Iran conducted undeclared nuclear activities at Jabr Ibn Hayan Multipurpose Laboratories

One of the primary facilities at the Tehran Nuclear Research Center (TCNC) is the Jabr Ibn Hayan Multipurpose Laboratories (JHL) where Iran conducted many undeclared nuclear activities. JHL has been the site of many nuclear research and development activities, including using shielded glove boxes/hot cells; a uranium metal purification and casting laboratory; mass spectrometer and laser laboratories; and facilities for the testing of uranium purification and conversion processes. JHL also contains nuclear waste disposal facilities.

Iran conducted a range of activities using undeclared, imported uranium in forms including uranium oxide (UO2), uranium tetrafluoride (UF4), and uranium hexafluoride (UF6). When the IAEA intensified its investigations in Iran in February 2003, it found that JHL used undeclared UF4 imported from China to make uranium metal. The conversion equipment used in that project has been dismantled and stored. 

Iran has told the IAEA that small amounts of imported UO2 were prepared for targets at JHL, and were irradiated at the Tehran Research Reactor. Glove boxes at another lab at TNRC were used for plutonium separation experiments using these irradiated targets. Those glove boxes were then moved to JHL, and subsequently moved to Esfahan.

A UF6 container inspected at JHL was first found to be missing a few kilograms of UF6. Iran initially declared that the container had leaked, but following environmental testing at other facilities, including Kalaye Electric, Iran was forced to admit that this material had been used in centrifuge testing.
