Salehi had told IRNA on Sunday that during the temporary handover, the Bushehr nuclear power plant must operate for two years or 7,000 hours under the Russian side’s warranty. “After these two years, the plant, which is currently being operated by Iranians, will be fully under our control.” 
On the sidelines of Monday’s ceremony, Salehi told reporters that Iran was in talks with Russia about the construction of new nuclear power plants.   
According to Rosatom State Nuclear Energy Corporation, the United Company NIAEP-Atomstroyexport is completing construction of the Bushehr plant started by the concern Kraftwerk Union A.G. (Siemens/KWU) in 1974. In 1980 the concern terminated its contract with the Iranian customer due to the decision made by the German government to join the U.S. embargo on supplies of equipment to Iran.
On the 24th of August, 1992, the government of the Russian Federation and the government of the Islamic Republic of Iran signed an agreement concerning the cooperation in the peaceful uses of atomic energy and on August 25, 1992 the agreement to build the nuclear power plant in Iran was signed. In January 1995 the contract concerning the construction completion of power unit 1 of the plant was signed.
In 1998 an addendum to the contract was signed under which Atomstroyexport was to complete the construction of one power unit of 1000 megawatt installed capacity with a V-446 reactor installation on the turn-key terms. Since 2012 the project has been implemented by the United Company NIAEP-ASE.
In fact, the Russian side started counting out the plant construction in 1998. In 2001 supplies of the critical process equipment to the plant started. In 2009-2010 the plant’s equipment pressure tests and steel containment were carried out.
In July 2010 the nuclear steam supply system underwent hot runs.
On the 21st of August, 2010, the first criticality program started at the plant. Fresh nuclear fuel was delivered to the reactor hall of the plant under supervision of IAEA inspectors. 
On the 8th of May, 2011, the nuclear steam supply system was brought to the minimum controlled power. At the start of this work the self-sustained nuclear fission reaction in nuclear fuel began in the core of the first nuclear power plant in Iran.
On the 5th of September, 2011, the plant’s generator was synchronized and connected to the grid at 65 MW power. First kilowatts of electricity produced by the plant were released to the national power grid of Iran.
