A dome has been installed on the containment building of unit three at the Fangchenggang nuclear power plant in Guangxi Zhuang Autonomous Region in south China, May 23.

The addition of the dome shows the construction project has now entered into a new phase of development in which the equipment is installed. Unit three uses Hualong One technology, a domestically developed third-generation reactor design concept.

Sources say the unit is almost 90 percent homemade, and showcases a combination of Chinese technologies in design, construction, testing and operation.

The dome was added eight days ahead of time, demonstrating China's orderly abilities in building the domestically developed reactor, as well as the capability of its builder China General Nuclear (CGN), said chief director of the project.

CGN has built many projects using Hualong One technology in Central and Eastern Europe, Africa and Southeast Asia in recent years, and has also propelled mass construction of such projects within China.

Two units at the Fangchenggang nuclear power plant are already operational. They alone provide 15 billion kilowatt hours of electricity per year for the Beibu Gulf Economic Zone.

CGN chairman He Yu said exporting a Hualong One nuclear plant will help 5,400 Chinese manufacturing enterprises, which in turn will elevate the influence of Chinese manufacturing and intelligent manufacturing.
