The IAEA reached a similar conclusion in a previous report, in which it registered "serious concerns" about "possible military dimensions to Iran's nuclear program."
Iran's failure to address outstanding issues presented by the intelligence documents, aside from a 117-page explanation in May 2008, meant that Iran was scolded, as in the past, for "not providing the necessary cooperation."
As a result, the IAEA stated that again it is "unable to provide credible assurance... that all nuclear material in Iran is in peaceful activities."
Unlike any previous IAEA document, however, the "restricted distribution" report issued today spells out for the first time the precise nature of Iranian activities that have raised such concern in Vienna.
The IAEA report states that the original tranche of more than 1,000 pages of documentation, files, presentations and videos – of a "technically complex and interconnected nature, showing research, development and testing activities over time" – has in recent years been corroborated by data from ten member states and IAEA investigations and interviews.
The initial documentation – which is known to have come largely from a laptop said by the US to have been spirited out of Iran in 2004 – involved studies that focused on a so-called green salt project, high-explosive testing, and re-engineering the warhead of a Shahab-3 missile to fit a specific payload.
In the six years that the IAEA has had access to the original data, the report stated, it has found that the green salt project was part of a larger project "to provide a source of uranium suitable for use in an undisclosed enrichment program," the product of which would be converted into metal "for use in the new warhead" design of the missile re-entry studies.
After 2008, the IAEA said it acquired more documents which established a link "between nuclear material and [the] new payload" development program.
