Hubei Daily News (Reporter Zhou Chun, Correspondent Li Xin) On the morning of June 28, as the first tank of concrete began to be poured, China Nuclear Industry No. 22 Construction Co., Ltd., a central enterprise in Hubei, (referred to as " China Nuclear Industry No. 22") The second phase of the national key civil engineering project undertaken by the second company ") - the Sanmen Nuclear Power Plant phase 2 project sounded the clarion call to start construction.

Sanmen Nuclear Power Project is located in Sanmen County, Taizhou City, Zhejiang Province. It plans to build six million-kilowatt pressurized water reactor nuclear power units , which will be constructed in three phases. Among them, the first phase of the project officially started on April 19, 2009, and by 2018, Units 1 and 2 of the first phase have been connected to the grid to generate electricity.

It is reported that the civil construction of the first phase of the Sanmen Nuclear Power Plant is also undertaken by CNNC No.22 Company. During the construction period of more than 10 years, CNNC No. 2 Company has invested a total of more than 1,600 management personnel and more than 10,000 workers, successfully completing various civil construction tasks, laying a solid foundation for the final commercial operation of the first phase of the project. The first phase of the Sanmen Nuclear Power Plant won the 2020-2021 National Quality Project Gold Award.

On the same day, the pouring of the raft foundation plate of the nuclear island reactor building of Unit 3 of the Sanmen Nuclear Power Phase II Project began. It is understood that the rated capacity of a single unit of Units 3 and 4 of the second phase project started this time is 1.251 million kilowatts, and the power station has a designed operating life of 60 years. Once completed and put into operation, the Sanmen Nuclear Power Plant will have an installed capacity of 5 million kilowatts and an annual power generation of 40 billion kilowatt hours, equivalent to an annual reduction of carbon dioxide emissions of 30 million tons.

The construction team of CNNC No. 2 Company said that relying on the construction experience of the first phase of the project, the team took the lead in mastering the irregular raft foundation large-volume concrete pouring technology of the Sanmen Nuclear Power Phase I project, the large-area hyperboloid pressure grouting technology in the lower part of the CVBH, and the ultra-high More than 10 key technologies including structural module self-compacting concrete spiral continuous pouring technology, and more than 240 experience feedback items have been organized to summarize, optimize and apply the first phase of the project, which can be continuously used in the subsequent construction of the second phase of the Sanmen Nuclear Power Plant to assist national key projects. The project was built with high quality and efficiency.
