Iran agrees to clarify nuclear detonators to IAEA

Iran showing more cooperation

Iran agreed Sunday to clarify to the UN atomic agency its need for detonators used in a nuclear device, as part of a probe into allegations of its past weapons work.
The move is part of seven new steps agreed between Iran and the International Atomic Energy Agency to increase transparency over Tehran's controversial nuclear drive.
And it appears to be the first time in years Iran has agreed to tackle IAEA suspicions that its nuclear work prior to 2003 had "possible military dimensions".
The development comes as Iran is set to resume nuclear talks with world powers later this month, after clinching an initial accord in November to curb uranium enrichment and open up nuclear facilities to allay concerns Tehran is seeking to acquire atomic weapons
Capping two-days of talks in Tehran with Iranian officials, the IAEA said Iran agreed to provide "information and explanations for the agency to assess Iran's stated need or application for the development of Exploding Bridge Wire (EBW) detonators."
According to the IAEA, Iran told the agency in 2008 that it had developed EBWs for "civilian and conventional military applications" but has yet to explain its "need or application for such detonators."
Such fast, high-precision detonators could be used in some civilian applications but are mostly known for triggering a nuclear chain reaction, which the IAEA believes form "an integral part of a programme to develop an implosion type nuclear device."
There was no immediate reaction from the Iranian side.
But earlier Iran's envoy to the Vienna-based IAEA, Reza Najafi, said that "seven more practical steps" had been agreed between the two sides in a deal that would be implemented by May 15.
Six other steps had been agreed under a framework deal struck on November 11.
In the latest agreement, the IAEA will also have "managed access" to the Saghand uranium extraction mine in and the Ardakan yellowcake facility where an impure state of uranium oxide is prepared to be fed into centrifuges for enrichment.
Officially unveiled in April 2013, the plant in Ardakan receives raw material from Saghand, some 120 kilometres (75 miles) away. It can reportedly produce up to 60 tonnes of yellowcake annually.
Arak reactor remains in spotlight
Iran also agreed to submit updated design information and finalise a safeguards mechanism for the so-called heavy water reactor under construction in Arak,.
The reactor is of international concern because it could theoretically provide Iran with a second route to a nuclear bomb -- an alternative to highly enriched uranium -- through extraction of weapons-grade plutonium from spent fuel if it also builds a reprocessing facility.
IAEA director general Yukiya Amano is reportedly expected to brief the agency's broad of governors on the details of the latest agreement.
Last month he raised expectations that alleged weaponisation studies would be broached in future talks with Iran, saying the time was ripe to ask "more difficult" questions.
Najafi said the weekend talks with IAEA experts were "constructive" and broached "the progress in implementation of practical steps" required of Iran in the November deal.
That framework agreement required Tehran to take six steps that included visits by UN inspectors to the unfinished site in Arak and a uranium mine in the south.
Iran's enrichment activities are in defiance of repeated UN Security Council demands and resolutions, amid suspicions in the West and Israel that Tehran's nuclear drive masks military objectives, a claim it has repeatedly denied.
A sore issue in long-running discussions between Iran and the IAEA has been the Parchin military site near Tehran, where the UN agency suspects research pertaining to weapons development was conducted.
But Iran argues that Parchin is not a nuclear-declared site and therefore not subject to UN inspections.
Iran's Atomic Energy Organisation spokesman, Behrouz Kamalvandi, said a visit to Parchin was not included in the new seven-step deal.
The IAEA says it needs to examine the site, pointing to new information it has uncovered since its last visits in 2005.
Iran and six world powers are due to resume nuclear talks on February 18, on reaching a long-term nuclear deal.
Full cooperation with the IAEA is a key demand of the P5+1 -- Britain, China, France, Russia and the United States plus Germany.
