The successful development of China's nuclear power plant fixed frequency water-cooled centrifugal chillers

China's independent research and development with the world's advanced level of third-generation nuclear power plant with fixed-frequency water-cooled centrifugal chillers (National Science and Technology Major Project) on November 7 in Chongqing by the National Energy Board commissioned by the China Machinery Industry Federation organized scientific and technological achievements assessment . The expert group unanimously determined that all the indicators of this unit meet or exceed the requirements of special research and development. The unit has been successfully developed and the technical performance has reached the international advanced level. Its main performance is even superior to the international advanced level and can be directly used in nuclear power projects. This marks the founding of China's large-scale refrigeration equipment in the field of nuclear power to the next level. Re-pass the Group Nuclear Products Field Identification Society. According to the reporter of China Industry News, the frequency-set water-cooled centrifugal chiller plant of nuclear power station is a sub-project of "major advanced pressurized water reactor and high-temperature gas-cooled reactor nuclear power station" major national special scientific and technological research project of the third generation of nuclear power technology in China. The responsibility of this special project The main support unit is Chongqing General Industry (Group) Co., Ltd. (hereinafter referred to as "Relong Group"), which successfully developed China's first centrifugal chiller in 1964. Due to the demanding safety requirements of nuclear power plants, the associated cooling equipment is also extremely complex and demanding in terms of design requirements. "From the beginning of this task, I knew the importance of this topic and the technical difficulties in completing this topic." According to the reputable group technicians, unit research and development started from January 2014 and the company's technology elite was Integration formed a special project team, and the State Nuclear Engineering Co., Ltd., together with the Shanghai Power Generation Equipment Design Institute, Shanghai Nuclear Engineering Research and Design Institute of experts conducted a full discussion. In a period of 1 year and 10 months, the project team has repeatedly optimized nearly 20 kinds of programs and solved a large number of core technologies such as compressor aerodynamic design, heat exchanger, structure and system design and key technologies, manufacturing and quality control After the development program has been unanimously approved by all experts, the final one-time through the program design, one-time smooth production pass, one-time pass the project acceptance, and access to accreditation expert group spoke highly of. National science and technology major projects, by Chongqing General Industry (Group) Co., Ltd. developed China's third generation nuclear power plant with fixed frequency water-cooled centrifugal chillers.
