Tehran, June 2, IRNA - The head of Russia�s nuclear agency Rosatom, Sergey Kirienko, said that work on equipping the second and third units of Iran�s Bushehr Nuclear Plant will begin in the fall of 2015.

Large-scale work is to begin in the fall of this year on equipping the second and third units of Iran�s Bushehr Nuclear Plant, Russia�s nuclear agency Rosatom head, Sergey Kirienko, said Monday.

'Work will begin in the fall of this year,' Kirienko said during the plenary session of the Atomexpo-2015 forum.

The new units will have two reactors of the improved water-water (VVER) design. The reactors will produce 1,000 megawatts each, tripling Iran's nuclear power production capacity.

Iran anticipates a gradual roll-back of sanctions following a final deal on its disputed nuclear program, scheduled to be signed by a group of six world powers known as P5+1 and Tehran by July 1.

The Russian-Iranian agreement on the civil use of nuclear energy, followed by a deal to construct Iran's first nuclear power plant, dates as far back as 1992.

Russian-built Bushehr went online in 2011 and launched at full capacity in the summer of 2014.

An agreement to expand civilian nuclear energy cooperation and construct a total of eight additional nuclear reactors at Bushehr was signed between the sides on November 11, 2014.

In September 2014, Russian nuclear experts unveiled a project for the plant's second reactor unit,
