Harbin Auto Continues to Push Self-determination of Nuclear Power Equipment Autonomy

Harbin Steam Turbine Factory Co., Ltd. (hereinafter Harbin Steam Turbine Co., Ltd.) recently broke news. The company has fully mastered the world's most advanced nuclear power turbine design key technologies. The preliminary design of its independently developed CAP1400 nuclear power turbine has been completed. At this point, Kazakhstan Automobile achieved a nuclear power turbine development from 650MW to 1250MW, and then to more power across.

It is understood that the company has achieved remarkable results in the first year of the “Twelfth Five-Year Plan”. This year, 51.82% of the year's plan for the steam turbine of the power plant was completed, and the total industrial output value of the company was 52.48% of the annual plan. The total profit completed is the annual plan. 50.66% of the total. Among these, the company has shown good advantages in the development of three-generation nuclear power turbines.

Yang Qiguo, chairman and general manager of Harbin Auto, who has surpassed self-promotion CAP1400, said that due to the impact of the nuclear accident in Fukushima, Japan, China has decided to suspend the approval of new nuclear power projects, but the demand for nuclear power development is objective and future development. More emphasis will be placed on its security. In order to develop nuclear power technology, as early as the "10th Five-Year Plan" period, Kazakhstan Automobile developed a technical reserve for the development of higher-level products while developing a 650MW nuclear power turbine. Successively carried out research on the key technologies of a million-level nuclear turbine, completed design schemes for full-speed and half-speed steam turbines, and plans for full-speed and half-speed steam turbine machining and quality assurance; and jointly researched and developed CAP1400 rotors for complete forging with China First Weapon and Japan JSW. Self-developed 1200 mm, 1800 mm long blades; Completed supplementary research topics in PWR turbine design, technology, materials, etc., and completed the program design of 1000MW full-speed nuclear turbine. At the same time, a complete nuclear power quality assurance system has been formed, laying a solid foundation for the design and manufacture of nuclear power turbines of the million kilowatts level.

The CAP1400 nuclear power station was included in the “12th Five-Year Plan” key scientific research project by Kazakhstan Auto. Since the beginning of this year, the company has carried out reinvention on the basis of digesting and absorbing China’s introduction of third-generation nuclear power technology. The relevant experts fully affirmed the project design plan of Kazakhstan Auto.

Independent innovation to build China's nuclear power brand As early as 1992, Harbin Electric fully utilized and absorbed the related technology of American Westinghouse Electric Company and successfully developed the HN64.2-6.41 (650MW) nuclear power turbine. In December 1999, China’s first nuclear power unit was upgraded from 300 MW to 650 MW. The Qinshan nuclear power plant of the second phase of the second phase of the company’s 650 MW nuclear power turbine, which was responsible for the transition from the test and evaluation power station to the commercial power station, was completed. The first unit was completed in April 2002. On the 17th, the company passed the 168-hour test run and was officially put into commercial operation; on the 1st of June 2003, the non-nuclear steam reformed successfully on the 2nd unit, setting a record for the localization rate of high-power nuclear power turbines at that time. The two units successively passed the review and appraisal commissioned by the China National Machinery Industry Federation commissioned by the National Development and Reform Commission and won the National Major Technical Equipment Achievement Award and the National Key New Product Award.

Thanks to the excellent performance of the two 650MW nuclear power turbines of Qinshan Nuclear Power Phase II, Kazakhstan Auto once again won the manufacturing contract of two 650MW nuclear power turbines for the conventional island of Qinshan Phase II expansion project. It was manufactured in 2008 and officially put into operation on August 1, 2010. Commercial operation.

So far, Harbin Auto has provided four 650MW nuclear power nuclear turbines for Qinshan Nuclear Power Phase II and Phase II expansion projects. Among the 11 major assessment indicators, 9 have reached the world advanced level. Especially in the manufacture of the two units in the second phase of the expansion project, the design route of “based on independent innovation and building an independent brand” has emerged, and the main equipment has fully realized localization.

In 2010, Kazakhstan Auto assumed the task of providing two improved 650MW nuclear power turbines for the Changjiang Power Station in Hainan Province. The main parameters required for the two units provided by this time are basically the same as those of the No. 1 and No. 2 units of Qinshan Nuclear Power Phase II. However, the performance of the unit has been further optimized. The safety level and economic level of the unit have been further improved compared with the second phase of Qinshan Nuclear Power.

New breakthroughs have been made to overcome the difficulties of the third-generation nuclear power technology. According to the “National Nuclear Power Development Thematic Planning (2005~2020)”, the construction of the third-generation PWR first-stage project with Chinese brand started in 2010 and the third batch of construction after 2015. Replacing nuclear power plants on behalf of water reactors will become the overall deployment of China’s nuclear power generation models after 2020, and will set technical development targets on three generations of nuclear power technologies.

AP1000 is the result of the research that Westinghouse Company has always insisted on. At the end of 2006, China and the United States signed a memorandum of cooperation on cooperation and technology transfer for AP1000. In accordance with the instructions of the relevant national ministries and commissions, from the beginning of 2005, Harbin Electric Group Co., Ltd., Harbin Electric Co., Ltd. (former Harbin Power Equipment Co., Ltd.) and Kazakhstan steam leaders cooperated with the third-generation nuclear power CI (conventional island) The matter was extensively contacted and negotiated. It was finally determined that a joint venture with Mitsubishi Corporation, which controls the third-generation nuclear power technology of American Westinghouse’s AP1000, will participate in the bidding for the Sanmen and Haiyang nuclear power plants.

On September 28, 2007, at the signing ceremony of the equipment supply and design contract for the conventional island equipment for the first phase of the nuclear power plant of China Nuclear Power Group's Sanmen nuclear power plant held in the Great Hall of the People in Beijing, Harbin Electric Power Corporation and Mitsubishi Corporation of Japan and Sanmen Nuclear Power Co., Ltd. Signed a three-phase supply contract for conventional nuclear power equipment for nuclear power, marking that it has become the first steam turbine manufacturing enterprise in the country and even the world to enter the third generation of nuclear power, further defending its leading position in the field of domestic nuclear power turbines.

In 2010, Kazakhstan Automobile strategically proposed innovative development models of "big production" and "off-site manufacturing." After a large amount of preparatory work, the company set up a nuclear power office, built a nuclear power equipment branch, and invested in Qinhuangdao and Dalian to build a general assembly base, which has now been fully put into production.

The three generations of nuclear power generating units of the third generation are the first organization of production of the steam turbines. It is very difficult and represents the most advanced manufacturing level of nuclear power in the world. Through the close cooperation and careful organization of the company's various departments, most modules of the world's first three-generation nuclear power condensers have been completed and shipped smoothly on the Qinhuangdao assembly line. In addition, the low pressure heater first tube sheet is processed, and high pressure cylinders, low pressure cylinders and other key components have fully entered the production and processing stage. All of these signals that the company has stepped into a new stage of standardization, specialization, and mass production in the manufacturing of millions of nuclear power conventional island equipment, and has continuously achieved new breakthroughs.

After market promotion and bidding, Harbin Auto has now won 12 supply contracts including Sanmen, Haiyang, Xianning and Tianwan.

Focusing on the future, we will make every effort to build a quality project affected by the leakage of the nuclear power plant in Fukushima, Japan. The development of short-term nuclear power will be slowed down to some extent. However, Kazakhstan Auto has full confidence in the future development of nuclear power: In the long term, due to the impact of resources and environmental pressure, China's policy of developing nuclear power will not change, and the development mode will be transformed from vigorous development to safe and efficient development. With the increasing emphasis on the safety of nuclear power, the future market prospects of the third-generation nuclear power AP1000 featuring “non-active safety” will be further improved.

During this period, Kazakhstan Automobile quickly improved the nuclear power production and manufacturing system, formulated a complete "Nuclear Power Quality Assurance Program", and compiled nine special procedures for document control, non-conformance control, auxiliary material control, material procurement, and outsourcing control. Controlling the design, procurement, and production processes, and further accelerating the digestion and absorption of imported technologies, investing more energy in quality assurance, and doing its utmost to ensure that Sanmen, Haiyang, and other third-generation nuclear power projects are under construction and build quality products. engineering. In strict accordance with the requirements of nuclear power quality assurance system to organize production, increase the monitoring of the entire process to ensure the quality and safety of the production process and key components.

At the same time, Harbin Automobile vigorously promoted the construction of “nuclear culture” throughout the company and even the related supplier companies, integrating the “four common things” and “four emphasis” of nuclear power into the entire production process.
