In a blow for the nuclear energy industry, South Africa's power utility Eskom said Friday it had decided against building a second nuclear power plant, citing the "magnitude of the investment", Dpa reported. A consortium led by French nuclear giant Areva and US firm Westinghouse had been vying to build the twin-reactor plant, which would have given Eskom another 3,000-3,500 megawatts of generating capacity, around a tenth of its current installed capacity. A subsidiary of Areva previously built South Africa's first and only nuclear power station at Koeberg in Cape Town. "We note Eskom's decision. We're disappointed of course," Serge Lafont, chairman of Areva South Africa told Deutsche Presse-Agentur dpa. "We wait to see what the country will want."
