SEOUL (AFP) A South Korea-led consortium on Sunday won a 40-billion-dollar deal to build and operate four nuclear power plants in the United Arab Emirates, the knowledge and economy ministry said. The deal consists of a 20-billion-dollar contract to build four nuclear power plants for the Middle East state, which will lead to another 20-billion-dollar contract to operate them, the ministry said in a statement. The deal marks South Koreas first export of a nuclear power plant and also its single largest overseas construction project in terms of value, it said.
