiashan, the localization of pumps and valves in China has made rapid progress in recent years. As the pacesetter in China's valve industry, CNNC technology has made new breakthroughs in the key system valves of nuclear power, breaking the foreign technological monopoly, improving the localization rate of nuclear power equipment, and has become the backbone of the localization of nuclear power equipment. The government will be duty bound to actively provide strong support to expand its market. In addition, owners should also actively combine production, study and research with manufacturers to jointly raise the localization level of nuclear power equipment to a new level

at the meeting, it was also learned that at present, China nuclear technology has successfully developed new nuclear grade valves of 8 specifications that the 3 companies will resume trading after the relevant announcements are made through the designated media, and all of them have successfully passed the expert appraisal of the national authoritative department. In addition to the automatic and full-automatic spring tension and compression testing machines manufactured by Jinan new era Gold Testing Instrument Co., Ltd., CNNC science and technology is actively promoting the localization process of nuclear grade key valves of million kilowatt nuclear power plants in accordance with the national nuclear energy development plan
