China's nuclear power technology to achieve the four major leap: a substantial increase in localization rate

The National Energy Board held a press conference in Beijing on October 31, deputy director of the nuclear power company Qin Zhijun said, 'large-scale advanced PWR nuclear power plant and high-temperature gas-cooled reactor nuclear power plant' national science and technology major projects in the past 10 years, has been established Project 201, approved the central government funds of 13.033 billion yuan to support and promote China's nuclear power in a comprehensive grasp of three generations of non-active nuclear power technology and self-capture with four generations of characteristics of high-temperature gas-cooled reactor technology, key equipment development, basic materials development, nuclear power common technology R & D four aspects to achieve a large leap.

Qin Zhijun explained that the four leaps include: through the introduction of digestion and absorption and re-innovation, quickly grasp the world's advanced non-dynamic design concept, and successfully learn and apply to the CAP1400 and 'Hualong a' design, greatly enhance the safety of nuclear power plants In the high temperature gas-cooled reactor as the representative of the four generations of nuclear power technology, through the demonstration project traction, captured a series of technology, equipment problems, industrial applications have come to the forefront of the world, a nuclear power to go out of a business card The

Three generations of nuclear power plant pressure vessels, steam generators, main pipeline and a large number of heavy equipment to achieve the localization of the main motor shielded motor, digital instrumentation systems, blasting valves and other core equipment have been completed prototype manufacturing, high temperature reactor control rod drive mechanism, fuel Loading and unloading system has been achieved supply, so that our country with an annual output of 6 to 8 sets of nuclear power equipment manufacturing capacity, the third generation of nuclear power localization rate of relying on projects from 2008 to 30% to now more than 85%.

High-temperature reactor fuel components have been industrial production; nuclear grade welding material developed successfully, changed the nuclear power welding materials Long-term dependence on the import situation; built the first from the sponge zirconium to the finished product tube, plate, bar, strip of the complete production line. Base material developed to make up the short board, fill the blank.

In the reactor core and safety analysis of key technology research, serious accident mechanism and phenomenological research, nuclear power plant key material performance research and other common technology to carry out in-depth research, the construction of a number of leading international large platform and test facilities for China's new nuclear power Model design, continuous improvement of nuclear power innovation and research and development capabilities to provide a guarantee.
