Large-capacity nuclear power turbine manufacturing technology has achieved a major breakthrough

A few days ago, commissioned by the National Development and Reform Commission, China Machinery Industry Federation organized a special appraisal meeting in Beijing for the first domestic 650,000-kilowatt nuclear power turbine machine manufactured by Harbin Steam Turbine Co., Ltd. for the second phase of Qinshan Nuclear Power Station. The development was evaluated and evaluated.
The No. 1 steam turbine unit of the Taishan No. 2 Nuclear Power Plant is the first 650,000-kilowatt steam turbine unit in China that has been successfully developed based on cooperation between China and foreign countries. In the process of designing and manufacturing this unit, Harbin Auto actively involved foreign advanced technology and combined its own research and development of mature technologies for subcritical 600,000 kilowatts of steam turbines, thereby making the entire unit extremely excellent. Not only the technical performance is excellent, but also fully meets the requirements of the technical specifications. The heat performance of the unit performance test is 9,962kj/kwh, and the maximum guaranteed output is 689,000 kw, which has reached the international advanced level. The unit has been put into commercial operation for more than one year, and the operation is stable. Social benefits are significant. The successful development of this unit indicates that China has made major breakthroughs in the joint design and co-manufacture of large-capacity nuclear power turbines, and it also indicates that China’s equipment manufacturing industry continues to grow and grow. At the same time, it has also accumulated rich energy for China’s self-developed multi-kilowatt nuclear power turbines in the future. experience.
