On August 28th, China's first self-designed and manufactured second-generation plus millions of kilowatt-class nuclear steam generators was successfully manufactured at the Shanghai Electric Lingang nuclear power industry manufacturing base.
This is the top nuclear island facility of the nuclear power plant contracted by Shanghai Electric for the first phase of Liaoning Hongyanhe Nuclear Power Plant, and also the first million-kilowatt steam generator that Shanghai Electric completed and completed at Lingang Nuclear Power Industrial Base. This steam generator has a total length of 21.7 meters, a total weight of 345 tons, a maximum diameter of 5.5 meters, and is equipped with tens of thousands of fine parts such as U-shaped tubes.
The steam generator is one of the most critical main equipments of a nuclear power plant. In the domestic nuclear power market, Shanghai Electric maintains its long-term share leadership position. The intensive supply capacity of its nuclear power nuclear island equipment ranks first in the country, and the supply contract for nuclear power nuclear island equipment undertaken in recent years has reached more than 24 billion yuan.
The first phase of Liaoning Hongyanhe Nuclear Power Project was jointly constructed by China Guangdong Nuclear Power Group Co., Ltd., China Power Investment Group Co., Ltd. and Liaoning Province. This project is the first nuclear power project approved by China during the “Eleventh Five-Year Plan†period. It is also the first nuclear power plant in the northeast region and the largest energy construction project to date. Once completed, the annual power generation will reach 30 billion kWh. At present, Dalian City has twice the annual electricity consumption.
The million-kilowatt steam generator project contracted by Shanghai Electric Nuclear Power Equipment Co., Ltd. was approved to start work on January 8, 2008. Tube-sheet assemblies began to be manufactured on April 24 and was completed in August 2010. In the process of independent development, Shanghai Electric Nuclear Power Equipment Co., Ltd. broke through the restrictions originally provided by the foreign parties for the procurement of complete sets of raw materials, mastered the self-purchasing techniques for the full set of raw materials required for product manufacturing, and innovated the nuclear power project management system to establish a set of Adapt to the project management system of nuclear power products.
The successful manufacture of this evaporator means that Shanghai Electric Nuclear Power Equipment Co., Ltd. has completely possessed the independent manufacturing capabilities of the second-generation and multi-million-ton steam generators, and achieved product manufacturing energy levels from 600,000 kilowatts to 1 million kilowatts. The major breakthrough has also accumulated rich experience for the company's follow-up of more than 50 nuclear power steam generators of various technical routes.
In order to implement the national strategy and develop the nuclear power industry, Shanghai Electric is investing an additional 840 million yuan in capacity expansion and technological upgrading in the field of nuclear power. After the completion of the second phase of capacity expansion of the Lingang Nuclear Power Industry, the existing nuclear island equipment integrated manufacturing capacity will be upgraded to an annual output of 4 to 6 sets of steam generators, pressure vessels and regulators, with 8 to 10 sets of reactors. Components and control rod drive mechanism.

Shanghai Electric is one of the earliest enterprise groups engaged in the manufacture of nuclear power equipment in China. In the field of nuclear power equipment manufacturing, it possesses the most professional manufacturing base with the best domestic capabilities, complete supply capacity, rich manufacturing performance, perfect management system and excellent talents. Shanghai Electric provides pressure vessels, steam generators, stack internals, control rod drive mechanisms, regulators, nuclear-grade main pumps, nuclear-grade pump valves, nuclear-grade vessels, circular cranes, loaders and turbine generators, Key equipment such as steam and water separation reheaters, high and low pressure heaters, and various types of Auxiliary Equipment, such as nuclear islands and conventional islands, as well as nuclear-grade large-scale castings and forgings, instrumentation, and instrumentation control systems, and other nuclear power products.
The function of the steam generator is to transfer the heat of the heat carrier in the reactor so that a steam with a certain pressure can be used to operate the steam turbine. The steam generator is connected to the reactor pressure vessel and its heat carrier is radioactive. The generated steam dryness requirement is higher than 99.9%, directly affecting the power and efficiency of the power plant. At the same time, the steam generator plays a role in blocking heat-generating agents while performing heat exchange and is critical to the safety of nuclear power plants. Therefore, the requirements of the steam generator have a grade one safety rating, a type I seismic proof grade, a grade one specification grade, and a Q1 grade quality requirement. The materials and manufacturing high-tech content are among the highest in contemporary manufacturing.
