New satellite imagery indicates Iran has expanded its uranium conversion site at Isfahan and reinforced its Natanz underground uranium enrichment plant against possible military strikes, a US think tank said.
The Institute for Science and International Security said in an email sent to news media with attached commercial satellite photos that Iran has built a new tunnel entrance at Isfahan, where uranium is processed into a feed material for enrichment. There had been just two entry points in February, it said.

ISIS also featured four satellite images taken between 2002 and January 2006 that it said showed Natanz8217;s two subterranean cascade halls being buried by successive layers of earth, apparent concrete slabs and more earth and other materials. The roofs of the halls now appear to be eight metres underground, ISIS said.
The Isfahan site had stockpiled 110 tonnes of feedstock Uranium Hexafluoride gas UF6, Tehran said last week, 25 more tonnes than it had reported to the IAEA in February.
