China's first fully self-developed Nuclear Power Station No.1 reactor nuclear reactor pressure vessel manufactured by China First Heavy Machinery Group Corporation was completed on the 18th and sent to Liaoning Hongyanhe. After testing, all the technical indicators of the equipment meet the requirements, which indicates that the manufacturing of the main equipment of millions of kilowatts of nuclear islands in China is fully domesticated and has the ability to provide complete sets of equipment for the development of standardization, mass production and large-scale development of nuclear power in China. .
Hongyanhe Nuclear Power Station is the first one-kilowatt nuclear power station started construction during China's “Eleventh Five-Year Plan†period, and the first million-kilowatt nuclear power station in Northeast China. It is the key support project for the second-generation nuclear power independent construction in China. In accordance with the requirements of the National Development and Reform Commission, the development of four units in the first phase of Hongyanhe River will basically realize the autonomy of the second generation of improved nuclear power equipment with a kilowatt level.
As a key equipment in PWR nuclear power plants, nuclear reactor pressure vessels are closed vessels that place nuclear reactors and withstand enormous operating pressures. They have the characteristics of high manufacturing technology standards, high degree of difficulty, and long cycle time. They are non-replaceable equipment and must ensure the life of nuclear power plants. It is absolutely safe and reliable during the period.
Since the launch of this project, China has meticulously organized the project as a model product for enterprise restructuring, product transformation, and transformation of economic development methods. It has configured all parties’ superior resources and implemented all aspects in terms of technology research and development, production organization, quality supervision, and schedule progress. Process control ensures that everything is safe.
It is understood that China has established itself as an independent innovation company and has concentrated on its strengths. In the development process, it has produced a large number of industrial and auxiliary tools, conducted a large number of tests and process assessments, and successively conquered the compaction, quenching, and grain refinement of large-scale thick-walled forgings. And the homogeneity, integration of the forging section forming forging, saddle fitting section welding, neutron flux tube hole processing and other technical difficulties, created a number of China's nuclear power equipment manufacturing history, a number of first.
With the rapid development of China's nuclear power industry in recent years, more advanced second-generation and third-generation nuclear power projects have started construction in China. Due to the large amount of demand, large-scale castings and forgings required for key nuclear power equipment have become the bottleneck restricting the rapid development of China's nuclear power industry. Import from abroad is difficult to meet the demand and there are barriers to the introduction of technology, which seriously affects the construction process of China's nuclear power plants.
To reverse this situation, China, as a leading manufacturer of heavy equipment manufacturing in China, has been engaged in research and development of nuclear reactor pressure vessels for many years. It is committed to the development and application of nuclear power products' own technologies and nuclear special technologies, and promotes them in long-term production practices. The localization of nuclear power has accumulated rich experience.
Since 2006, "China's key large-scale manufacturing technology for nuclear power equipment, large-scale castings and forgings," "the development of nuclear power equipment, large-scale forgings," "AP1000 pressure vessel manufacturing technology," and other national key issues have been established, China has a large number of key development tasks. . In accordance with the deployment, it focused on its strengths and focused on the three main lines of scientific and technological breakthroughs, technological transformation, and manufacturing qualification certification. It carried out technical research on localization of key equipment for the second generation of improved and third-generation nuclear islands and continued to make breakthroughs.
At present, China has been at the leading international level in the development of nuclear reactors such as nuclear reactor pressure vessels and nuclear islands.
