Within two months, crews at the Fuquing nuclear power plant in the Fujian province of China have installed all three of Unit 5's steam generators, the China National Nuclear Corporation (CNNC) said on Monday.
The first of the enormous steam generators for the Hualong One reactor project, designed by China Nuclear Power Institute and built by Dongfang Electric, was installed on Nov. 10, 2017. The second was hoisted into place on Dec. 24. It took just under two months for crews to complete the three installations, hoisting the final 365 metric tons steam generator into place Jan. 8. It was placed on a horizontal gantry about 55 feet above ground and then shifted to a vertical position with use of tool custom-designed for the occasion, the World Nuclear Association reported.
The Hualong One model is the next generation CPR1000 Pressurized Water Reactor that borrows design features from the French 900 MWe three-loop cooling reactor, but upgraded to a 1000 MWe capacity (1080 gross MWe). It also represents the merging of two competing Chinese deigns, one in development by CNNC and the other designed by China General Nuclear. Authorities in Beijing, in 2012, however, ordered the companies to work together to create a unified design that would streamline design approval, supply chain, construction and other factors.
The Hualong One model is also slated for export. Last November, the Office for Nuclear Regulation in Britain said the model had passed the first critical step in a regulatory process aimed at approving the use of Hualong One reactors in Britain. The first step was to complete a checklist of readiness for the application to move forward through the regulatory review in the U.K.
The Fuqing power plant is not the only Hualong One project. Construction of the same model is underway for Fuqing's Unit 6 with two additional projects underway at the Fangchenggang nuclear power plant in Guangxi province, a CGN project.
Units 5 and 6 at Fuqing began in May 2015 and December 2015, respectively. The first and second Hualong One units at Fuqing and Fangchenggang are expected to be completed by 2019 and 2020, respectively, for the two concurrent projects.
