Nuclear energy is a new energy source that we are paying close attention to and researching and developing energetically in recent years. Its energy is huge and its use is extensive. Shanghai's major technology and equipment center recently developed a nuclear island single-seat control valve made a new breakthrough. On April 25, Shanghai Economic Commission organized the relevant experts in the industry to conduct project acceptance in Shanghai Seven Instrument Factory Automation Instrumentation. Representatives of Shanghai Nuclear Power Office, self-instrumental shares and experts from Shanghai Polytechnic University, China Central Plains Foreign Engineering Company, Nuclear Qinshan Associates Ltd. and China Guangdong Nuclear Engineering Co., Ltd. participated in the inspection meeting. The project inspection and acceptance group believes that the nuclear 2-stage pneumatic control valve designed and manufactured by Shanghai Automation Instrument 7 Factory has filled the gap in China and fully complies with the RCC-M nuclear two-level specification and can be applied to PWR nuclear power plants. Unanimously agreed that the project passed the acceptance. Nuclear island common single-seat control valve DN25 female valve development is based on the Hongyanhe nuclear power project as the basis, RCC-M as the standard. The project is jointly undertaken by Shanghai Instrument Automation Instrument Co., Ltd. and Shanghai Jiao Tong University Nuclear Power Technology and Equipment Research Center. Song Zhiping, director of Autonomous Instrument Plant Seven, is the project leader. Seven meters from the plant responsible for the overall program planning, prototype design, manufacture, development prototype test acceptance outline. Shanghai Jiao Tong University is responsible for the seismic analysis of the prototype, fluid flow analysis and reliability analysis. Commissioned by the National Industrial Automation Instrumentation Products Quality Supervision and Inspection Center authorized Shanghai Instrument Instrumentation Automatic Control System Test by the prototype test and witness. The conclusion is: after the completion of the basic performance test and identification test of the test sample according to the "Acceptance Test Outline", the structure and workability of the sample remain intact and meet the requirements of test basis. With the success of this "nuclear island common single-seat control valve DN25 female valve," the successful development of the cause of the valve has brought a huge surprise, but also marks the self-instrumentation seven plants with independent research and development of nuclear-level products, the ability to more nuclear Level control valve localization laid the foundation is a significant breakthrough.
