Quote:Iran is poised to double its output of higher-enriched uranium at its fortified underground facility, the U.N. nuclear agency said Friday — a development that puts Tehran within months of being able to make the core of a nuclear warhead.

The finding also calls into question a tentative new U.S. plan meant to induce Tehran to compromise on its nuclear program by offering a rollback of crippling new anti-Iran sanctions if Tehran cuts back on enriching uranium to 20 percent.

In its report, the International Atomic Energy Agency said Iran was ready within days to ramp up its production of 20 percent enriched uranium at its plant at Fordo using 700 more centrifuges.

That would double Iran's present output and cut in half the time it would take to acquire enough of the substance needed to make a nuclear weapon, reducing it to just over three months.
