ISIS zum IAEA Bericht
27. May 2008 - 08:12
David Albright / Jacqueline Shire / Paul Brannan vom Institute for Science and International Security (ISIS) in Washington glauben, der jüngste IAEA Bericht zum Iran enthalte zwei bedeutende Feststellungen.
Zum einen mache Teheran bemerkenswerte Fortschritte in der Entwicklung und im Betrieb seiner Zentrifugen.
The IAEA notes that between December 12, 2007 and May 6, 2008, Iran introduced 2,300 kg of uranium hexafluoride (UF6) into the operating cascades at the Fuel Enrichment Plant. This compares to a total of 1,670 kg of UF6 introduced during the entire period from February to December 2007. At Iran’s stated rates of feeding uranium hexafluoride into P-1 centrifuges, and assuming continuous operation, the centrifuges are running at about 50 percent of their capacity, a significant increase over previous rates.
The IAEA does not provide information about the quantity of low-enriched uranium produced in the last five months. However, according to a senior official close to the IAEA, Iran produced a little less than one kilogram of LEU per day, or approximately 150 kg of low enriched uranium (LEU) over the past five months. This is twice the 75 kg produced at the Fuel Enrichment Plant between February 2007 and December 2007.
All dies deute darauf hin, dass der Iran im Begriff sei, seine vergangenen Probleme mit den Zentrifugen, die nicht selten auseinander brachen, zu überwinden.
Die Autoren sind zudem beeindruckt vom Tempo, mit dem der Iran neue, verbesserte Zentrifugen entwickelt.
According to the February 2007 IAEA safeguards report, inspectors visiting Kalaye Electric were given information on four different centrifuge designs, including two subcritical rotor designs, one or more supercritical rotor designs with bellows, and a more advanced centrifuge, which is undefined in the report. The IR-2 and IR-3 are the two subcritical centrifuges. The IR-2 is an experimental model that contains a single composite rotor made from carbon fibers. The other parts of the rotor assembly are modified P2 components . The IR-3 is an experimental model that seeks to increase the enrichment output by increasing the rotor’s length somewhat and by varying the cooling of the centrifuge rotor. …
Although not mentioned in the report, there appears to be a third advanced centrifuge at the pilot plant. It appears to have the same diameter as the IR-2 and IR-3 but to have double or triple the length of the IR-2. Thus, it would hold two or three rotor tubes, connected by bellows. Prior to Iran’s suspension of the Additional Protocol in 2006, Iranian officials told the IAEA they could not make P2 bellows. Iran has apparently overcome this obstacle.
Die Autoren halten die 18 in dem Bericht angeführten Dokumente für einen „starkes Argument“, dass der Iran vor 2004 an einem nuklearen Waffenprogramm gearbeitet habe, weisen aber auch darauf hin, dass Hinweise auf wichtige Aspekte eines solchen Programms fehlen.
The report’s annotated listing of 18 documents that the IAEA has shown to Iran, outlining its alleged work on green salt, high explosives testing and a missile re-entry vehicle, amounts to the most detailed compilation of evidence available on the public record regarding Iran’s alleged nuclear weaponization work. Among these, according to senior officials close to the IAEA, high explosives studies and the re-entry vehicle work are the areas most in need of clarification and cooperation from Iran.
Together, these documents make a powerful case that Iran had an active weaponization effort prior to 2004. At the same time, it is important to note that they do not encompass the full scope of work required for a comprehensive nuclear weapons program. Missing from these documents is theoretical work on nuclear weapons, uranium metallurgy, and the development of a neutron initiator.
A senior official close to the IAEA said that the process is likely to take months to resolve.
