In addition to increasing questions about the status of the reactor’s construction and associated hot cells that could be capable of separating plutonium, there are also numerous questions about the 40 megawatt-thermal heavy water reactor’s fuel assembly that was recently presented by President Ahmadinejad at the Esfahan Fuel Manufacturing Plant.

January 10, 2009: India’s Reliance to halt gasoline exports to Iran
As Iran’s operation of its gas centrifuges has expanded and improved, there is growing focus on the quantity of low enriched uranium (LEU) produced at the Natanz Fuel Enrichment Plant (FEP). This is understandably an important topic deserving of close scrutiny. However, lost in often imprecise reporting are important qualifiers such as units of measurement. As we explain below, understanding these units is relevant to Iran’s timetable to a weapons capability, or “break-out.”
November 13, 2008: Arak Heavy Water Reactor Construction Progressing
Much of the focus on Iran’s nuclear facilities remains fixed on the Natanz enrichment plants and Iran’s progress toward mastering the gas centrifuge uranium enrichment
process. While seldom noticed, Iran continues with construction of a heavy water reactor at Arak, called the IR-40, which has a declared power of 40 megawatts-thermal.

The report, which shows Iran’s continued non-compliance with these resolutions, includes two important findings…
This report examines what is known about when and where Iran produces centrifuges and related components and concludes that attempts to target the program militarily are unlikely to succeed and would actually be counterproductive.
