The company will build and operate the four-reactor nuclear power plant in the Mersin province on Turkey's Mediterranean coast.Before construction begins, an environmental assessment report needs the approval of the Ministry of Environment and Urban Planning.Akkuyu had prepared a 3,000 page-long report assessing all aspects of the project for the ministry.The Akkuyu Nuclear Power Plant is estimated to cost around $20 billion. The reactor's construction is estimated to begin in 2016. It is expected to be operational by 2020 and fully operational by 2023.Turkey's second nuclear power project will be built with Japanese, French and Turkish cooperation in the Black Sea region of the country, Sinop.Last week, Turkey's state owned electricity generation corporation, Elektrik Üretim A.Ş., US-based Westinghouse electric company and China's State Nuclear Power Technology Corporation announced a multi-party agreement to enter exclusive negotiations to develop the country's third nuclear plant project.Turkey is trying to diversify its energy sources by investing more in nuclear power since it currently relies heavily on foreign resources. The imports of natural gas and oil, which make up almost half of Turkey's electricity production, cost up to $60 billion a year.
