Concrete Dome Completed on Barakah Nuclear Unit 2 Project

The Emirates Nuclear Energy Corp. (ENEC) completed construction of the concrete dome for the Unit 2 reactor containment building (RCB) at the Barakah nuclear power project in the United Arab Emirates (UAE).

The dome is the final structural component of the RCB, which now measures more than 70 meters in height. The dome measures 51.4 meters in diameter, 24 meters in height and weighs approximately 9,000 metric tonnes. It was built in nine stages.

The RCB houses the reactor and is extremely robust in its design with thick concrete walls and heavy reinforcing steel. The next phase of work on the RCB involves the installation of the containment post tensioning system, which is used for pre-stressing the concrete structure, followed by a three-month structural integrity test.

ENEC’s team works closely with Korea Electric Power Corp. (KEPCO), Hyundai/Samsung joint venture and Seoyong Construction throughout construction of the RCB.

Unit 1 is now more than 87 percent complete, Unit 2 is 68 percent complete, Unit 3 is 47 percent complete and Unit 4 is 29 percent complete. Overall, the four reactors are more than 62 percent complete and are set to be completed by 2020.
