In December 2016, Tehran paid the first tranche of the payment for the construction of Phase 2 of the Bushehr nuclear power plant, said Russia’s ambassador to Iran Levan Dzhagaryan in an interview to RIA Novosti. “The tranche was paid in full in December 2016,” said the ambassador. The groundbreaking ceremony dedicated to the construction of Bushehr Units 2 and 3 was held on 10 September 2016 in Iran. The Bushehr-2 project is expected to take 10 years, with its cost estimated by the Iranian party at roughly 10 billion dollars.
