Dome Placed For Unit 4 At Barakah NPP

The Emirates Nuclear Energy Corporation (ENEC) announced Tuesday that the Reactor Containment Building dome for Unit 4 at the yet-to-go-commercial Barakah Nuclear Energy Plant had been successfully set in place, marking another milestone for the country's first commercial nuclear power project.

Barakah Unit 4 domeThe reactor's Coolant Loop, pipe welding and "the setting of key equipment" have also been completed at the facility located in the Al Dhafrah region of Abu Dhabi, ENEC said.

The dome is the final structural component of the RCB, which now measures around 70 meters in height. The RCB houses the nuclear Reactor Vessel (RV), Steam Generators and other major components. Built out of concrete and heavily reinforced steel, RCBs are ranked among the strongest structures in the world. The successful and efficient completion of welding of the RCL, which plays a key role in transferring heat from the Reactor Vessel (RV) to the Steam Generators, is another key step towards the start of major testing for the systems of Unit 4, ENEC noted.

Construction of last unit of the plant commenced in 2015, and it "continues to benefit from the lessons learned and experience gained by the teams responsible for the construction of the other three units," said Eng. Mohamed Al Hammadi, ERNEC Chief Executive Officer.

Al Hammadi said construction for Unit 4 currently standing at 67 percent complete. "The next phase for the unit will be to start the transition from construction to testing and commissioning," he said. He also praised the "exceptional partnership" between ENEC and its Prime Contractor and Joint Venture partner, the Korea Electric Power Corporation (KEPCO, operating "in combination with the dedication and expertise of our UAE Nationals and international experts."

In addition to the completion of the RCB dome structure and RCL welding, a significant amount of major equipment setting has been safely and successfully completed at Barakah Unit 4.
