To build a world-class nuclear power brand, Shanghai Electric took a substantial step. On April 10, 2018, the world's first nuclear power plant, Hualong No. 1 nuclear power plant, Fuqing No. 5 unit internals was at Shanghai Electric Shanghai No. 1 Machine Tool Plant. Co., Ltd. shipped. Fuqing No. 5 unit reactor internals equipment was developed by China Nuclear Power Research and Design Institute, and was manufactured by Shanghai No.1 Machine Tool Works Co., Ltd. After 33 months of development cycle, it passed the March 15th, 2018 Acceptance. The first Hualong No. 1 reactor internals equipment successfully achieved localized manufacturing, and the third-generation nuclear power technology of our country's independent intellectual property rights was transformed from the drawings into reality, indicating that Shanghai Electric's nuclear power equipment manufacturing capacity has been upgraded to a new height.
'Hualong No.1' is the independent innovation achievement of China's third-generation nuclear power generation. It has complete independent intellectual property rights, and its localization rate exceeds 85%. It is a landmark project to promote the implementation of China-made 2025, and is also a national new card for 'going out' of China's nuclear power. , Has now become China's focus on the promotion of the international brand on the international stage.
'Hualong No.1' reactor internals are the core reactor 'keel' equipment of the third-generation nuclear power technology 'Hualong No.1' reactor with complete independent intellectual property rights in China. It is composed of 236 categories and 13487 parts, with a height of 11.036 meters and a maximum diameter of 4.188. The meter, weighing about 160 tons, adopts the most advanced, most stringent and globally-highest standard design in the world. Its structural accuracy requirements and manufacturing complexity far exceed those of the second-generation improved nuclear reactor reactor internals such as the M310. Key technologies for its manufacture include: Precision machining, precision welding, precision testing and precision assembly represent the highest level of R&D and manufacturing of nuclear equipment in China's third-generation nuclear power technology. In all reactors, the reactor internals are the key to the key. The large and small equipment on the island is likened to the organs in the body of the 'Hualong I' dragon. The internals of the dragon are enveloping the organs and supporting the dragon's 'keel'. The core of the entire nuclear power operation, The source of inexhaustible power—the nuclear fuel assembly—is installed in the 'keel'. At the same time, this 'keel' must also be a safe 'cage': in the event of an extreme accident, The inner member must be able to effectively prevent the core falls, reducing the impact on the natural environment.
Since the first reactor internals equipment was started and manufactured in 2015, Shanghai Electric Shanghai No. 1 Machine Tool Works Co., Ltd. has captured 71 processes, tests and other difficulties; completed two localization of materials, five welding techniques, and four detection technologies. , 7 technological innovations; obtained 10 invention manufacturing patents, and realized the complete localization of fabrication, processing, assembly, testing, welding and acceptance testing tooling design and manufacturing of Fuqing No.5 internals.
