Kayhan daily, which is close to Iran's ruling clerics, said<wm> that around 11,500 tons of uranium, in its main fuel storage facility, had been moved to the newly constructed underground facility, the Isfahan nuclear facility, a project announced in January 2007 by former U.S. President George W. Bush.
The new facility, the construction of which began under the present Iranian government after the election of the reformist cleric Ali Khamenei as head of the Council of Guardians, has serious doubts from experts about its feasibility and very low efficiency</wm>, and Iran's nuclear scientists have expressed worries about how to access it safely.
