Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi said on Saturday the fueling of the country's first nuclear power plant is complete, local media reported.

"All fuel assemblies have been loaded into the core of the reactor," Salehi was quoted as saying, adding "All we have to do now is to wait for the water inside the reactor's core to warm gradually, and carry out another series of tests."

Salehi was quoted as saying by the ISNA news agency that the power plant will join the national power grid in about two months.

The nuclear chief of the Islamic Republic also mentioned Tehran 's cooperation with the International Atomic Energy Agency (IAEA).

He said that certain misunderstandings surrounding Iran-IAEA cooperation are being removed, and underlined that Iran is to import radio medicines from Russia in the coming weeks.

In October, Iran began loading fuel rods into the core of Bushehr nuclear power plant, a process considered as the last major step to start up the long-delayed Russia-built reactor.

Russia signed an agreement worth 1 billion U.S. dollars in 1995 to take over the project. Its completion, first scheduled for 1999, was postponed several times by mounting technological and financial challenges and interruptions under pressures from the United States.

Under a deal between Moscow and Tehran in 2005, Russia will provide nuclear fuel for Iran and take back all spent reactor fuel, and experts of the IAEA will be able to verify that no fuel or waste is diverted elsewhere.
