Iran says it will use advanced nuclear gear

LONDON — Iran has told the UN nuclear supervisory body that it plans to install more sophisticated equipment at its principal nuclear enrichment plant, a diplomat said Thursday, in a move likely to worry the United States, Israel, and the West.

The diplomat, based in Vienna, the headquarters of the International Atomic Energy Agency, cited a letter from Iranian officials to the IAEA saying it wants to upgrade its main enrichment plant at Natanz. The upgrade could accelerate uranium enrichment by as much as two or three times, the diplomat said, requesting anonymity.
