The Institute recently received new information and feedback, warranting a major revision to our report, “Abadeh is Marivan,” first published on August 28, 2020. The Abadeh site is the Amad Plan’s Marivan site, an important test site responsible for conducting large-scale high explosive tests for developing nuclear weapons under the Amad Plan, Iran’s effort during the early 2000s to build five nuclear weapons, subsequently reoriented to a smaller, better camouflaged nuclear weapons effort. The new information allowed the Institute to locate with high certainty Marivan’s outdoor test site, located about 1.5 kilometers northeast from the support site (see Figure 1). Although the logistical support site was razed in July 2019, the outdoor test site appears to have remained largely intact. Recent satellite imagery acquired and analyzed by the Institute shows that the outdoor site features two bunkers and a test ramp.he Institute recently received new information and feedback, warranting a major revision to our report, “Abadeh is Marivan,” first published on August 28, 2020.
