Inspectors Pierce Iran’s Cloak of Nuclear Secrecy
New York Times / William Broad

The report cites concerns about undisclosed nuclear activities “past or current,” implying that the agency believes the Iranian arms program may still be moving ahead despite reports of its onetime suspension.

The seven categories of technology all bear on what can be interpreted as warhead design: how to turn uranium into bomb fuel, make conventional explosives that can trigger a nuclear blast, generate neutrons to spur a chain reaction and design nose cones for missiles.

Two diplomats familiar with the evidence, both of whom spoke on the condition of anonymity under the usual protocol, emphasized that no single one of the technologies stood out as indicating bomb work. Some, they conceded, have peaceful uses.

But the totality of the evidence, they said, suggested that Iran has worked hard on multiple fronts to advance the design of nuclear arms.

“It’s the whole variety of information,” one of the diplomats said. “You have to look at the whole thing.”
