VIENNA — In a significant move, Iran agreed Sunday to provide additional information sought by the UN nuclear agency in its long-stalled investigation of whether Tehran may have worked on nuclear weapons.
Iran insists it never worked on such arms, and the UN’s International Atomic Energy Agency is pushing ahead with its inquiry with expectations that Tehran will continue to assert that all its nuclear activities were meant for peaceful use.
Still, the IAEA’s announcement that Tehran was ready to explain experiments on a type of detonator that the agency says could be used to trigger a nuclear explosion appeared to be another indication that Iran’s new leadership hopes to ease tensions over its nuclear program.
The agency mentioned its concerns about detonator development three years ago as part of a list of activities it said could indicate that Tehran had secretly worked on nuclear weapons. The technology had limited civilian applications, it said, noting its possible application in a nuclear weapon.
Washington and five other world powers will meet Feb. 18 with Iran in Vienna as they work to turn a first step agreement into a pact that permanently curbs Iran’s uranium enrichment in exchange for a full lifting of sanctions on the Islamic republic.
