The operation to raise the dome from the ground and place it on top of the containment building began at 9.06am on 12 June. In an operation taking some 76 minutes, the dome - measuring 37 metres in diameter and 11 metres in height and weighing about 180 tonnes - was successfully located in position, plant constructor China Nuclear Engineering and Construction Corporation (CNEC) announced yesterday.

Six units are planned for the Yangjiang site in China's Guangdong province by China General Nuclear. The first four units are 1080 MWe CPR-1000 pressurized water reactors, with units 5 and 6 being ACPR-1000s. Unit 1 entered commercial operation in March, while unit 2 began commercial operation earlier this month.

First concrete for unit 5 was poured in September 2013, with that for unit 6 following three months later.

All six reactors should be in operation by 2019, producing a grand total of around 6100 MWe.
