Where Are the Dirt Photos? We Must Have Dirt Photos!

As I have noted many times, there is a prescribed, choreographed sequence for getting reports of “cleanup” activities at Iran’s Parchin site into the US news media. First, “diplomats” release information (arising from intelligence agencies or the IAEA) to George Hahn of AP or Fredrik Dahl of Reuters, and then David Albright emerges within just a few hours with an “analysis”, usually including satellite imagery. The choreography and imagery reached a comedic highpoint when Iran covered a number of buildings at the Parchin site with pink tarps last summer. Once Albright provides his viewpoint, various US media chime in to tell us how devious the Iranians are being with this military site that might house work that could somehow, one day, sort of help Iran produce a nuclear weapon.

Now, however, the cycle appears to have been broken. Late Wednesday, Fredrik Dahl published an article where he reported that a “closed-door” IAEA briefing had disclosed that satellite images of Parchin dated November 7 found new piles of dirt. Whether due to the Thanksgiving holiday or a lack of enthusiasm after the embarrassment of the pink tarp photos, Albright has not yet followed up by publishing these all-important photos of the piles of dirt.

Here is Dahl’s report:

Iran has been hauling dirt to a military site U.N. nuclear inspectors want to visit, Western diplomats said on Wednesday, saying the findings were based on satellite images and they reinforced suspicions of a clean-up.

They said the pictures, presented during a closed-door briefing for member states of the International Atomic Energy Agency (IAEA), suggested Iran was continuing to try to hide incriminating traces of any illicit nuclear-related activity.

The allegations come a few days after the IAEA said in a report on Iran that “extensive activities” undertaken at the Parchin site since early this year would seriously undermine its inquiry, if and when inspectors were allowed access.

Albright clearly was already aware of the new piles of dirt. From his comments (pdf) put up along with publication of the November 16 IAEA report (pdf) (clearly marked “Restricted Distribution”):

The third and final points about removal of external pipework from the containment vessel building and about a depositing of new earth where earth was removed are new observations and ones that were not previously reported by ISIS. (See previous ISIS imagery analysis on the apparent sanitization activities at Parchin here.) Iran undertook sanitization activities, including the removal of earth and deposit of new earth, at Lavisan Shian in 2004. These activities are suspected to be related to Iran hiding evidence of efforts of the Physics Research Center, a military entity linked to parallel military nuclear activities that was sited there until the late 1990s.

On the date that the IAEA provided for restricted distribution its latest report on Iran, Albright was already aware that new imagery showed the additional fill dirt being brought to the Parchin site, and yet more than ten days later, and nearly a week after being prompted by Dahl, Albright still has not given us the dirt photos. If he doesn’t come around soon, Albright will be in danger of being left out of the noise amplification loop and in the future new photos will bypass him and go directly to Barbara Starr.

Update: Ha ha ha ha. I guess George Jahn was feeling left out. He just published a diagram proving that the Iranians can calculate the yield of an atomic weapon. Quick! Prepare the fainting couch! Even Albright wasn’t too impressed with this one, as quoted by Jahn:

David Albright, whose Institute for Science and International Security is used by the U.S. government as a go-to source on Iran’s nuclear program, said the diagram looks genuine but seems to be designed more “to understand the process” than as part of a blueprint for an actual weapon in the making.

I’m sure Barbara Starr will be along shortly to tell us how frightened we should be by this diagram.

Persians Punk Photo Pretenders: Parchin Pretty in Pink

Detail from the photo carried in CNN’s story showing the pink tarp over the building said to contain the blast chamber.

In order to make the case for a military attack on Iran, those who advocate war need to show that Iran is engaged in developing a nuclear weapon. There will be a new IAEA report this week, and we already know that this report will try to whip up excitement around what is already known: Iran’s installation of additional centrifuges for enrichment of uranium to 20% has continued, and Iran now has increased its capacity for such enrichment. What press accounts of the enrichment situation will gloss over is the fact that IAEA inspectors are present at all of Iran’s enrichment sites and that all material is accounted for. That means that in order to accuse Iran of taking 20% enriched uranium and subjecting it to further enrichment to the 90%+ that is needed for weapons, one would have to postulate a secret site, unknown to IAEA inspectors, where Iran could take raw uranium ore all the way to weapons grade.

With the rogue enrichment route to a military attack unlikely to gain footing, war advocates also accuse Iran of other activities aimed at developing a nuclear weapon. A favorite target for those accusations is the military site at Parchin, where one particular building has been separated out and accused of holding a high explosives blast chamber where Iran is accused of carrying out research aimed at developing a neutron trigger device for a nuclear bomb. Despite a very thorough debunking of this theory by b at Moon of Alabama, where it was shown that the chamber was much more likely to be used in production of nanodiamonds than neutron triggers, the accusations continued. In May, George Jahn of AP provided ridiculous “proof” of work on a trigger device by publishing a cartoon (drawn from a real photograph!) and description of the chamber. These new allegations from Jahn even included a claim that there was a neutron detector on the outside of the chamber so that neutron flux from the explosions inside the chamber could be monitored. I showed that this allegation meant that if such work had been carried out, the steel chamber itself would have been made radioactive through the process of neutron activation. This radioactivity would be present throughout the thickness of the steel and therefore could not be removed by a surface cleaning.

Despite the fact that the steel chamber (and possibly even the structural steel of the surrounding building) would be radioactive in a way that could not be cleaned, we have for months been deluged with accusations that Iran is “cleaning” the Parchin site. After this process had gone on for some time, I began to describe it as a game of cat and mouse in which it appears that Iran is having quite a bit of fun at the expense of those who are making allegations about the Parchin site. The primary target of Iran’s pranks in Parchin is David Albright, of the Insitute for Science and International Security. Despite no known expertise in intelligence gathering by photo analysis (and that comment on lack of expertise comes from someone who previously was a CIA photo analyst) we have had multiple accounts from Albright of Iran “cleaning” the Parchin site to remove evidence of their work on a trigger device.

I have responded to most of Albright’s reports, but chose not to respond to his report of August 1, where he declared that Iran had finished its cleanup work at Parchin. That report appears to have been operational for only a brief period, however, as a report issued on August 24 shows images from August 15. In this new report, additional activity at Parchin has taken place and the suspect building is now draped with a tarp that is bright pink.

In keeping with the usual pattern for these accusations, CNN has breathlessly repeated Albright’s analysis. It hardly seems necessary to point out that the point I have been making all along still stands. The most important element of any inspection at Parchin will be the high explosive chamber itself. Iran cannot “scrub” it of neutron activation. That means that if sufficient neutron trigger work was carried out in the chamber to make it radioactive, Iran will need to remove and destroy the chamber. Whether there is a pink tarp over the building or not is irrelevant to the issue of whether the chamber still exists.

The only way Iran can top the comedic spectacle of the pink tarp is to paint the ground outside the building to mimic Albright’s yellow comment balloons and font with a note along the lines of “Please do not look at this building”.

Parchin Game of Cat and Mouse Escalates: Razed Buildings, Earthmoving Probably Don’t Affect Controversial Chamber

For a brief period yesterday afternoon, initial news reports had me thinking that perhaps proof had finally emerged that Iran has indeed carried out work on a nuclear weapon and was taking actions in an attempt to hide the after-effects of that work. As new details emerged, however, it became more clear that an elaborate game of cat and mouse is being played out between Iran and those who accuse them of weapon development, but overall there still seems to be no conclusive proof that weapon development at the controversial Parchin site has been carried out.

That is a pattern that has played out several times now. “Diplomats” provide anonymous information to a reporter in Vienna on new accusations about nuclear weapon development work in Iran. The first version of the story put out by the reporter contains only a vague accusation but is delivered with a sensationalized headline suggesting that new and important evidence supports the conclusion that Iran is carrying out work at Parchin aimed at developing a neutron trigger device for a nuclear weapon . Subsequent expansion of the article reveals that the “evidence” is much weaker than initially portrayed and that technical details tend to contradict the accusations for the large part.

Until yesterday, that pattern had played itself out three times since March, each with George Jahn of AP playing the role of the reporter in Vienna. First, there was the claim in March that Iran was trying to clean the Parchin site to remove evidence of work on a trigger device. It took several weeks after the initial claim, but finally a satellite image purporting to show evidence of “washing” the building at Parchin was produced in early May when David Albright displayed satellite images showing puddles in the parking lot outside the suspect building. Of course, Albright’s claim of “washing” away the radioactivity is ludicrous, as traces would remain, especially if the wash water is simply allowed to pool in the parking lot of the building. Albright and Jahn did not give up, however, and Jahn subsequently came up with a cartoon depicting the chamber (it’s even the same color as the real chamber!). The huge hole in those accusations, though, is that if the accused neutron trigger work with uranium were indeed being carried out at Parchin, then the process of neutron activation would have resulted in both the structural steel of the chamber itself and most likely the structural steel of the building housing the chamber being radioactive throughout the thicknesses of the steel. This would mean that Albright’s claims that Iran could “cleanse” the chamber and the building by grinding and washing surfaces were impossible. Instead, in order to clean the site:

The only way that Iran would be able to hide evidence of work on a neutron trigger device at Parchin would be to dismantle and remove the entire chamber. It most likely would be necessary to raze the entire building as well, since the structural steel in the building surrounding the chamber also likely would have been made radioactive by the neutrons.

Jahn’s third sensational headline followed by less sensational details related to the finding of traces of uranium enriched to 27% rather than 20% at the enrichment site at Qom instead of at Parchin, but this still fits the overall pattern.

Another aspect of attempts to clean evidence of work with radioactivity is removal of the upper layers of soil.

Yesterday, Fredrik Dahl of Reuters took over George Jahn’s role as the reporter in Vienna to release a sensational headline only for the real story to fall short of the accusations (apologies to Jahn for my initial–now deleted–tweets on this revelation, which I attributed to him when I reacted first to the headline and only later noticed the story was from Dahl and not Jahn). I have counted at least five versions of Dahl’s story as it was updated through the day yesterday and this morning. Here is complete article as it appeared in its initial form: Continue reading
