The nuclear valve prototype of Shanghai No.1 nuclear valve passed the review of design and qualification test outline

September, 2017, The China General Machinery Industry Association hosted a meeting in Shanghai. The most fundamental and basic task of the Shanghai I nuclear valve stock is to enter the new normal of medium growth. Under the new normal, the Main Feedwater regulating valve, nuclear secondary electric gate valve, stop valve and regulation of the megawatt pressurized water reactor nuclear power plant jointly developed by the company, China Nuclear Power Research and Design Institute and China Nuclear Power Engineering Co., Ltd. on September, 2017, China General Machinery Industry Association presided over the review meeting of the design scheme and qualification test outline of the main feedwater control valve, nuclear secondary electric gate valve, stop valve, control valve and check valve of the megawatt pressurized water reactor nuclear power plant jointly developed by Shanghai First Nuclear Valve Co., Ltd., China Nuclear Power Research and Design Institute and China Nuclear Power Engineering Co., Ltd. respectively

expert leaders from China General Machinery Industry Association and China Nuclear Power Engineering Co., Ltd. participated in the review meeting. The participating experts and representatives listened to the reports made by the research and development unit, consulted relevant documents, and after discussion and inquiry, It is considered that the design drawings, test outline and documents provided for review are complete and meet the review requirements; The design structure of the prototype is reasonable, the material selection is appropriate, and the performance parameters and structural dimensions meet the requirements of the assignment and relevant standards; The strength calculation, stress analysis, seismic analysis and flow coefficient analysis and calculation are completed, which effectively verifies the rationality of the prototype design. The selection of the prototype is representative, and the test items, sequence and main contents of the qualification test program meet the requirements of ASME and ultimately point out that the car interior needs to give potential users and car owners good perceived quality qme-1 and the requirements of the development mission statement

the expert group unanimously agreed to pass the review of the design and qualification test program. (according to Shanghai first nuclear valve)
