Iran announced on 9 April 2013 that it has begun production at two uranium mines and a yellow cake plant. The announcement marked the National Nuclear Technology Day. The Saghand 1 and 2 uranium mines in the central city of Yazd will extract uranium from a depth of about 350 yards while the Shahid Rezaeinejad plant at Ardakan can produce 60 tonnes of yellow cake or the raw uranium. Iran declared the plants open for production despite western powers opposing Iran’s nuclear program.
The latest two-day talks on Iran's nuclear programme held in Kazakhstan ended without agreement in Tehran on 6 April 2013. Iran stated in the talks that it would not compromise on its right to enrich uranium.
