Authorities say Russia's Atomstroiexport has become the only bidder to construct Turkey's first nuclear power plant, and five other firms have refrained from submitting bids, AP reported. Haci Duran Gokkaya, the head of Turkey's state-run electricity company, says authorities will evaluate the bid and it is not clear yet if the tender will be canceled. The reason for failure to attract more bidders by the deadline Wednesday is not known but some firms complained that they needed more time to prepare. Activists often protest against plans to build the plant on the Mediterranean coast. Turkey also plans to build a second nuclear plant later, near the Black Sea port city of Sinop.
