Workers have finished concreting the containment building dome for Unit 3 of the Changjiang nuclear power station in Hainan province, southern China, the China Nuclear Energy Association (CNEA) said.
The association said the milestone means the plant is now ready for hot functional testing, which will verify the operation of reactor components and systems before fuel loading.
Changjiang-3 is a domestic Hualong One, or HPR1000, pressurised water reactor (PWR) unit with a gross design capacity of 1,200 MW. Construction began in March 2021.
