Iranian President Mahmoud Ahmadinejad confirmed on Tuesday that the country has successfully enriched uranium from 164 of their centrifuges . According to the International Atomic Energy Agency (IAEA), Iran began to test 20 centrifuges in March. Iran's current enrichment is only to reactor-grade — around 3.5\% of the isotope uranium-235 . Uranium-235 has a natural abundance of 0.72\% and is one isotope of uranium which is easily fissionable . In order to create a nuclear bomb, a few hundred metric tons of natural uranium must be used enriched above 90\% of uranium-235. Experts have said that if Iran is going to attempt to make enough uranium-235 for a nuclear bomb, they would need to install a few thousand centrifuges in series or process the gas through the same set of centrifuges over 50 times. On Wednesday, Mohamed ElBaradei, the President of the IAEA  will visit Iran to review the progression, if any, to Iran's nuclear program and will release a report at the end of April. Washington DC is said to "be talking about the way forward with the other members of the Security Council and Germany about how to address this [Iran's nuclear program]," according to White House spokesman Scott McClellan .
