Two stainless steel steam generators have been installed at unit 3 of the Barakah NPP under construction in the United Arab Emirates. The steam generators, manufactured in South Korea by Doosan Heavy Industries, took four years to make. The Emirates Nuclear Energy Corporation (Enec) said that, over the next six months, further piping connection work will take place to connect unit 3's steam generators to the reactor pressure vessel (RPV), turbine generators and condenser. The RPV was installed at unit 3 in July. Enec said construction of unit 3 is now over 54% complete. Enec awarded the $20bn contract for construction of the four-unit NPP in December 2009 to a consortium led by The Korea Electric Power Corporation (Kepco). The four APR-1400 reactors are being built at Barakah, 50km from the town of Ruwais. Overall construction is now almost 68% complete, Enec said. Unit 1 is scheduled to start up in 2017, with the other units following at yearly intervals. The four reactors are expected to provide about 25% of the UAE's electricity with an annual saving of some 12mt of greenhouse gas emissions.
