Iran Agrees to Provide Data on Its Detonators

TEHRAN — Iran’s government committed to providing information on detonators for the first time on Sunday as part of a new series of confidence-building measures it agreed to with the United Nations’ nuclear watchdog.

The measures include additional inspections of known nuclear sites and clarifications on questions the watchdog organization, the International Atomic Energy Agency, has asked Iran for years, the semiofficial Iranian Students’ News Agency reported.

Under the agreement, Iran will provide more access to and information about uranium mines near the city of Yazd, a facility near the city of Ardakan, laser production, and its heavy-water reactor near Arak.

The promise of information on detonator research is part of a dossier that has been heavily influencing Western views on Iran’s nuclear program, which Iran says is for energy purposes only, but the United States and other world powers suspect is a cover for producing a nuclear weapons program.

The agreements, made between Iran and the agency over the weekend, need to be completed by May 15.

However, the agency failed to negotiate access to the Parchin military facility, south of Tehran, where the United States suspects explosives have been tested. In 2006, Iran twice allowed inspectors access to the site, but refused entry after that.

At a hearing of the Senate Foreign Relations Committee in Washington on Tuesday, Wendy R. Sherman, under secretary of state for political affairs, said she hoped that Iran would address the issue before July 20, the deadline set by Iran and world powers for a comprehensive agreement on Iran’s nuclear program.

“So we expect, indeed, Parchin to be resolved,” Ms. Sherman said.

Iranian officials confirmed that at least for now, a visit to Parchin was not part of the agreement made over the weekend, the Iranian Students’ News Agency reported.

Data on Iran’s development of a trigger using a technology called “exploding bridge wire” will be provided, the news agency reported. The agency quoted an official as saying that the reasons for developing the detonator technology would be explained.

Also on Sunday, the Islamic Revolutionary Guards Corps expressed its support for Iran’s negotiating team, a further sign that the country’s most influential hard-liners are not opposed to a nuclear deal with the West, despite criticizing the talks conducted by Iran’s foreign ministry in recent months.

“The diplomatic apparatus has met the aspirations of every single Iranian by responding explicitly, firmly and transparently to the nonsense of the front of the enemies,” the Revolutionary Guards said in a statement. “Especially the silly, threatening and impolite remarks of the American officials.”

On Tuesday, Iran will celebrate the 35th anniversary of the 1979 Islamic Revolution, with state-sponsored rallies scheduled across the country.

In an interview with state television, one of Iran’s top negotiators, Deputy Foreign Minister Abbas Araghchi, emphasized that a nuclear deal would in no way mean a normalization of ties with the United States.

“We have problems with the U.S.A. over dozens of issues, such as the Palestinian issue, issues related to the Middle East, the Syrian issue, human rights, seeking hegemony, global hegemony, and issues related to excessive demands and bullying,” he said. “All these are still there. Nothing has changed. The U.S.A. is still the Great Satan in our view.”
