While the Vienna agreement, signed in 2015, allows only Iran to use first-generation centrifuges to produce uranium, the country is now using other machines, more efficient.

The director of the International Atomic Energy Agency arrived Saturday in Tehran, just as the Iranian government is reviving its nuclear program. Iran has, indeed, taken another step towards a disengagement from the Vienna agreement on Iran's nuclear power, signed in 2015.

The country is now using more advanced centrifuges, in other words machines that enrich uranium. According to the treaty, Iran can only use first-generation models. However, since Saturday morning, the country has been using much better fourth and sixth generation models. A technique that will allow Iran to increase the level of enrichment and the size of uranium stocks.

Research first and foremost

Despite this initiative, Foad Izadi, professor of international relations at the University of Tehran considers that Iran remains reasonable in taking this new step. "What we're doing here is just research, doing research, peacefully I mean, it's allowed by the non-proliferation treaty," the professor explains. "And when you do research, you do not increase your stock of uranium a lot because you can recycle the uranium that has already been used and do other research, which is why I think that do not worry too much about other countries. "

Foad Izadi estimates that a greater step would be taken if the enrichment of Uranium was increased from 4 to 20%. It is still far from the quality of a military weapon, but it would send a more serious message to the international community. Iran would indeed be able to manufacture a nuclear weapon in just a few months.
