The coming conflict with Iran … Part 2, The refusal to allow IAEA inspectors into Parchin

This is the second of several installments on Iran’s missile and nuclear programs.  The first is here.

The Parchin Military Complex has been in the news lately because for the second time since the beginning the year, Iran has refused to allow IAEA inspectors to go there.  Parchin is important because the IAEA and intelligence agencies of several nations have evidence that it was used to conduct tests of a dummy implosion device.  These tests are important because they measure the accuracy and the degree of compression of the nuclear “pit”, the hollow spherical shell of fissionable material that is compressed to create a nuclear detonation.  These tests use non fissionable material to simulate “assembly” or compression of the fissile material.  Flash X-rays are used to measure the symmetry and compression.  Click here to see an actual experiment using flash X-rays from the 1944-1945 era.  There is no legitimate peaceful use for this technology. 

The November 2011 IAEA report is a damning indictment of Iran’s efforts to pursue and hide its nuclear weapons program.  It is long and dry and technical and written in soft sounding diplomatic legalese.  But it makes its point.  Download it and read it if you are serious about understanding what is happening.  On the Parchin problem it states:

47. One necessary step in a nuclear weapon development programme is determining whether a theoretical design of an implosion device, the behaviour of which can be studied through computer simulations, will work in practice. To that end, high explosive tests referred to as “hydrodynamic experiments” are conducted in which fissile and nuclear components may be replaced with surrogate materials.41

48. Information which the Agency has been provided by Member States, some of which the Agency has been able to examine directly, indicates that Iran has manufactured simulated nuclear explosive components using high density materials such as tungsten. These components were said to have incorporated small central cavities suitable for the insertion of capsules such as those described in Section C.9 below. The end use of such components remains unclear, although they can be linked to other information received by the Agency concerning experiments involving the use of high speed diagnostic equipment, including flash X ray, to monitor the symmetry of the compressive shock of the simulated core of a nuclear device.

49. Other information which the Agency has been provided by Member States indicates that Iran constructed a large explosives containment vessel in which to conduct hydrodynamic experiments. The explosives vessel, or chamber, is said to have been put in place at Parchin in 2000. A building was constructed at that time around a large cylindrical object at a location at the Parchin military complex. A large earth berm was subsequently constructed between the building containing the cylinder and a neighbouring building, indicating the probable use of high explosives in the chamber. The Agency has obtained commercial satellite images that are consistent with this information. From independent evidence, including a publication by the foreign expert referred to in paragraph 44 above, the Agency has been able to confirm the date of construction of the cylinder and some of its design features (such as its dimensions), and that it was designed to contain the detonation of up to 70 kilograms of high explosives, which would be suitable for carrying out the type of experiments described in paragraph 43 above.

It appears this is the IAEA’s the final step to officially declare Iran out of compliance with Non Proliferation Treaty they signed.  And that will clear the way for further sanctions or actions by member nations.  This is the end of line for diplomacy other than some “peace missions” by willing fools.  Don’t count Jimmy Carter out.  After all he’s the one who got us into this mess in the first place
