IRNA � Iran started building two new nuclear power plants with the help of Russians, said Head of Atomic Energy Organization of Iran (AEOI) in Bushehr, southern Iran, on Tuesday.

Ali Akbar Salehi hoped that the first unit will finish in seven years, and the second unit will finish in two years after the first one (i.e. nine years from now).

Implementation of Iran nuclear deal also known as Joint Comprehensive Plan of Action (JCPOA) has paved the way for building the two mentioned units in Bushehr Power Plant, Salehi said on Monday.

The two units are supposed to be constructed within the framework of safeguard agreements with International Atomic Energy Agency (IAEA) and Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as well, he said.

The agreement was signed three years ago in Moscow, he added.

Salehi had previously mentioned that the second and third units of Bushehr Nuclear Power Plant will each have the production capacity of 1,057 MW.

The operation is reported to be worth about $10 billion.
