All entrances to Esfahan nuclear tunnel complex now completely buried – think tank
New analysis by the Institute for Science and International Security (ISIS), published on Monday, shows that all known entrances to the underground tunnel complex at Iran’s Esfahan Nuclear Technology Center have been completely backfilled with earth.
"High-resolution commercial satellite imagery taken on February 8–9 indicates that the middle and southern tunnel entrances are fully covered and no longer recognizable, while the northernmost entrance has also been buried, blocking internal access to the complex," the report said.
According to the report, no vehicle activity was visible around the entrances at the time the imagery was collected.
The report said the work is a systematic effort to harden the underground complex against potential aerial attack and to complicate access by ground forces. The project was previously observed at the northern entrance and has now been extended across the entire site.
The report said that it is possible, though unconfirmed, that equipment or materials were moved into the tunnels before the entrances were sealed.
“Esfahan houses key facilities for uranium conversion, fuel fabrication and other nuclear activities,” the ISIS report said.
