Background of the fourth generation nuclear power plant

The energy structure dominated by coal-fired power generation has brought great challenges to the ecological environment of China. 20 131since mid-October, there has been a large-scale haze weather in the central and eastern regions of China, and it is urgent to adjust the energy structure and develop clean energy.

Huaneng Group said that the site of Huaneng Shidaowan Nuclear Power Station has unique natural conditions, and it is one of the few excellent coastal sites in China that have been fully demonstrated and have the conditions to develop and build a large-scale nuclear power base. Supporting facilities such as construction water, electricity, roads, training center and living quarters have been built here, and the comprehensive office building has also been put into use. Large transport terminals, seawater intake and drainage projects, emergency command centers and other facilities are also under overall planning.

Zhang said that at present, the research and development of key technologies of Shidaowan Nuclear Power Station has been completed, and seven major nuclear island equipment manufacturing and supply contracts, such as reactors, pressure vessels and steam generators, have been signed, and the fuel assembly prototype production line has been put into trial production smoothly, creating good conditions for demonstration project construction.

According to the national policy of giving priority to the development of coastal nuclear power, Huaneng Group made an overall plan for Shidaowan site in order to make full use of the superior resources and supporting conditions of the site. In addition to a high-temperature gas-cooled reactor nuclear power unit, it is planned to build four million-kilowatt PWR nuclear power units and a large-scale advanced PWR demonstration project, CAP 1400. At present, the preliminary work and construction preparation of PWR expansion project have basically ended, and it is ready to start construction at any time.
