201 to meet its own needs and even the needs of the world. On August 1, 2004, five experts from China Nuclear Power Research and Design Institute and China Nuclear suvalve Technology Co., Ltd. came to Changzhou Power Plant Auxiliary Machinery Co., Ltd. to accept the design and manufacturing documents and field tests of the small reactor main feedwater control valve straight stroke pneumatic actuator prototype

the prototype of the direct stroke pneumatic actuator for the main feedwater control valve of small reactor is used for the flow control valve of the modular feedwater control system for small reactor of nuclear power plant. It is a joint development project of China Nuclear Power Research and Design Institute and CNNC suvalve. This kind of nuclear grade direct stroke pneumatic actuator is still blank in China

the acceptance of the prototype will fill the gap in China. It is of great significance to promote the development of China's nuclear power supporting technology and enhance the competitiveness of nuclear power products localization

class 1E DC motor of nuclear fuel pump on August 19, 2014, the general Tin Branch with ball screw of the 703 Research Institute of CSIC and Shanghai Nuclear Engineering Research and Design Institute accepted the two class 1E DC motors of nuclear fuel pump developed by the company in the conference room on the third floor of Changzhou Power Station auxiliary machinery plant. 10 [cross head]

acceptance is divided into two groups. The document group consulted relevant technical documents in the design and manufacturing process, incoming inspection reports of materials and purchased parts, prototype test reports, quality plan implementation, etc. The other team conducted relevant inspections and performance spot checks on the two prototypes according to the test program, and formed on-site witness records

the purchaser Wuxi 703 Institute believes that the acceptance documents submitted by the company are complete and meet the requirements, and the class 1E DC motor meets the contract and procurement technical requirements. It is hoped that the company will provide support in the follow-up identification test process of Wuxi Branch of the 703 Research Institute with rich industry experience and development trend
