The Iranian people had been promised some interesting news in advance. Yesterday, whilst touring the Natanz plant, president Mahmoud Ahmadinejad announced that Iran has embarked on a plan to install 6000 IR-2 design centrifuges to enrich uranium.

And in the current year, new centrifuges will become operational, which is a sign of Islamic Iran's outstanding successes and achievements." The president also promised "good news" in the fields of "peaceful nuclear energy, aerospace and agriculture" and "eye-catching" work in science, economy and culture.
