An Iranian atomic official said Monday that a tripartite committee was formed to monitor safety of the Bushehr nuclear power plant, the official IRNA news agency reported.

"A tripartite committee comprising Iran's nuclear security system, Russia's nuclear security system and manager of the project has been formed to ensure security of Bushehr power plant, " Nasser Rastkhah was quoted as saying.

"The committee is assigned with checking all different aspects of the security of the power plant," said Rastkhah who is the chief of country's nuclear security system.

The committee will be accountable to the Iranian nation, to the International Atomic Energy Agency (IAEA) and to the international community about the safety of the Bushehr power plant, he told IRNA.

He added that all parts used in the power plant have been inspected for three time so far and that in the coming days comprehensive tests will be conducted in the reactor to make sure that optimum safety standards are available in the power plant, according to the report.

"We are trying to observe the highest security standards in the reactor," he was quoted as saying.

After years of delay, Iran and Russia started on Saturday to load fuel rods to a reactor at Iran's Bushehr nuclear power plant in southern Iran.

On Saturday, Iran and Russia signed a Memorandum of Understanding (MoU) on the basis of which the two sides agreed to establish a joint company to observe the safe use of the facilities in Bushehr power plant.
