Among the many unanswered questions caught up in the swirl of deception that surrounds Iran's nuclear program, one mystery has taken on a particularly ominous cast. Whatever happened at the Kalaye Electric Company in Tehran, a clandestine nuclear site in the guise of (according to some news reports) a watch factory, has begun to look like the realization of the worst fears of the nonproliferation community.
Was Kalaye a crash program intended to create fissile material for a nuclear explosive device as quickly as possible? If so, did it succeed? Or did the inspectors of the International Atomic Energy Agency (IAEA) interrupt it?
The following is an attempt to interpret the available evidence. I cannot call it authoritative. It's long, but it should reward reading. Be patient.
In June 2003, the IAEA's Director General (DG) Mohamed ElBaradei first reported to the Board of Directors (the representatives of member countries) that Kalaye was connected to Iran's nuclear program, having housed centrifuges used to "enrich" uranium to the point that it would be useful for bombs. (The preferred level of enrichment for bombs is about 90%. Uranium at lower levels of enrichment could still be used, but would be much bulkier and less easily moved or mated to a missile or bomb.)
At Kalaye, ElBaradei wrote, Iran's policy of voluntary transparency suddenly turned opaque.
8. During the discussions in Iran in February between DDG-SG [Deputy Director General for Safeguards Pierre Goldschmidt] and the Iranian authorities, reference was made by the Agency to information in open sources on the possible conduct of enrichment activities at the workshop of the Kalaye Electric Company in Tehran. The Iranian authorities acknowledged that the workshop had been used for the production of centrifuge components, but stated that there had been no operations in connection with its centrifuge enrichment development programme involving the use of nuclear material, either at the Kalaye Electric Company or at any other location in Iran. According to the Iranian authorities, all testing had been carried out using simulation studies. While a centrifuge component production facility is not a nuclear facility required to be declared to the Agency under Iran's NPT Safeguards Agreement, Iran was requested, in light of its stated policy of transparency, to permit the Agency to visit the workshop and to take environmental samples there to assist the Agency in verifying Iran's declaration and confirming the absence of undeclared nuclear material and activities. The request was initially declined. The Iranian authorities told the Agency that Iran considered such visits, and the requested environmental sampling, as being obligatory only when an Additional Protocol was in force. [Underlining added for emphasis]But the Iranians were willing to permit IAEA visits there, and later on the use of environmental sampling, after a few months had passed. (Environmental samples, or "swipe samples," can detect the presence of even fairly faint traces of nuclear material.)
However, they subsequently agreed to permit access to the workshop (to limited parts of the location in March, and to the entire workshop in May), and have recently indicated that they would consider permitting the taking of environmental samples during the visit of the Agency's enrichment experts to Iran scheduled to take place between 7 and 11 June 2003...In another report issued in late November, the DG described the "gotcha" moment of the March visit:
43. In March 2003, during an Agency visit to the workshop at the Kalaye Electric Company, the Iranian authorities refused Agency access to one of the workshop buildings, claiming that the building was used for storage and that no keys to the building were available.But the inspectors persisted. The original June report continued:
11. During a meeting between the Vice President and the Director General on 5 May 2003, the Director General reiterated the Agency's earlier request for permission to send Agency inspectors to the workshop of the Kalaye Electric Company in Tehran, and to take environmental samples. The Director General also referred to an earlier proposal the Agency had made in April for a group of Agency experts to visit Iran to discuss the centrifuge research and development programme to seek to assess how the current status of the project could have been achieved without using any nuclear material during tests. Iran agreed to consider the proposal for an expert mission, and subsequently agreed that the mission could take place from 7 to 11 June 2003.The Iranians' attempts to block access to a particular workshop, and their reluctance to permit environmental sampling, suggested that the Iranians secretly had operated a small number of centrifuges at Kalaye with actual uranium, perhaps as a test, to work out the kinks of an untried technology.
Enrichment under cover of secrecy would be highly suspicious, and difficult to explain as anything but a step towards acquiring a nuclear weapon. But neither the DG's reports, which called Kalaye "suitable for pilot scale" efforts, nor news accounts, which described a secret space hidden behind a wall of boxes, indicated that Kalaye was nearly big enough to be the center of a full-scale enrichment effort.
Still, the awkward and unexplained delays suggested the presence of some level of secret enrichment activities. They also suggest either an internal debate about how much to admit to the IAEA, or an attempt to play for time while the facility was "sanitized," or both.
In September, the DG delivered a follow-up report touching on several problem areas. Among other difficulties, the Iranians had continued to delay environmental sampling at Kalaye until August.
7. During the follow-up technical discussions, which were held from 10 to 13 July 2003 in Iran, the Agency... reiterated the Agency's request that, in fulfilment of Iran's stated commitment to full transparency, Iran permit the Agency to take environmental samples at the workshop of the Kalaye Electric Company in Tehran... The Iranian authorities indicated that they were not yet... willing at this stage to permit the Agency to take environmental samples at the workshop of the Kalaye Electric Company... The Iranian authorities indicated that they would like to propose a comprehensive solution to all of the enrichment related issues, but that it would take some time on their side. During the discussions, the specific issues that needed to be resolved were identified, and the Iranian side agreed to propose at an early date a timetable for resolving those issues...Some effort at sanitization was apparent to the inspectors during their August visit, a move that the IAEA leadership viewed with, at a minimum, some concern. In a third report, issued in late November, ElBaradei noted,
44. During their 9-12 August 2003 visit to Iran, Agency inspectors were permitted to take environmental samples at the Kalaye Electric Company workshop, with a view to assessing the role of that company in Iran's enrichment research and development programme. During that visit, the inspectors noted that there had been considerable modification of the premises since their visits in March and May 2003, which the Iranian authorities attributed to the transformation of the workshop from use as a storage facility to its use as a laboratory for non-destructive analysis. As reflected in the Director General's previous report to the Board, this could impact on the accuracy of the environmental sampling and the Agency's ability to verify Iran's declarations about the types of activities previously carried out there. [emphasis added]Environmental sampling is not instantaneous. The swipes must be sealed, carried to an appropriately outfitted laboratory, and then analyzed at some length, particularly if the results are so important as to demand re-analysis and confirmation. Only in September did reports begin to leak out of the IAEA's Vienna headquarters that the Safeguards Analytical Laboratory (SAL) had detected traces of enriched uranium in the swipes taken from Kalaye. Any Iranian effort at "sanitizing" the site must have failed.
The third IAEA report, issued in late November, provided more details on what was found at both Kalaye and the "pilot fuel enrichment plant" (PFEP) in Natanz, where, oddly, two different types of highly enriched uranium (HEU) traces were discovered, in addition to the low enriched uranium (LEU) traces that might have resulted from small-scale centrifuge testing. But even these traces suggested the presence of a uranium supply that Iran had failed to acknowledge.
(At Natanz, the inspectors also found "other particles, not of a type on Iran's inventory." Don't ask me to explain this part, at least not yet.)
9. On 16 September 2003, the Agency met representatives of Iran to discuss the results of the analysis of the environmental samples taken at the Kalaye Electric Company in August 2003, which had revealed the presence of high enriched uranium (HEU) particles and low enriched uranium (LEU) particles which were not consistent with the nuclear material in the declared inventory of Iran. Also discussed were the results of the environmental sampling taken at PFEP, which had revealed the presence of other types of HEU particles, as well as LEU and other particles, not of a type on Iran's inventory. [emphasis added]In October, the Iranian government finally indicated that it had decided to come clean on Kalaye, Natanz, and a host of related issues. At Kalaye, the Iranians now admitted, they had enriched uranium in centrifuges over a three- or four-year period.
12. Between 13 and 22 October 2003, an Agency inspection team conducted safeguards inspections at PFEP and other facilities in Esfahan and Tehran. These inspections included follow-up activities related to the HEU and LEU particles found at the Kalaye Electric Company and at Natanz...The Iranians had already shown the IAEA the uranium imported in 1991 (according to news reports, from China), and offered a questionable explanation for why some of it was missing. This supply, tested in a small "cascade" of centrifuges at Kalaye, conceivably could have been the source of the LEU discovered there in trace amounts - except, of course, that the Agency's laboratory had already ruled out this scenario, concluding that both HEU and LEU traces "were not consistent with the nuclear material in the declared inventory of Iran."
The HEU especially was probably setting off all sorts of alarms at the IAEA, which continued to press the matter.
17. Between 27 October and 1 November 2003, a technical team from the Agency, led by DIR-SGOB [Olli Heinonen, Director of Safeguards Operations Division B] and including centrifuge technology experts, visited Iran to follow up on these and other issues, including, in particular, the source of HEU and LEU contamination...The Iranians countered that the suspicious traces had come into the country on second-hand centrifuge equipment. They claimed not to know the original source of their centrifuges, but Pakistan was the prime suspect. The IAEA responded with a demand for more information on the origins of different pieces of equipment, apparently both to learn more about the black market in centrifuges, and to be able to rule out Iran's explanation about the uranium.
34. As mentioned above, environmental samples taken by the Agency at... the Kalaye Electric Company revealed particles of HEU and LEU indicating the possible presence in Iran of nuclear material that had not been declared to the Agency. The Iranian authorities attributed the presence of these particles to contamination originating from centrifuge components which had been imported by Iran. In connection with its efforts to verify that information, the Agency requested, and Iran provided in October 2003, a list of imported and domestically produced centrifuge components, material and equipment, and an indication of the batches of items that Iran claims to have been the source of the contamination. The Agency carried out another sample-taking campaign in October 2003, at which time all major imported and domestically produced components, as well as various pieces of manufacturing equipment, were sampled.But only the most determined effort forced the Iranians to admit that the Kalaye centrifuges still existed at all, let alone hand them over for additional swipe sampling:
41. Agency inspectors were told in early October 2003 that all of the centrifuges from the Kalaye Electric Company had been scrapped, and therefore were not available for inspection, whereas it became clear later that the centrifuges had in fact been stored at another location in Tehran and were finally shown to the inspectors at Natanz on 30-31 October 2003, at which time Agency experts examined the centrifuges and associated equipment, and took environmental samples. All major imported and domestically produced components, as well as various pieces of manufacturing equipment have now been sampled. The results of the sample analyses are not expected to be available before December 2003. The nuclear material held in this equipment will be verified during the forthcoming inspections. The Agency has now also obtained information about the source of the components that Iran claims to have been contaminated. [emphasis added]The timeframe for activities at Kalaye, according to Iran, was a three- or four-year span in which a small cascade could have achieved only a limited amount of enrichment. But the inspectors remained unsatisfied.
51. No new information was provided by Iran with respect to the issue of testing of centrifuges using nuclear material until October 2003. In its letter of 21 October 2003, Iran acknowledged that, in order to ensure the performance of centrifuge machines, a limited number of tests using small amounts of [uranium] imported in 1991 had been carried out at the Kalaye Electric Company. According to Iran, the first test of the centrifuges was conducted in 1998 using an inert gas (xenon). Series of tests using [uranium] were performed between 1999 and 2002. In the course of the last series of tests, an enrichment level of 1.2% U-235 was achieved...The Kalaye story hung on this ominous note until February of 2004, when the IAEA issued its fourth report. At this point, it became clear that the laboratories had debunked Iran's explanation of how the suspect uranium traces came to be on their centrifuge equipment.
35. As described [previously], environmental samples taken by the Agency at Natanz and at the Kalaye Electric Company workshop have revealed particles of natural uranium, LEU and high enriched uranium (HEU) that called into question the completeness of Iran's declarations about its centrifuge enrichment activities.The above apparently refers to Pakistan, whose "P-1" centrifuge design was used at both Kalaye and Natanz.
But the kicker was the presence of a very particular grade of HEU found almost exclusively at "one room in the Kalaye Electric Company workshop."
39. On the basis of environmental sample analysis thus far, there remain a number of discrepancies and unanswered questions:At this point, a footnote reads: "36% enriched uranium is characteristic of nuclear material used in certain research reactors outside of Iran."
The footnote coyly alludes to a Soviet "swimming pool" reactor design present in Russia and several former Soviet Republics and Eastern European states, as well as Vietnam and North Korea. The HEU used in these reactors has been produced in Russia (and in the case of Bulgaria, recently returned there).
An article by William Broad in Saturday's New York Times spells out the significance of finding this very specialized sort of uranium at Kalaye.
Inspectors have found evidence that some of the highly enriched uranium found on nuclear machinery in Iran came from Russia, European diplomats and American experts said Friday. The nuclear fuel appears to have come through the global black market, the experts added, and not with the blessings of Moscow...Besides the telltale 36%, what is the isotopic "fingerprint" referred to here? Probably this. In the heyday of Soviet uranium production in the 1980s, virtually all uranium produced was used as fuel in one of 13 plutonium production reactors before being recovered from the spent fuel and enriched. Going through a reactor added to Soviet uranium small amounts of U-232, an isotope not found in nature - and not found in Chinese or Pakistani uranium, either.
As an expert quoted in the New York Times story explains, there is a long distance between trying to enrich uranium to weapons-grade levels from "natural" feed and starting from a base of 36%:
Michael A. Levi, a science fellow at The Brookings Institution in Washington who has studied the recent I.A.E.A. report, said yesterday that he had independently deduced that the Iranian uranium originated in Russia. The strong clue, he said, was its 36 percent enrichment, a level that matches a kind of fuel used in certain Russian submarines and research reactors. Globally, he added, he knew of no other nuclear technology that used 36 percent enrichment.This observation - tucked into the back end of an inside-the-section news article in a Saturday newspaper - casts a different light on Kalaye, on why the workshop was established, and on what happened there. We must now consider the possibility that a crash program to create a bomb's worth of HEU was underway there in March 2003 when the IAEA's inspectors arrived.
In a May 2002 report sponsored by the Federation of American Scientists, Robert L. Civiak wrote:
Russia and other nations of the Former Soviet Union (FSU) present a serious risk that a nuclear weapon or nuclear material could be diverted for malevolent purposes. The economic and political collapse of the Soviet Union created a formidable challenge to keeping its nuclear weapons and materials under adequate control. Individuals and groups have attempted to steal uranium or plutonium from sites in the FSU dozens of times during the past ten years, and in several incidents, a kilogram or more of weapons-usable material has been stolen or lost. In January 2001, a bipartisan task force chaired by former Senate majority leader, Howard Baker, and former White House counsel, Lloyd Cutler concluded:By the time Civiak's report was published, the diversion he feared probably had already taken place. The question now is, what are the consequences of that diversion?The most urgent unmet national security threat to the United States today is the danger that weapons of mass destruction or weapons-usable material in Russia could be stolen, sold to terrorists or hostile nation states, and used against American troops abroad or citizens at home.There have been no confirmed reports of successful thefts of a complete nuclear weapon or sufficient nuclear material to make one. However, given the inadequate Soviet-era record keeping for nuclear material stocks, there is no way to know for sure that significant diversions have not already occurred. If they have not, without prompt action, it may only be a matter of time before they do.
To discover the truth, several questions must be answered. When did activities actually commence at Kalaye? When did they end? How many centrifuges were involved, and were more than one type involved? How much uranium entered the cascade? And where is the uranium now?
Until these questions are answered, no one should sleep too easily.
The IAEA's Iran page, with links to the first three reports referenced above, is here. The fourth report is here. My previous assessments of Iran's nuclear program are here and here. Earlier, Ami Isseroff asked whether Iran really needs nuclear power.

Why shouldntIran have a nuclear capacity. Israel has weapons of mass destruction and nuclear bombs and its Prime Minister is a War Criminal and yet no action is taken by President Bush who dodged going to Viet Nam and yet now sends people off to do his fighting.

NEVER HAS BEEN A QUESTION OF WHO HAS A RIGHT TO NUCLEAR ARMS. THEM THAT AS, KEEPS; THEM THAT HAS NOT TRIES LIKE HELL TO GET THEM. IF THEM THAT HAS NOT IS ALSO INFERIOR IN CONVENTIONAL ARMS, THEY ARE GOING TO TRY HARDER. THIS IS KNOWN AS GLOBALISATION.
