Unit will be first of two indigenous Hualong One PWRs at site
The outer steel dome of the nuclear island containment building has been lifted into place at the Lufeng-5 nuclear power station in Guangdong province, southern China, the China Nuclear Energy Association (CNEA) reported.
The dome forms part of the reactor’s containment building, which consists of an inner steel shell and an outer concrete shell. The containment is designed to protect the reactor from external effects and withstand high external and internal pressures and protect against radiation release.
CNEA said the outer steam dome measures about 45 metres in diameter, 13 metres in height and weighs almost 262 tonnes.
Lufeng-5 will be the first of two indigenous 1,116-MW Hualong One, or HPR1000, pressurised water reactor units planned at the Lufeng site.
Construction of Lufeng-5 began in September 2022 and of Lufeng-6 in August 2023. Unit 5 is expected to be connected to the grid in 2028 and Unit 6 in 2029.
Four CAP1000 units are also planned for the site. The CAP1000 is China’s domestic version of the Westinghouse AP1000 design.
