The entire operation on Sunday was live-streamed as the dome was hoisted to a height of 70 metres before being put in place at 19:00 local time.
The dome is designed to ensure the integrity and airtightness of the reactor building and the company said it marked the project's move from the civil construction stage to the equipment installation phase.
The Taipingling plant will eventually have six Hualong One reactors. The construction of the first and second units began in 2019 and 2020 respectively.
Yan Shaohua, deputy general manager of CGN's Huizhou Nuclear Power Company, was reported by China News Network as saying dozens of drills had been carried out in advance and the team had "used intelligent nuclear power construction technologies such as Building Information Modeling to perform animation simulations on the hoisting process control, find hoisting difficulties in advance and formulate solutions to ensure … a successful hoisting."
CGN said Taipingling will provide clean energy for the sustainable economic development of the Guangdong-Hong Kong-Macao Greater Bay Area. Once all six Hualong One units are completed, its annual power generation will be some 50 billion kWh, CGN said and will "provide a steady stream of clean energy for the sustainable economic and social development of the Guangdong-Hong Kong-Macao Greater Bay Area" and reduce CO2 emissions by 41.6 million tonnes per year.
