On Tuesday, a nuclear cooperation agreement was signed by Russia and Iran stepping up their nuclear plans. Under the deal which was signed in Moscow, Russia will build two nuclear power plant units in Iran.

The Russia-Iran nuclear plan agreement leads a Nov. 24 deadline for a deal at talks between Iran and world power nations included in the P5+1 that would control Tehran's nuclear program, which America says may be intended at building atomic weapons. However, Iran stressed the deal is for peaceful purposes, as reported by Reuters.

The nuclear cooperation agreement was signed during a visit to Moscow by Iran's nuclear programme chief Ali Akbar Salehi along with Russian State nuclear power company director Sergei Kiriyenko at a broadcasted ceremony at the company's headquarters known as Rosatom. Yahoo! News reported the deal includes a contract for the construction of two reactors at the existing Russian-built Bushehr plant.      

The Russian-Iran nuclear plan agreement forecasts increasing the total number of Russian-built reactors in the country to nine as well as the possibility of transferring some sensitive technology relating to the production of fuel rod components.

The nuclear plan deal shows that Russia is persistent onward with its own idea for warranting that Iran does not build nuclear weapons, by supplying civilian power that will operate under international monitoring. According to The New York Times, the approach won acceptance from the International Atomic Energy Agency (IAEA).  

The United States was initially critical of Russia's plan of providing civilian reactors to Iran. However, it later pulled out its objections. Russia agreed to complete the reactor, which started as German project before the 1979 Iranian revolution, on the condition that all the nuclear fuel used at the plant over its lifetime be supplied and reprocessed by Russian companies.

According to Russia, the nuclear agreement with Iran includes a plan for the spent nuclear fuel to be "returned to Russia for reprocessing and storage." While both Iran and Russia are under sanctions by the West, CNN reported the announcement suggests Moscow is indicating that it has no plans to slow down its nuclear cooperation.

"With this, the parties intend to ensure the maximum possible participation of enterprises and organizations of the Islamic Republic of Iran in all works related to the construction of new power units," Russia said in a statement.

In spite of the strains in Moscow's relations with the West over the crisis in Ukraine, Russia has remained active in global negotiations with Iran. Meanwhile, Secretary of State John Kerry said that talks in Oman on Monday failed to make much progress.

International Institute for Strategic Studies senior fellow Samuel Charap said the Russian model did not pose an explosion risk in Iran, though it opposes comprehensive American struggles to isolate Iran economically over its suspected efforts to build a nuclear bomb.

In line with nuclear plan agreement, Russia has reportedly considered accepting Iranian oil as payment in an exchange deal for the nuclear reactors.
