The Emirates Nuclear Energy Corporation (ENEC) has installed the Unit 2 Steam Generators at the Barakah nuclear power facility
The two SG units, made of stainless steel, have been manufactured at South Korea’s Doosan Heavy Industries, which is part of ENEC’s Korean Prime Contractor Consortium. The generators were shipped to Barakah in Abu Dhabi and installed in the Unit 2 Reactor Containment Building.
ENEC CEO Mohamed Al Hammadi said, “This is an important milestone in the continued progress and delivery of ENEC’s second unit, which is scheduled to come online in 2017. As with all of our work at Barakah, I am proud to see the team continue to deliver these significant achievements with safety, quality and performance as top priority at all times.”
The steam generators act as heat exchangers, where the water carrying the heat generated from the nuclear reactors is used to convert demineralised water into steam. This mechanism keeps the water in the reactor and turbine separate. The steam generated is then used to spin a turbine that drives a generator to produce electricity. Each of the steam generators contain numerous tubes that carry heated processed water at high pressure. These tubes are made of an alloy composed of nickel, chromium and iron, making them corrosion-resistant even at high temperatures, revealed ENEC.
ENEC officials have also stated that additional piping connection work will take place over the next six months to connect the generators to the Unit 2 Reactor Vessel, turbine generators and a condensor, in order to allow water and steam to pass in and out as needed for the production of electricity.
