Gareth Porter reports: The report of the International Atomic Energy Agency (IAEA) published by a Washington think tank Tuesday repeated the sensational claim previously reported by news media all over the world that a former Soviet nuclear weapons scientist had helped Iran construct a detonation system that could be used for a nuclear weapon.

But it turns out that the foreign expert, who is not named in the IAEA report but was identified in news reports as Vyacheslav Danilenko, is not a nuclear weapons scientist but one of the top specialists in the world in the production of nanodiamonds by explosives.

In fact, Danilenko, a Ukrainian, has worked solely on nanodiamonds from the beginning of his research career and is considered one of the pioneers in the development of nanodiamond technology, as published scientific papers confirm.

It now appears that the IAEA and David Albright, the director of the International Institute for Science and Security in Washington, who was the source of the news reports about Danilenko, never bothered to check the accuracy of the original claim by an unnamed “Member State” on which the IAEA based its assertion about his nuclear weapons background.

Albright gave a “private briefing” for “intelligence professionals” last week, in which he named Danilenko as the foreign expert who had been contracted by Iran’s Physics Research Centre in the mid-1990s and identified him as a “former Soviet nuclear scientist”, according to a story by Joby Warrick of the Washington Post on Nov. 5.

The Danilenko story then went worldwide.

The IAEA report says the agency has “strong indications” that Iran’s development of a “high explosions initiation system”, which it has described as an “implosion system” for a nuclear weapon, was “assisted by the work of a foreign expert who was not only knowledgeable on these technologies, but who, a Member State has informed the Agency, worked for much of his career in the nuclear weapon program of the country of his origin.”

The report offers no other evidence of Danilenko’s involvement in the development of an initiation system.

The member state obviously learned that Danilenko had worked during the Soviet period at the All-Russian Scientific Research Institute of Technical Physics in Snezhinsk, Russia, which was well known for its work on development of nuclear warheads and simply assumed that he had been involved in that work.

However, further research would have revealed that Danilenko worked from the beginning of his career in a part of the Institute that specialised in the synthesis of diamonds. Danilenko wrote in an account of the early work in the field published in 2006 that he was among the scientists in the “gas dynamics group” at the Institute who were “the first to start studies on diamond synthesis in 1960”.
