"Hualong-1" is a major achievement made by China in independent innovation of nuclear power. Its safety is comparable to that of the mainstream three generations of the world and its economy is more advantageous. It has become a "national business card" that goes hand-in-hand with high-speed rail. According to news reports from authoritative media recently, the first generator of "Hualong-1" nuclear power project has officially passed the "type test" and all the indicators have reached and surpassed the design requirements, marking China's "Hualong No.1" Developed successfully. Another step forward in nuclear energy technology "Hualong One" first generator successfully landed According to the Xinhua News Agency, November 6, the first generator of the "Hualong-1" nuclear power project passed the "type test" on the 6th by Dongfang Electric Group Dongfang Electrical Machinery Co., Ltd., meeting and surpassing the design requirements for all the indicators and marking the " Hualong One "first generator independently developed. This is the second CAPIVO nuclear energy turbine generator successfully developed in the Dongfang Electric, China's third generation nuclear power equipment completely independent design and manufacturing capabilities once again leapfrog. The successful development of the generator, in order to create a "China Nuclear Power" brand, cast a great example of the country has taken a solid step forward. "Hualong No.1" first nuclear power generator independently developed by Dongfang Electric will be applied to CNR Fuqing Nuclear Power Station Units 5 and 6. "Type test" results show that the bearing vibration requirements of not more than 50 microns, the measured minimum is only 3.9 microns. Vibration of other components is also much lower than the design requirements. After more than 30 tests, the "Hualong-1" nuclear generator passed the real four-day rotation test and the performance indicators met and exceeded the requirements of the contract and standards. The unit efficiency, vibration value and temperature rise were all excellent. In the introduction of technology units, reached the world advanced level. Hualong No.1 has a number of design innovations in terms of calculation methods, structural layout, structural materials, and insulation technologies. It adopts the independently developed electromagnetic calculation program, the new ventilation and cooling technology, the insulation system, the static excitation system, the integral stator structure, etc. , Generator efficiency of 99%. As the national brand of "China Nuclear Power", "Hualong No.1" has been given the implication of "rejuvenation of China and giant dragon takeoff" and placed high hopes on China's independent nuclear power technology. It is the main project to push forward the "going global" of nuclear power in China. In terms of design innovation, Hualong No.1 proposed the safety design concept of "combination of active and passive operation" and set up perfect accident prevention and mitigation measures. The safety indicators and technical performance of the company have reached the advanced level of the international third generation nuclear power technology, Is the safest PWR nuclear power model with complete independent intellectual property rights. In April 2015, the executive meeting of the State Council decided to approve the construction of the "Hualong-1" third-generation nuclear power demonstration unit and promoted them on the lines of No. 5 and No. 6 units of Fuqing NPP and units No. 3 and No. 4 of Fangchenggang Nuclear Power Plant in Guangxi. In May, Unit 5 of Fuqing NPP officially started its operation and took the lead in using the "Hualong No.1" technology. The world's first reactor demonstration project "Hualong I" was put on the ground in Fuqing. "Dragon" Kyushu. Fuqing Nuclear Power Station is located in Fuqing City, Fujian Province, planning and construction of 6 million-kilowatt pressurized water reactor nuclear power plant units, construction in two phases. In the first phase of the power plant provided by Dongfang Electric, all four nuclear steam turbine generators have excellent performance and are safe and reliable in operation. In 2013, Dongfang Electrical Machinery also undertook the independent research and development of "Hualong-1" nuclear-powered turbogenerators of units 5 and 6 Glorious task, to help "China's nuclear power" to shine the world. Nuclear energy turbine generator is the core equipment of large-scale nuclear power plant and is the key equipment to convert nuclear energy into electrical energy. With years of experience in the research, design and manufacture of nuclear turbine generators, Dongfang Electrical has devoted itself to studying the technology of the third generation of nuclear power equipment in China and successfully solved a number of technical manufacturing challenges. In the completely independent research and development of a new generation of nuclear turbine generators A number of innovative achievements have been made. The "Hualong-1" nuclear-powered turbo-generator developed for Fuqing NPP Unit 5 and Unit 6 has a unit capacity of 1,200 megawatts. The parameters are high, its capacity is large, the structure is complex, and the technical difficulty of designing and manufacturing is also higher. In order to ensure the safety, efficiency and excellent performance of the self-developed "Hualong-1" nuclear-powered turbo-generator, Dongfang Electrical Machinery has conducted rigorous control over every aspect of the design from the beginning of design to the completion of manufacture. In the research and development of the generator, based on the independent research and development platform, Dongfang Electric made systematic research on the electromagnetic, mechanical, insulation and ventilation technologies of the generator. By using the combination of the classical calculation method and the finite element analysis, The design and development of the overall machine and key components ensure advanced, reliable and safe. Dongfang Electric carried out a number of design innovations in terms of calculation, structural layout, structural materials, and insulation technology. The self-developed electromagnetic calculation program, the new ventilation and cooling technology, DeaMica insulation system and static excitation system, Stator structure, low welding sensitivity of high-strength alloy steel, and the full use of three-dimensional design platform for structural design, effectively improve the product design accuracy, the generator performance parameters to the world advanced level, of which the efficiency of 99%; used on the generator New methods, new structures, new materials, Dongfang Electric carried out a series of process technology research, experimental verification, to ensure product reliability.
