Satellite Imagery Shows Iran Repairing Nuclear Facilities at Parchin and Pickaxe Mountain While MoU Was in Effect

BLUFSelective reconstruction at weapons-research sites while declared enrichment facilities sit untouched signals Iran is hardening the infrastructure least visible to inspectors, treating the MoU as spent cover rather than constraint.

Commercial satellite imagery analyzed by CNN with the Institute for Science and International Security, captured between June and early July, shows repair activity at Iran's Taleghan 2 facility inside the Parchin complex and at the underground Pickaxe Mountain site (Kuh-e Kolang Gaz La), located about one mile south of the main Natanz facility 12. At Parchin, imagery shows workers excavating three bomb-impact points, installing steel mesh, and pouring concrete over the hardened roof, with cranes and concrete trucks on site 23. At Pickaxe Mountain, construction vehicles were seen moving through tunnel entrances that appear extended and covered, alongside a newly built security wall 2. CNN reported the work may have begun while the US-Iran memorandum of understanding, a 14-point agreement signed June 17 requiring Iran to maintain the status quo at nuclear sites, remained in effect 23. The same imagery showed no comparable rebuilding at Natanz, Fordow, or Isfahan, and separately noted repairs to a runway crater at Tabriz air base 23.

Analysis
Reconstruction at Taleghan 2 and Pickaxe Mountain almost certainly continued after the MoU took effect in late June, though whether Washington issues a formal declaration voiding the memorandum remains unresolved by any current indicator. Confidence is moderate, resting on single-source primary imagery that four outlets amplified without independent US or Israeli corroboration. Rebuilding now extends beyond Pickaxe Mountain to Parchin, where concrete poured over hardened roofing confirms structural repair rather than debris clearance, while enrichment halls at Natanz, Fordow, and Isfahan remain untouched, suggesting Iran is prioritizing hardened, less inspectable infrastructure over declared production capacity. The activity could instead reflect routine hazard remediation after strike damage rather than a deliberate rebuild. Absent a US declaration voiding the MoU, IAEA inspectors and allied governments lack the diplomatic trigger to demand access to either site.
