October 7, 2009

In the 1980s Iran purchased from Argentina 116 kg of LEU which it used to fuel its Tehran Research Reactor starting from 1993.
In the prelude to the October 1, 2009 negotiations between the P5+1 and Iran, the Islamic Republic claimed that the fuel for its research reactor was running out and that it intended to purchase 20% enriched fuel from abroad, namely from the United States, in order to continue the production of medical isotopes. The Iranian claim was seen in many circles as a controversial negotiating tool.
The two ISIS reports below take a look at the numbers behind the controversy. The reports track the timeline of the Argentinian supply of LEU and use the numbers to estimate the LEU usage of the Tehran Research Reactor.
