WASHINGTON — Six months after the revelation of a secret nuclear enrichment site in Iran, international inspectors and Western intelligence agencies say they suspect that Tehran is preparing to build more sites in defiance of United Nations demands.
The United Nations inspectors assigned to monitor Iran’s nuclear program are now searching for evidence of two such sites, prompted by recent comments by a top Iranian official that drew little attention in the West, and are looking into a mystery about the whereabouts of recently manufactured uranium enrichment equipment.
In an interview with the Iranian Student News Agency, the official, Ali Akbar Salehi, head of Iran’s Atomic Energy Organization, said President Mahmoud Ahmadinejad had ordered work to begin soon on two new plants. The plants, he said, “will be built inside mountains,” presumably to protect them from attacks.
“God willing,” Mr. Salehi was quoted as saying, “we may start the construction of two new enrichment sites” in the Iranian new year, which began March 21.
The revelation that inspectors from the International Atomic Energy Agency, the United Nations’ nuclear watchdog, now believe that there may be two new sites comes at a crucial moment in the White House’s attempts to impose tough new sanctions against Iran.
When President Obama publicly revealed the evidence of the hidden site at Qum last September, his aides had hoped the announcement would make it easier to win international support for a fourth round of economic sanctions, particularly from a reluctant China and Russia. Since then, however, the White House has been struggling to convince those countries to go along with the toughest sanctions and the administration is now being forced to scale back its proposed list of sanctions.
The United Nations inspectors operate separately from the diplomats who are developing sanctions. Still, the disclosures may be intended, at least in part, to underscore the belief of Western officials that the Iranian efforts are speeding ahead, and the assertions could aid in efforts to press Iran to open up locations long closed to inspectors.
This article was based on interviews with officials of several governments and international agencies deeply involved in the hunt for additional nuclear sites in Iran, and familiar with the work of the I.A.E.A., the only organization with regular access to Iran’s known nuclear facilities. All the officials insisted on anonymity because the search involves not only satellite surveillance, but also intelligence gleaned from highly classified operations.
American officials say they share the I.A.E.A.’s suspicions and are examining satellite evidence about a number of suspected sites. But they have found no solid clues yet that Iran intends to use them to produce nuclear fuel, and they are less certain about the number of sites Iran may be planning.
In any case, no new processing site would pose an immediate threat or change the American estimates that it will still take Iran one to four years to obtain the capability to build a nuclear weapon. Given the complexity of building and opening new plants, it would probably take several years for the country to enrich uranium at any of the new sites.
One European official noted that “while we have some evidence,” Iran’s heavy restrictions on where inspectors can travel and the existence of numerous tunneling projects were making the detection of any new enrichment plants especially difficult.
Iran boasted several months ago, after the disclosure of the Qum site, that it would build 10 more enrichment plants in coming years. That number was dismissed by American officials and others as a fantasy, far beyond Iran’s abilities, or its budget.
But I.A.E.A. inspectors in Vienna now believe that Mr. Salehi was probably accurate when he referred to two sites.
According to American officials, in recent weeks Israel — which uncovered some of the evidence about Qum — has pressed the case with their American counterparts that evidence points to what one senior administration official called “Qum look-alikes.”
The most compelling circumstantial evidence, people familiar with the inspectors’ view say, is that while Iran appears to be making new equipment to enrich uranium, that equipment is not showing up in the main plant that inspectors visit regularly. Nor is it at the Natanz site in the desert, or the new facility at Qum, which inspectors now visit periodically.
That has heightened suspicions that the equipment, produced in small factories around Iran, is being held in a clandestine storage area for later shipment or installed elsewhere.
The small manufacturing factories, spread around Iran to avoid detection and sabotage, are a particular target of American, Israeli and European intelligence agencies. Several of the plants appear to have been penetrated by intelligence agencies, which are receiving sporadic reports about what Iran is producing and troubles it has encountered in manufacturing centrifuges, the machines that spin at very high speeds to enrich uranium.
Assessments of the potential for hidden enrichment sites beyond Qum, and the continued production of centrifuges, is one of the main subjects of an update to the 2007 National Intelligence Estimate on Iran. That update is being prepared for distribution to President Obama, his top national security team, and selected members of Congress.
Drafts of the highly classified document are now being circulated inside the intelligence community, officials say, but its broader publication has been delayed, in part because of concerns that the early drafts failed to deal with key decisions that Mr. Obama must soon address, especially if long-delayed sanctions fail to change Iran’s current course.
When the last intelligence estimate was published, in November 2007, officials did not know about the Qum plant. Evidence of the plant was discovered later, and contributed to criticism of the report, which also concluded that Iran had halted work on designing nuclear weapons in 2003.
That conclusion, officials say, is also being rewritten, with the Untied States now joining European and Israeli assessments that research and development work, if halted seven years ago, has probably resumed. “The new report walks away, carefully, from many of the key conclusions of the previous version,” said one person familiar with its contents.
Besides Qum, it is unclear whether the new conclusion is based on new intelligence breakthroughs, or a revised interpretation of the existing evidence.
Iran revealed the existence of the Qum plant to the I.A.E.A. last September, apparently after learning that its existence was now known to the West. Iran subsequently told inspectors that it began work on the plant in 2007 and planned to complete it by 2011, and that it would be filled with 3,000 centrifuges.
Though Tehran’s leaders insist the plant, like their entire program, is for peaceful purposes, that is considered too few centrifuges for a commercial site but ideal for a clandestine military plant meant to make bomb fuel.
But little progress has been made. In their most recent report, the inspectors said that some construction at the Qum site was continuing, adding, however, that “no centrifuges had been introduced” as of Feb. 16.
But officials note that for all the digging, nuclear fuel production in Iran is behind schedule. While the Qum plant is only partly built, its main enrichment plant, at Natanz, operates at a tiny fraction of its intended capacity.
If Iran is indeed making plans to build new facilities, it would be in violation of its agreement with the I.A.E.A. In reports and interviews, inspectors have said they received no notice of new Iranian preparatory activity.
In 2003, Iran signed an agreement with the agency to turn over design information on new facilities. Iran repudiated the agreement in March 2007.
