BUCHAREST (Reuters) – Romania received six binding bids for the license to build the third and fourth nuclear reactors at its Cernavoda power plant on the Danube River, the plant’s operator Nuclearelectrica said yesterday. The bidders comprise Belgium’s Electrabel, Italy’s Enel, Spain’s Iberdrola, Czech CEZ, a Romanian unit of Arcelor Mittal and Germany’s RWE. The investment is estimated at around -2.2 billion. Romania aims to create a partnership between private investors and state-owned Nuclearelectrica. The European Union newcomer plans to boost nuclear-generated electricity with the two nuclear reactors expected to go on stream by 2015 and plans for a second power plant later. Work at the Cernavoda plant, designed to have five reactors, began 30 years ago. The plant’s first unit went on stream in 1996, while the second nuclear reactor entered commercial use this month.
