US 'deeply troubled' by Iran nuclear reactor plans

West fears it could yield plutonium for atomic bombs; Iran denies weapons aims, says won't reprocess fuel.

VIENNA - The United States said on Wednesday it was "deeply troubled" by Iran's plans to start a reactor in 2014 that could yield nuclear bomb material while failing to give UN inspectors necessary design information about the plant.
The comments by a US envoy to a board meeting of the UN's International Atomic Energy Agency (IAEA) highlighted deepening Western concern about the heavy water reactor which Iran is building near the town of Arak.
Tension over Iran's nuclear course is rising with talks between Tehran and six powers stalled. Israel, widely assumed to be the Middle East's only nuclear-armed state, sees Iran as the most serious risk to it and has threatened to bomb its nuclear sites if diplomacy and sanctions fail to restrain Tehran.
Iran says the Arak plant will make isotopes for medical and agricultural use. But analysts say this type of facility can also produce plutonium for weapons if the spent fuel is reprocessed - something Iran says it has no intention of doing.
Tasked with ensuring that nuclear material is not diverted for military purposes, the IAEA says Iran must urgently give it design data about Arak, warning that it would otherwise restrict its ability to monitor the site effectively.
"We are deeply troubled that Iran claims that the IR-40 heavy water reactor at Arak could be commissioned as soon as early 2014, but still refuses to provide the requisite design information for the reactor," Joseph Macmanus, the US ambassador to the IAEA, told the 35-nation Board of Governors.
He cited IAEA rules that a member state must inform the Vienna-based UN agency about a nuclear plant, and give design details, as soon as it has decided to build one. Iran says it must only do so before loading nuclear fuel into the reactor.
"Iran's refusal to fulfill this basic obligation must necessarily cause one to ask whether Iran is again pursuing covert nuclear activities," Macmanus said, according to a copy of his speech to the closed-door gathering.
The West suspects Iran is seeking the capability to develop nuclear weapons behind the facade of an atomic energy program.
Western worries about Iran are focused largely on uranium enrichment plants at Natanz and Fordow, as such material refined to a high level can provide the fissile core of an atomic bomb.
But diplomats and experts say Arak could offer Iran a second route to nuclear bombs, if it decided to build them.
