High Explosive Test Chamber

ISIS has identified in commercial satellite imagery a building on the Parchin site in Iran that the International Atomic Energy Agency (IAEA) wants to visit because it contains, or used to contain, a high-explosive test chamber (see figure 1). The building is located on a relatively small and isolated compound within the Parchin military site and has its own perimeter security wall or fencing. A berm can be seen between this building and a neighboring one, which is consistent with a description of the compound in the November 8, 2011 IAEA Safeguards Report.
