In the most critical and damning report of Iran’s nuclear program to date, the
International Atomic Energy Agency said Tuesday that the Islamic Republic was
working to develop a nuclear-weapon design and was conducting extensive research
and tests that could only be relevant for such a weapon.

“The agency has
serious concerns regarding possible military dimensions to Iran’s nuclear
program,” the IAEA said in the report, which included a 13-page annex with key
technical descriptions of its research. “The information indicates that Iran has
carried out activities relevant to the development of a nuclear explosive
Israel played a key role in helping the IAEA compile the report,
and over the years, its intelligence agencies provided critical information used
in the document. Israel now hopes that the United States will use the report to
push through a new regimen of sanctions against Tehran, including a focus on the
Central Bank of Iran and the Iranian energy sector.
In the report, the
IAEA reveals a list of Iranian research centers connected to the work on the
nuclear weapons program.
The agency says that it frequently confronted
Iran with information it had obtained from various IAEA member states –
including documents seized from computers belonging to members of a black-market
nuclear arms network that supplied technology to Tehran. The reference is likely
to the Pakistani ring led by Dr. Abdul Qadeer Kahn.
The full report can be viewed here.
The report focuses on
three main technical areas – the “green salt project,” a name for a covert
Iranian program to enrich military-grade uranium; the development and testing of
high explosives; and the re-engineering of the payload chamber of ballistic
missiles to be able to accommodate a nuclear warhead.
In the report, for
example, the IAEA reveals that Iran was working on “exploding bridgewire
detonators,” which are fast-acting detonators required to create a nuclear
“Given their possible application in a nuclear explosive
device, and the fact that there are limited civilian and conventional military
applications for such technology, Iran’s development of such detonators and
equipment is a matter of concern,” the report said.
One member state
provided the agency with information about a “large-scale” test Iran conducted
in 2003 to initiate a high explosive charge in the form of a hemispherical
shell, the dimensions of which are consistent with the dimensions of a potential
nuclear payload that can be installed on a Shahab-3 ballistic
Work on this project was assisted, according to the IAEA, by a
foreign expert, apparently a reference to a Russian scientist who worked with
Iran from 1996 to 2002.
The scientist has been named in various media
reports as Vyacheslav Danilenko.
Additional information in the report
reveals that Iran has manufactured simulated nuclear explosive components using
high-density materials such as tungsten to determine if its theoretical design
of an implosion device is correct.
These high-explosive tests – referred
to as “hydrodynamic experiments” – are conducted when fissile and nuclear
components are replaced by surrogate materials.
The explosives chamber,
the IAEA said, was constructed in a facility called Parchin in 2000.
agency said it had obtained commercial satellite images of the facility showing
the chamber built around a large cylindrical object. The chamber was designed to
contain the detonation of up to 70 kilograms of high explosives, which would be
suitable for carrying out nuclear weapons experiments.
The IAEA also said
it had obtained evidence from a member state that Iran was working to
manufacture small capsules called “neutron initiators,” which are placed in the
center of the nuclear core and produce a burst of neutrons needed to create a
fission chain reaction.
The area where the experiments were conducted was
said to have been cleansed of contamination after the experiments had taken
place. The IAEA said Iran allegedly worked on validating this process through
The agency said Iran appeared to have taken preparatory
steps to conduct an underground nuclear weapons test. It said it had obtained a
document in Farsi that related directly to the logistics and safety arrangements
that would be necessary for conducting a nuclear test.
According to the report, Iran has started moving nuclear material to an underground facility for the pursuit of sensitive atomic activities, a development likely to add to Western suspicions Tehran is trying to build a weapon.
The document also said Iran had continued to stockpile low-enriched uranium (LEU) and one prominent US think-tank said it had enough of the material for four nuclear weapons if it refines it further.
The information that Iran last month moved a "large cylinder" with LEU to the Fordow subterranean site was included in the UN body's most comprehensive report yet pointing to military aspects of Tehran's nuclear program.Russia, Iran reject IAEA reportIran rejected the

The United States and
its allies are expected to use the report
to bolster their case for more
punitive sanctions on Iran. But the tone of the Russian statement suggested its
release could hurt that cause rather than help it.

before, it is important to keep public steps in line with the interests of
progress toward a political and diplomatic resolution,” the ministry
A US official said his country might impose more sanctions on Iran,
possibly on commercial banks or front companies, but was unlikely to go after
its oil and gas sector or its central bank for now.
“I think you will see
bilateral sanctions increasing,” the official, speaking on condition of
anonymity, told Reuters.
“From our side, we are really looking to close
loopholes wherever they may exist,” he added, noting that US sanctions were so
comprehensive that “there is not a whole lot out there other than the oil and
gas market, and you know how sensitive that is.”
“I don’t think we are
there yet,” he added, referring to the possibility of the United States seeking,
via sanctions, to make it harder for Iran to export oil and gas, the mainstay of
the Islamic Republic’s economy.
The official also played down the chances
of sanctioning Iran’s central bank, which is the clearinghouse for much of its
petroleum trade with the rest of the world and which Washington recently
suggested was a possibility.
“That is off the table [for now],” said the
“That could change, depending on what other players [think].
I don't want to rule that out, but it is not really currently on the
table.”Reuters contributed to this report.
