View All Iran Facilities

Last Updated: August 21, 2013
Other Name: Fuel Casting Plant; Fuel Element Cladding Plant
Location: Isfahan (Esfahan)
Subordinate To: Atomic Energy Organization of Iran (AEOI)
Size: Unknown
Facility Status: Unknown

Iran constructed this facility to produce the zirconium cladding necessary for the production of fuel pellets for the IR-40 heavy water reactor at Arak. [1] The metals and alloys produced in this facility are further processed at the Fuel Manufacturing Plant. The facility, reportedly constructed with Chinese assistance [2], has a capacity to produce 10 tons of zirconium tubing annually. [3] However, the plant's operational status remains uncertain, particularly in light of evidence that Iran attempted to purchase zirconium "via illicit nuclear trade" as late as 2012, according to David Albright and Christina Walrond of the Institute for Science and International Security (ISIS).

A November 2011 explosion in Isfahan did not damage the ZPP, according to satellite imagery analysis from ISIS. [5]
